Question

Quizplus · Accepted Answer

Lactic acid is produced when no oxygen is present and pyruvic acid is converted.

Answer: I
 Anaerobic means without oxygen. Lactic acid fermentation is an example of anaerobic respiration.

Answer: C
 Pyruvic acid is the product of glycolysis, which occurs in the cytosol of the cell.

Answer: D
 Acetyl coenzyme A is the molecule that is produced when pyruvic acid enters the mitochondria to begin the citric acid cycle.

Answer: E
 NAD is an electron carrier molecule that plays a crucial role in both glycolysis and the electron transport chain.

Answer: F
 The mitochondria is the organelle responsible for aerobic respiration, including the citric acid cycle and electron transport chain.

Answer: A
 The cytosol is the location where glycolysis occurs, which is the first step of cellular respiration.

Answer: B
 The citric acid cycle is the second step of cellular respiration that occurs in the mitochondria to produce ATP.

Answer: H
 The electron transport chain is the final step of cellular respiration that occurs in the inner membrane of the mitochondria and requires oxygen as the final electron acceptor.
