Summary Introduction
Introduction:
The ATP (adenosine triphosphate) production is vital for the functioning of the various systems and biochemical processes in the cell. The ATP can be generated through aerobic and anaerobic respiration. Several

The maximal recovery of energy from oxidation of glucose to CO2 and H2O requires
the coordination of the glycolysis, tricarboxylic acid cycle, the electron transport
chain and the ATP synthase. During these processes each molecule of glucose
generates:
6 molecules of NADH and 1 molecules of FADH2.
10 molecules of NAD* and2 molecules of FADH2.
10 molecules of NADH and 2 molecules of FAD.
10 molecules of NADH and 2 molecules of FADH2.
10 molecules of NAD* and 1 molecules of FADH2.
The redox-active moiety of NAD+ is derived from the vitamin—
riboflavin.
niacin.
cobalamin.
biotin.
pantothenic acid.
Lactate dehydrogenase (LDH) plays an essential role in an exercising muscle, especially when the level of excursion surpasses the ability of circulatory systems ability
to supply adequate oxygen. What is the main reason LDH is so important to the muscle under these conditions?
It produces one mole of ATP via substrate level phosphorylation.
It resupplies NAD+ to glyceraldehyde 3-phosphate dehydrogenase.
It decreases pH thus decreasing the dissociation rate of oxygen from hemoglobin
It produces NADH for energy while converting pyruvate into lactate.
It removes excess lactic acid from the muscle to create pyruvate.
