THE KREBS CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is used to make carbon dioxide, NADH, ATP, and FADH2?
A
Acetyl-CoA
B
Citric acid
C
Glycolysis acid
D
Acetic acid
Explanation: 

Detailed explanation-1: -The pathway uses acetyl CoA and oxaloacetate to produce carbon dioxide, ATP, NADH, and FADH2.

Detailed explanation-2: -Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.

Detailed explanation-3: -Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made.

Detailed explanation-4: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.

Detailed explanation-5: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
