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

Front

What happens to pyruvate after glycolysis in aerobic respiration?

Back

After glycolysis, pyruvate is transported into the mitochondria, where it is converted into acetyl-CoA before entering 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 generates ATP, NADH, and FADH2 by oxidizing acetyl-CoA.

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 from NADH and FADH2 to oxygen, creating a proton gradient that drives ATP synthesis.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the electron transport chain, where the energy from electrons is used to pump protons across the mitochondrial membrane.

Front

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

Back

NADH and FADH2 are electron carriers that transport high-energy electrons to the electron transport chain, where their energy is used to produce ATP.
