A single "turn" of the citric acid cycle will yield:

1 ATP, 3 NADH, and 1 FADH2.

The NET result of a single glycolysis run is the formation of:

2 NADH and 2 ATP.

The initial reaction of the Krebs cycle involves the addition of a:

2-carbon molecule to a 4-carbon molecule.

Arrange the following electron acceptors in the proper order in which they participate in electron transport. • Cytochrome c • Oxygen • Cytochrome c oxidase

Cytochrome c, Cytochrome c oxidase, and Oxygen.

A single "turn" of the Krebs cycle involves three different decarboxylation reactions. True or False?

False

Under aerobic conditions, the end-product of glycolysis is further reduced to yield more ATP. True or False?

False

The production of ATP as a result of the activity of the electron transport system is termed substrate-level phosphorylation. True or False?

False. It is called oxidative phosphorylation.

The electrons that are transferred through the electron transport system initially belonged to:

NADH and FADH2.

During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. True or False?

True

The Krebs cycle occurs in the mitochondria. True or False?

True

When oxygen accepts electrons, water is produced as a byproduct. True or False?

True

Before entering the citric acid cycle, pyruvate is converted to:

acetyl-CoA

intermembrane space to the matrix.

Under anaerobic conditions, the end-product of glycolysis is converted to:

lactic acid

In glycolysis, glucose is converted to:
