Question

A) The formation of DNA from individual nucleotides is best described as:

1. a process that will have a net yield of energy.

2. a process that will have no effect on disorder in the universe.

3. an anabolic reaction.

4. a catabolic reaction.

5. a spontaneous reaction

B)In a C4 plant where does the Calvin cycle predominantly take place?

1. in the vascular tissue.

2. in every cell in the plant.

3. in the bundle sheath cells of leaves.

4. in the mesophyll cells or leaves.

5 in the roots.

C)The formation of a polysaccharide from monosaccharides is best described as:

1. a process that will have a net yield of energy.

2. a process that will not increase disorder in the universe.

D) Chloroplast ATP synthase is present in which membrane?

1. the thylakoid membrane.

2. the mitochondrial inner membrane.

3. the chloroplast outer membrane.

4. the mitochondrial outer membrane.

5. the cristae

3. an anabolic reaction.

4. a catabolic reaction.

5. a spontaneous reaction.

Answer 1

A. Third option is the right answer. Building up complex molecule from a simple molecule is known as anabolic process. Anabolic process take up energy to form the complex molecule, the nucleotides forming the DNA is an anabolic process.

B. Third option is the right answer. The Calvin cycle takes place in the bundle sheath of the leaves in the C4 plants. Bundle sheath is layer of cells which surrounds the vascular bundle in the leaves. The vascular bundle consists of xylem and phloem.

C. Third option is the right answer. The formation of polysaccharides from the monosaccharides or monomer unit of sugar is an anabolic reaction. In anabolic reaction there is an utilization of energy to form the polymer of sugar or the polysaccharide and it leads to complex molecules.

D. First option is the right answer. The chloroplast ATP synthase is present in the thylakoid membrane of the chloroplast. Chloroplasts is the location where the photosynthesis takes place. The function of ATP synthase is to produce the ATP.

Please give a thumbs up if the answer helped you. Thank you! :)
