Energy requiring metabolic pathways that yield complex molecules from simpler precursors are: anabolic. The correct option is (B).

Anabolic pathways are those metabolic pathways in which simple molecules are combined to form more complex molecules. These pathways require energy, usually in the form of ATP, to drive the chemical reactions that synthesize complex molecules from simpler precursors.

Anabolic pathways play an important role in building the macromolecules needed for cellular structures and functions, such as proteins, nucleic acids, and complex carbohydrates. These pathways are also involved in the storage of energy in the form of glycogen, lipids, and other complex molecules.

Examples of anabolic pathways include protein synthesis, DNA replication, and glycogen synthesis. These pathways are often linked to catabolic pathways, which break down complex molecules into simpler ones and release energy.

Together, anabolic and catabolic pathways maintain the balance of chemical reactions in the cell, allowing it to grow, divide, and carry out its functions.

The correct statement concerning the alternative complement system is that it is activated by pathogen surfaces and it doesn't require antibodies.

The complement system is a portion of the immune system that aids in the recognition and destruction of pathogens, such as bacteria and viruses. The alternative complement system is one of the three pathways that activate the complement system. The alternative complement system is activated by pathogen surfaces and it doesn't require antibodies. Rather than that, it employs a series of spontaneous reactions to identify and target pathogens.The other two pathways of the complement system are the classical pathway and the lectin pathway. Unlike the alternative complement system, the classical and lectin pathways are activated by antibodies. The alternative complement pathway plays a critical role in the defense of the host against infection and inflammation, as well as in the clearance of apoptotic cells and immune complexes from the bloodstream.

Explanation:

If an organism has more specialized cells, its cells have their own function.

1. Cells in an organism are divided on the basis of their specialization.

2. They are called differentiated cells in scientific terms.

3. Differentiated cells are found in different organs.

4.They perform function for which the organ is specific for.

5. Example, heart has cardiac cells, which functions to pump blood.

6. The characteristics of cardiac cells are that they are strong enough to resist the pressure of blood flow.

7. In the same way, liver has differentiated cells, which are called hepatic cells.

8. These perform function of metabolism and formation of bile.

9. Kidney has nephrons as differentiated cells.

1. Time taken by Gary and Diane to complete the garden if they divide the soil preparation equally and the planting equally is 32 hours.

2. Time taken by the two to complete the garden if they use comparative advantage and specialize in soil preparation or planting is 34 hours.

1. To calculate the time taken by Gary and Diane to complete the garden, let's write the time taken by Gary to prepare the soil to be x hours. So, the time taken by Diane to prepare the soil will also be x hours. As given, Diane can plant 100 flowers in 12 hours. Thus, Diane can plant 25 flowers in 3 hours. Therefore, the time is taken by Diane to plant 100 flowers

= (100/25) × 3 = 12 hours.

Now, the time taken by Gary to plant 100 flowers will also be 12 hours. Therefore,

total time taken by both Gary and Diane to complete the garden = Time taken for soil preparation + Time taken for planting

= 2x + 12 hours = (2 × 10) + 12

= 32 hours

2.  To calculate the time taken by the two to complete the garden if they use comparative advantage and specialize in soil preparation or planting, we know that Diane can prepare the soil in 10 hours while Gary can prepare the soil in 20 hours. Therefore, Diane should prepare the soil. Now, the time is taken by Diane to prepare the soil = 10 hours. Diane can plant 100 flowers in 12 hours while Gary can plant 100 flowers in 24 hours. Therefore, Gary should plant the flowers.

Now, the time is taken Gary to plant the flowers = 24 hours. Therefore,

total time taken by both Gary and Diane to complete the garden = Time taken for soil preparation + Time taken for planting

= 10 + 24

= 34 hours

Geneticists believed that the genetic code would be composed of triplet sequences and be nonoverlapping for several reasons such as combination of amino acids in protein synthesis, indirect evidence from frame-shift mutations and experimental evidence by using synthetic RNA molecules.

Firstly, they knew that the genetic code needed to contain enough information to specify all 20 amino acids used in protein synthesis. With a triplet code, there are 64 possible combinations (4 nucleotide bases raised to the power of 3), which is more than enough to account for the 20 amino acids.

Secondly, Crick, Brenner, and colleagues' work on frame-shift mutations provided indirect evidence for a triplet code. They observed that when one or two nucleotide bases were added or removed from a DNA sequence, the protein produced was often nonfunctional. However, when three bases were added or removed, the protein function could be restored. This indicated that the genetic code was read in groups of three bases, and that adding or removing one or two bases shifted the reading frame, disrupting the protein sequence.

Experimental evidence for the triplet nature and nonoverlapping nature of the genetic code was obtained through the work of Nirenberg and Khorana in the 1960s. They used synthetic RNA molecules with known sequences and observed the resulting amino acids produced during in vitro translation. By testing different RNA sequences, they were able to deduce which triplet codons coded for each amino acid.

Thus, a combination of theoretical considerations, indirect experimental evidence from frame-shift mutations, and direct experimental evidence from in vitro translation experiments led geneticists to conclude that the genetic code was composed of triplet sequences and was nonoverlapping.

Explanation:

The pH of blood is a measure of its acidity or basicity. The normal pH range for blood is between 7.35 and 7.45, which is slightly basic. This pH range is crucial for the proper functioning of the body's enzymes and organs.

Blood pH is regulated by the respiratory and renal systems. The respiratory system, through the process of breathing, controls the level of carbon dioxide in the blood.

Carbon dioxide can combine with water to form carbonic acid, which can lower the pH of the blood. When the blood pH drops below 7.35, the body increases breathing rate to exhale more carbon dioxide, which raises the pH back to normal.

The renal system, through the process of urine production, also plays a role in regulating blood pH.

The kidneys can excrete or retain acids or bases, depending on the pH of the blood. If the blood pH rises above 7.45, the kidneys excrete more bases to bring the pH back to normal. If the blood pH drops below 7.35, the kidneys retain more acids to raise the pH back to normal.

Answer:

The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place). A substrate enters the enzyme's active site. This results in the formation of the enzyme-substrate complex.

Explanation:

In certain reactions, a single substrate is degraded into several products. In others, two substrates combine to form a bigger molecule or to swap components. In fact, each form of biological reaction you can think of has an enzyme to accelerate it up!

The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place).

Proteins are made up of amino acid units, and the active site in protein enzymes receives its features from the amino acids it's made up of. These amino acids can have big or small side chains, acidic or basic side chains, hydrophilic or hydrophobic side chains.

The amino acid sequence present at the active site, as well as their placements in 3D space, give the active site its distinct size, shape, and chemical activity. Because of these amino acids, the active region of an enzyme is specially designed to attach to a specific target—the enzyme's substrate or substrates—and assist them in undergoing a chemical process.

Only in the citric acid cycle does each glucose molecule yield 2 ATP and 6 NADH molecules.

Two pyruvate molecules are produced from one glucose molecule. The pyruvate dehydrogenase complex enzyme then transforms these pyruvate molecules into Acetyl-CoA. One acetyl-CoA generates one GTP (the ATP equivalent), one FADH2, and three NADH. Two acetyl CoA (or one glucose molecule) will result in the synthesis of two ATP, two FADH2, and six NADH.

The citric acid cycle is a chain of redox and decarboxylation events that eliminate carbon dioxide and high-energy electrons. In the following route, the electrons momentarily trapped in NADH and FADH2 molecules are used to produce ATP. At each cycle turn, substrate-level phosphorylation yields one molecule of either GTP or ATP. The cyclic pathway is not compared to a linear one.

Thus, we can conclude that each glucose molecule only produces 2 ATP and 6 NADH molecules during the citric acid cycle.

The relative concentrations of ATP and ADP control the cellular rates of metabolic processes.

Cellular respiration is the process that produces ATP in living organisms. It is the biochemical pathway that releases energy stored in food molecules and uses it to produce ATP from ADP and inorganic phosphate. The energy released in cellular respiration is used to power the activities of the cell.

The relative concentrations of ATP and ADP control the cellular rates of metabolic processes. ATP inhibits the rate of ATP-forming processes while it stimulates the rate of ATP-consuming processes. ADP, on the other hand, stimulates the rate of ATP-forming processes while it inhibits the rate of ATP-consuming processes. Therefore, a cell with higher ATP concentration will tend to consume ATP and produce ADP while a cell with higher ADP concentration will produce ATP.
