What is a metabolic process that requires oxygen?

Back

Aerobic processes.

Front

What is the series of reactions in which pyruvate is broken down into carbon dioxide inside the mitochondria of cells?

Back

Krebs cycle (also called the tricarboxylic acid cycle and the citric acid cycle).

Front

What is the anaerobic process that is the first stage of cellular respiration in which glucose is broken down into two molecules of pyruvate?

Back

Glycolysis.

Front

What is the metabolic process in which pyruvate is broken down and electron-carrier molecules are used to produce ATP through electron transport?

Back

Aerobic respiration.

Front

What is a metabolic process that does not require oxygen?

Back

Anaerobic processes.

Front

What is the primary function of glycolysis in cellular respiration?

Back

To break down glucose into two molecules of pyruvate.

Front

What are the end products of the Krebs cycle?

Back

Carbon dioxide, ATP, and electron carriers (NADH and FADH2).

Front

What role do electron carriers play in aerobic respiration?

Back

They transport electrons to the electron transport chain to produce ATP.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration does not.

Front

What is produced during anaerobic respiration?

Back

Lactic acid or ethanol, depending on the organism.
