Aerobic Respiration R questions

Front

What is aerobic respiration?

Back

Aerobic respiration is a metabolic process in which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the main stages of aerobic respiration?

Back

The main stages of aerobic respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

What is the role of oxygen in aerobic respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

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

Back

The net gain of ATP from one molecule of glucose during aerobic respiration is approximately 30-32 ATP.

Front

What is glycolysis?

Back

Glycolysis is the first stage of aerobic respiration, occurring in the cytoplasm, where glucose is broken down into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

What happens to pyruvate in the presence of oxygen?

Back

In the presence of oxygen, pyruvate is transported into the mitochondria and converted into acetyl-CoA, which enters the Krebs Cycle.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the Citric Acid Cycle, is a series of chemical reactions in the mitochondria that produces ATP, NADH, and FADH2 from acetyl-CoA.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of aerobic respiration, located in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to the production of ATP.

Front

What is the role of NADH and FADH2 in aerobic respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the electron transport chain, where they are used to generate ATP.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process by which ATP is produced in the electron transport chain, using the energy released from electrons as they move through the chain.
