Question 0

Fermentation

Answer 0

Metabolic pathway that breaks down carbohydrates to produce ATP; does not require oxygen.

Question 1

Aerobic Respiration

Answer 1

Oxygen-requiring metabolic pathway that breaks down carbohydrates to produce ATP.

Question 2

Glycolysis

Answer 2

Set of reactions in which glucose or another sugar is broken down to two pyruvate for a net yield of two ATP.

Question 3

Pyruvate

Answer 3

Three-carbon end product of glycolysis.

Question 4

Substrate-Level Phosphorylation

Answer 4

A reaction that transfers a phosphate group from a substrate directly to ADP, thus forming ATP.

Question 5

Krebs Cycle

Answer 5

Cyclic pathway that, along with acetyl-CoA formation, breaks down pyruvate to carbon dioxide during aerobic respiration.

Question 6

Alcoholic Fermentation

Answer 6

Anaerobic carbohydrate breakdown pathway that produces ATP and ethanol. Begins with glycolysis; end reactions regenerate NAD+ so glycolysis can continue.

Question 7

Lactate Fermentation

Answer 7

Anaerobic carbohydrate breakdown pathway that produces ATP and lactate.
