What is glycolysis?

Back

Glycolysis is the metabolic process that converts glucose into pyruvate, producing a small amount of ATP and NADH. It occurs in the cytoplasm and does not require oxygen.

Front

Does glycolysis require oxygen?

Back

No, glycolysis does not require oxygen; it is an anaerobic process.

Front

What are the two main stages of cellular respiration?

Back

The two main stages of cellular respiration are glycolysis and oxidative phosphorylation.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain and chemiosmosis.

Front

Where does oxidative phosphorylation take place?

Back

Oxidative phosphorylation takes place in the mitochondrial inner membrane.

Front

What are the products of glycolysis?

Back

The products of glycolysis are 2 pyruvate molecules, 2 ATP molecules, and 2 NADH molecules.

Front

What is the role of the electron transport chain?

Back

The electron transport chain is responsible for transferring electrons from NADH and FADH2 to oxygen, creating a proton gradient that drives ATP synthesis.

Front

What is chemiosmosis?

Back

Chemiosmosis is the process by which ATP is produced as protons flow back across the mitochondrial membrane through ATP synthase.

Front

What factors can denature an enzyme?

Back

Factors that can denature an enzyme include high temperature, low pH, and high pH.
