Cellular Respiration

Front

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 are the main stages of cellular respiration?

Back

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

Front

What is the role of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the electron transport chain, where they are used to produce ATP.

Front

What is the role of FADH2 in cellular respiration?

Back

FADH2 is another electron carrier that donates electrons to the electron transport chain, contributing to ATP production.

Front

What is ATP and why is it important?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the significance of carbon dioxide in cellular respiration?

Back

Carbon dioxide is a byproduct of cellular respiration, produced during the Krebs Cycle and released during the process.

Front

What is the function of ADP in cellular respiration?

Back

ADP (Adenosine Diphosphate) is converted to ATP during cellular respiration, serving as a precursor to the energy currency of the cell.

Front

What is Acetyl CoA and its role in cellular respiration?

Back

Acetyl CoA is a key intermediate in cellular respiration that enters the Krebs Cycle after glycolysis.

Front

What happens during glycolysis?

Back

Glycolysis is the first stage of cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.

Front

What occurs in the Krebs Cycle?

Back

In the Krebs Cycle, Acetyl CoA is oxidized to produce NADH, FADH2, ATP, and carbon dioxide.
