Question

NADH --> NAD⁺ + 2e^- + H⁺

Question options:

	demonstrates that NADH can reduce to other molecules
	is the equation for the reduction of NADH
	is the equation for the oxidation of NADH
	demonstrates that NADH can donate e- to other molecules

Glycolysis results in

Question options:

	the synthesis of ATP via substrate-level phosphorylation
	the complete oxidation of glucose
	the reduction of electron carriers
	the sythesis of ATP via oxidative phosphorylation

Pyruvate oxidation (which happens twice for every molecule of glucose)

Question options:

	means that pyruvate passes electrons to NAD+
	means that pyruvate reduces NAD+
	results in two of the carbons that started out in glucose being released as CO2
	occurs in the mitochondria of both prokaryotes and eukaryotes.

Answer 1

Ans.1. Option first  is the correct option.

Explanation:- It is a biochemical reaction in which NADH loses electrons and the lost elctrons are captured by other molecules. As the other molecule accepts the electrons , it get reduced. So NADH reduces other molecules . So this reaction demonstrate that NADH can reduce other molecules.

Ans.2. Option fourth is the correct option.

Explanation:- Glycolysis results in the synthesis of ATP via oxidative phosphorylation. It does not involve the substrate level phosphorylation. It is because it does not take oxygen. But it release ATP by oxidative phosphorylation from the reduced power NADH. It occurs in mitochondria.

Ans.3. Option third is the correct answer.

Explanation:- pyruvate oxidation result in two of the ca4bons that started out in the glucose being released as CO2. So pyruvate oxidation results in the production of the carbon dioxide . It occurs in the mitochondrial matrix.
