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 is the equation for cellular respiration?

Back

6O₂ + C₆H₁₂O₆ → 6CO₂ + 6H₂O + Energy

Front

How does cellular respiration differ from photosynthesis?

Back

Photosynthesis uses carbon dioxide and produces oxygen, while cellular respiration uses oxygen and produces carbon dioxide.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy.

Front

What happens when a phosphate group is removed from ATP?

Back

When a phosphate group is removed from ATP, a substantial amount of energy is released.

Front

What is lactic acid and why does it accumulate in muscles?

Back

Lactic acid is a byproduct of anaerobic respiration that accumulates in muscles during intense activity, causing soreness.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP, carbon dioxide, and water.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is essential for aerobic respiration as it acts as the final electron acceptor in the electron transport chain.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, producing less energy and resulting in byproducts like lactic acid or ethanol.

Front

What is the significance of the Krebs cycle in cellular respiration?

Back

The Krebs cycle (Citric Acid Cycle) is crucial for breaking down glucose derivatives, producing electron carriers (NADH, FADH₂) for the electron transport chain.
