THE KREBS CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
NADH from the Krebs Cycle moves on to the
A
Calvin Cycle
B
Citric Acid Cycle
C
Electron Transport Chain
D
Glycolysis
Explanation: 

Detailed explanation-1: -Although some ATP is generated via the GTP derived from the Krebs cycle, most of the ATP generated during aerobic respiration comes from oxidative phosphorylation . The NADH and FADH generated during the Krebs cycle fuels the electron transport chain which drives this process, ultimately producing 38 molecules of ATP.

Detailed explanation-2: -Electrons from NADH enter the electron transport chain in complex I, which consists of nearly 40 polypeptide chains (Figure 10.8). These electrons are initially transferred from NADH to flavin mononucleotide and then, through an iron-sulfur carrier, to coenzyme Q-an energy-yielding process with
