What do aerobic respiration and anaerobic respiration have in common?

Both begin with glycolysis.

Both occur in mitochondria.

Both require oxygen to proceed.

Both end with the electron transport chain.

During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during glycolysis?

Glycolysis produces ATP and pyruvate by oxidizing water.

Glycolysis produces ATP and pyruvate by oxidizing glucose and NAD+.

Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.

Glycolysis produces CO2, ATP, and pyruvate by reducing glucose.

During which process is water produced?

alcohol fermentation

acetyl CoA formation

electron transport chain

citric acid cycle

What is the main difference between aerobic respiration and anaerobic respiration?

Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not.

Aerobic respiration occurs during photosynthesis, but anaerobic respiration occurs during cellular respiration.

Aerobic respiration produces ATP, but anaerobic respiration does not.

Aerobic respiration involves glycolysis, but anaerobic respiration does not.

The graphic shows the citric acid cycle. During the citric acid cycle, what happens to acetyl-CoA?

It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule.

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule.

It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.
