Answer #1

The most important contribution of the citric acid cycle to cellular respiration is (D) transformation of acetyl-CoA and corresponding generation of high - energy electron carriers.

Citric acid cycle doesn't produce large quantities of ATP. Even if it releases CO2, it is not it's main purpose. Citric acid cycle doesn't involve glucose. Hence the best option is D.

These high energy electron carriers transfer their electrons in oxidative phosphorylation to produce large quantity of ATPs.

One molecule of acetyl CoA generates the following in the citric acid cycle: 3 NADH, 1 FADH2 and 1 GTP. A single round of b-oxidation generates: 1 NADH and 1 FADH2. How much ATP is generated from a C-10 fatty acid after it has been completely metabolized to CO2 and H2O? FADH2=2ATP and NADH=3ATP in electron transport.

1.in this phase of cellular respiration, glucose is completely broken down into carbon dioxide gas, some ATP is produced, and many molecules of NADH and some FADH2 are produced. glucose breakdown oxidative phosphorylation 2. In this phase of cellular respiration, NADH and FADH2 are used to power the electron transport chain, which in turn creates the conditions needed for the ATP synthase enzyme to make ATP. glucose breakdown oxidative phosphorylation
