4.21 Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the main energy molecule produced during cellular respiration?

Back

The main energy molecule produced is ATP (adenosine triphosphate).

Front

What are the two main types of cellular respiration?

Back

The two main types are aerobic respiration (requires oxygen) and anaerobic respiration (does not require oxygen).

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used to help break down glucose to release energy during aerobic respiration.

Front

What is produced as a waste product of cellular respiration?

Back

Carbon dioxide and water are produced as waste products.

Front

What is the significance of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including muscle contraction, nerve impulse propagation, and biosynthesis.

Front

What happens to cells during anaerobic respiration?

Back

During anaerobic respiration, cells generate energy without oxygen, producing less ATP and byproducts like lactic acid or ethanol.

Front

What is anemia?

Back

Anemia is a condition where there is a deficiency of red blood cells or hemoglobin, leading to reduced oxygen transport in the body.

Front

What are sickle-shaped cells?

Back

Sickle-shaped cells are abnormally shaped red blood cells that can block blood flow and cause pain and complications.

Front

How does exercise affect cellular respiration?

Back

Exercise increases the demand for energy, leading to increased rates of cellular respiration and oxygen consumption.
