Question

During a long bout of sustained exercise, in which order will your body's energy stores/sources be used?
		fatty acids, glycogen stored in the liver, glycogen stored in the muscle, ATP stored in the muscle ATP stored in muscle, glycogen stored in muscle, glycogen stored in the liver, fatty acids ATP stored in muscle, glycogen stored in the liver, glycogen stored in the muscle, fatty acids ATP stored in muscle, fatty acids, glycogen stored in the muscle, glycogen stored in the liver glycogen stored in muscle, ATP stored in the muscle, glycogen stored in the liver, fatty acids

In the absence of oxygen, fermentation:
		regenerates NADH from the reduction of pyruvate. generates ATP from the oxidation of pyruvate. regenerates NAD+ from the oxidation of pyruvate. regenerates NAD+ from the reduction of pyruvate. generates ATP from the reduction of pyruvate.

During lactic acid fermentation, pyruvate is:
		carboxylated. reduced. phosphorylated. oxidized. hydrogenated.

Which of the following processes produces the highest number of reduced electron carriers and thus the greatest potential for generating ATP?
		the citric acid cycle glycolysis Each stage contributes equally. pyruvate oxidation

Answer 1

1) Question No 1:ATP stored in muscle, glycogen stored in muscle, glycogen stored in the liver, fatty acids.

2) Question No 2 : regenerates NAD⁺ from the oxidation of pyruvate.

3) Question No 3: hydrogenated.

4) Question No 4 : glycolysis (3),in cytric acid cycle and pyruvate oxidation ,number of reduced electron career is 2.
