Question

During which stage in the complete oxidation of glucose is the greatest number of ATP molecules formed from ADP –?
(a)Glycolysis
(b)Krebs cycle
(c)Electron transport chain
(d)Conversion of pyruvate acid to acetyl CoA

Answer 1

Hint: They are a series of compounds where it makes use of electrons from an electron carrier to develop a chemical gradient. It might be wont to power oxidative phosphorylation. The molecules present within the chain comprise enzymes that are protein complex or proteins, peptides, and far more.

Complete answer:
The complete oxidation of glucose is the greatest number of ATP molecules produced from ADP throughout the step of the electron transport chain. In glycolysis 4 ATP and ${2NADH}_2$ molecules are produced. These $2NADH_2$ molecules visit the electron transport chain. In oxidative decarboxylation, no ATP molecule is produced but two molecules of $2NADH_2$ are made up of two molecules of pyruvate. These two $NADH_2$ attend the electron transport chain. In Kreb's cycle 2 ATP, $6NADH_2$ and $2FADH_2$ molecules are produced from two molecules of acetyl Co-A. These $NADH_2$ and $2FADH_2$ attend the electron transport chain. In the electron transport chain all $2NADH_2$ and $2FADH_2$ pass to electron carriers and yield 3 ATP and a couple of ATP molecules per $2NADH_2$ and $2FADH_2$ respectively. Thus, 4 ATP are made in glycolysis, 2 ATP within the Krebs cycle, and 34 ATP from the electron transport chain. 40 ATP and a couple of ATP molecules are utilized throughout glycolysis. So, the entire gain of ATP molecules throughout one full oxidation of a glucose molecule is 38 ATP.

Additional information:
Electron transport is defined as a series of redox reactions that's almost like the relays. It's a part of aerobic respiration. It’s the sole introduction of glucose metabolism that creates the use of atmospheric oxygen. When electrons are passed from one component to a different one until the top of the chain the electrons reduce molecular oxygen thus producing water. The need for oxygen within the final phase might be witnessed within the reaction that involves the need for both oxygen and glucose.

So, the correct answer is 'Electron transport chain'.

Note: Large amounts of ATP might be produced through a highly efficient method termed oxidative phosphorylation. ATP may be a fundamental unit of metabolism. The electrons are transferred from the electron donor to the electron acceptor resulting in the assembly of ATP. It’s one of the vital phases within the electron transport chain. Compared to the other part of respiration an outsized amount of ATP is produced during this phase.
