What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the main purpose of glycolysis?

Back

The main purpose of glycolysis is to break down glucose into pyruvate, producing a small amount of ATP and NADH in the process.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What role does NAD+ play in cellular respiration?

Back

NAD+ acts as an electron carrier, accepting electrons during glycolysis to form NADH, which is used in later stages of cellular respiration.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvate.

Front

What happens to pyruvate after glycolysis?

Back

After glycolysis, pyruvate can enter the mitochondria for further processing in the Krebs cycle or be converted to lactate in anaerobic conditions.

Front

What is the significance of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate, using the proton gradient created during the electron transport chain.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a gradient for ATP production.

Front

How is energy released during cellular respiration?

Back

Energy is released during cellular respiration through the breakdown of glucose, which is converted into ATP, carbon dioxide, and water.
