CELLULAR RESPIRATION

Front

What is cellular respiration?

Back

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

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to release energy stored in glucose for cellular activities.

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

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is produced during glycolysis?

Back

Glycolysis produces 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the Electron Transport Chain, allowing for the production of ATP.

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 is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in products like lactic acid or ethanol.

Front

How does cellular respiration relate to photosynthesis?

Back

Cellular respiration and photosynthesis are interconnected; photosynthesis converts light energy into chemical energy (glucose), which is then used in cellular respiration to release energy.
