Question

Quizplus · Accepted Answer

NAD (nicotinamide adenine dinucleotide) carries high-energy electrons from the breakdown of glucose to the electron transport system in the mitochondria.

Answer: F
 The electron transport system is located in the mitochondria and is responsible for producing the majority of ATP in aerobic respiration.

Answer: D
 Acetyl coenzyme A is produced during the breakdown of pyruvic acid and enters the citric acid cycle, carrying high-energy electrons to the electron transport system.

Answer: J
 Glycolysis is the process by which glucose is broken down into pyruvic acid, producing a small amount of ATP and high-energy electrons that are carried by NAD to the electron transport system.

Answer: G
 Lactic acid fermentation is an anaerobic process in which pyruvic acid is converted into lactic acid, producing a small amount of ATP but no high-energy electrons for the electron transport system.

Answer: I
 Anaerobic respiration refers to processes that do not require oxygen, such as lactic acid fermentation or alcohol fermentation. Aerobic respiration, which does require oxygen, includes the citric acid cycle and electron transport system.

The remaining choices, A, B, and C are not directly related to high-energy electron transport and therefore do not match the given description.
