Question

The functions of ATP are ___________

(a) ATP acts as the main source of energy in cells

(b) Plays a role in transporting solutes and proteins across cell membranes

(c) Contribute to the building blocks of DNA

(d) All of the mentioned

This question was addressed to me during an interview.

Origin of the question is Enzymes as Biological Catalysts topic in section Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer 1

Correct answer is (d) All of the mentioned

The explanation is: Adenosine triphosphate or ATP is the main source of energy in cells. It releases energy by breaking into Adenosine diphosphate (ADP) and inorganic phosphate. It plays a role in solute transport across cell membranes through ATPase channels. It is the precursor of Adenine, which helps in the formation of DNA.
