Glycolysis

Front

What is glycolysis?

Back

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

Front

What is the primary reactant in glycolysis?

Back

Glucose is the primary reactant in glycolysis.

Front

How many ATP molecules are used in the energy investment phase of glycolysis?

Back

2 ATP molecules are used in the energy investment phase of glycolysis.

Front

What are the end products of glycolysis?

Back

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

Front

What role does NAD+ play in glycolysis?

Back

NAD+ acts as an electron carrier, accepting high-energy electrons to form NADH.

Front

Is oxygen required for glycolysis to occur?

Back

No, glycolysis does not require oxygen; it can occur in both aerobic and anaerobic conditions.

Front

What is the net gain of ATP from one molecule of glucose during glycolysis?

Back

The net gain of ATP from one molecule of glucose during glycolysis is 2 ATP.

Front

What is the significance of glycolysis in cellular respiration?

Back

Glycolysis is the first step in cellular respiration, providing energy and substrates for further metabolic processes.

Front

What happens to pyruvate after glycolysis in the presence of oxygen?

Back

In the presence of oxygen, pyruvate is converted into acetyl-CoA and enters the Krebs cycle.

Front

What is the energy yield of glycolysis in terms of NADH?

Back

Glycolysis produces 2 NADH molecules per glucose molecule.
