Respiration & Gaseous Exchange
Solution
The role of ATP include all the following activities except
A
provision of energy to do work in living organisms
B
transmission of nerve impulse
C
keeping the body warm in homoithermic animals
D
producing water during aerobic respiration
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
The correct answer is D
Although, ATP (Adenosine Triphosphate) is not directly involved in the transmission of nerve impulses. Nerve impulses are transmitted through electrical and chemical signals, such as action potentials and neurotransmitters. However, producing water during aerobic respiration isn't the primary role of ATP; rather, ATP is the energy currency of the cell, while water is a byproduct of the electron transport chain, a key step in aerobic respiration.
