Question

use the diagram above to answer the next question. the radioisotope phosphorus - 32 was available during dehydration synthesis. which of the following cell structures would produce molecules that has phosphorus - 32? select one: a. structure f b. structure b c. structure e d. structure k

Explanation:

Phosphorus - 32 would be incorporated into molecules synthesized during dehydration synthesis. Ribosomes (Structure E) are involved in protein synthesis (a type of dehydration - synthesis reaction where amino acids are joined together). Proteins can contain phosphorus in certain cases, such as in phosphorylated proteins. Structure F is a mitochondrion which is mainly involved in cellular respiration, Structure B is the nucleus which is mainly for storing genetic information, and Structure K is the cell wall which is mainly structural and not directly involved in synthesizing molecules with phosphorus - containing components during dehydration synthesis.

Answer:

c. Structure E
