Lactic acid is the result of LDH (lactic acid dehydrogenase)mediated __________ of pyruvic acid with electrons taken from NADH + H⁺.

The transport of protons from the intermembrane space to the mitochondrial matrix occurs via

Accumulation of lactic acid contributes to

The electron transport system is a series of _________ reactions.

Catabolic reactions use energy to synthesize large molecules.

Prior to entering the citric acid cycle,amino acids must be reductively deaminated.

______________ is the opposite of glycogenesis.

Which of the following is NOT a molecule of the electron transport system?

To go through glycolysis,_________ ATP per glucose molecule must be "invested" in order to activate the glucose molecule.

Fatty acid metabolism

Fatty acids are NOT an energy source for

The importance of the citric acid cycle in energy production is the formation of significant amounts of

Most of the glucose secreted by the liver during fasting is due to

Acetyl CoA and NAD are the end-products of the citric acid cycle.

Proline is an essential amino acid only in children.
