Cell Respiration

Front

What is the main function of the mitochondria in cellular respiration?

Back

The mitochondria are the powerhouse of the cell, where aerobic respiration occurs, producing ATP from glucose and oxygen.

Front

Where does the Electron Transport Chain (E.T.C.) occur?

Back

The Electron Transport Chain occurs in the mitochondria inner membrane.

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 pathway does the body primarily use during short bursts of intense exercise, like sprinting?

Back

The body primarily uses anaerobic respiration during short bursts of intense exercise.

Front

Why do oxygen levels decrease during aerobic respiration?

Back

Oxygen levels decrease because oxygen is being used for energy production.

Front

What happens to carbon dioxide levels during exercise?

Back

Carbon dioxide levels increase during exercise due to increased cellular respiration.

Front

What are the main products of photosynthesis that are used in cellular respiration?

Back

The main products of photosynthesis used in cellular respiration are sugar (glucose) and oxygen.

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 role does oxygen play 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 glycolysis and where does it occur?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, occurring in the cytoplasm.
