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 byproducts of cellular respiration?

Back

The main byproducts of cellular respiration are carbon dioxide (CO2), water (H2O), and heat.

Front

Which molecule is NOT a byproduct of cellular respiration?

Back

ATP is not a byproduct; it is the main product of cellular respiration.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Kreb's cycle?

Back

The Kreb's cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.

Front

How many ATP are produced in anaerobic respiration?

Back

Anaerobic respiration yields about 2 ATP per glucose molecule.

Front

How many ATP are produced in aerobic respiration?

Back

Aerobic respiration yields about 38 ATP per glucose molecule.

Front

What does it mean when ADP is phosphorylated?

Back

When ADP is phosphorylated, it means that ADP is being converted into ATP, storing energy.

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.
