Question

What do you call that high energy molecule that was formed at the end of cellular respiration? A. ADP B. ATP C. NAD

Answer 1

The high energy molecule formed at the end of cellular respiration is B. ATP.

Answer 2

Answer:

Option B, ATP

Explanation:

In the process of respiration, there are four major stages –

A) Glycolysis – In glycolysis, 6 carbon glucose is transformed into pyruvate along with release of ATP and conversion of NAD+ to NADH.

B) Pyruvate oxidation – Pyruvate is converted to Acetyl CoA along with release of CO2 and generation of NADH.

C) Citric acid cycle – Acetyl CoA combines with four carbon molecule to produce NADH, ATP, FADH2 and carbon dioxide is released.

D) Oxidative phosphorylation – In this last stage, NADH and FADH2 are converted back into NAD+ and FAD. Electrons flow back into the matrix thereby producing ATP.

Thus, it it clear that in the last stage of cellular respiration ATP molecule is produced.
