Biology Cellular Respiration Review

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.

Front

What is produced during glycolysis?

Back

During glycolysis, 2 NADH molecules and 4 ATP (net gain of 2 ATP) are produced.

Front

What happens to glucose in glycolysis?

Back

Glucose is phosphorylated and split into two 3-carbon compounds.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain, where it contributes to ATP production.

Front

What is the electron transport system (ETS)?

Back

The ETS is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP.

Front

How many ATP are generated in the ETS?

Back

32 ATP are generated in the electron transport system.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What are the main products of the Krebs cycle?

Back

The main products of the Krebs cycle are NADH, FADH2, ATP, and carbon dioxide.

Front

What is the relationship between lactic acid and pyruvic acid?

Back

Lactic acid is formed from pyruvic acid during anaerobic respiration.

Front

What is the function of coenzyme A in cellular respiration?

Back

Coenzyme A is essential for the transport of acetyl groups into the Krebs cycle.
