Cell Respiration

Front

What is cell respiration?

Back

Cell respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does the electron transport chain occur?

Back

The electron transport chain occurs in the mitochondria inner membrane.

Front

What is the role of oxygen in aerobic respiration?

Back

Oxygen is used to help convert glucose into energy, and its levels decrease as it is consumed.

Front

Define aerobic respiration.

Back

Aerobic respiration is a type of cellular respiration that requires oxygen to produce energy.

Front

What are the main reactants in cell respiration?

Back

The main reactants in cell respiration are oxygen and sugar (glucose).

Front

What is glycolysis?

Back

Glycolysis is the first step in cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

What happens after glycolysis if oxygen is present?

Back

If oxygen is present, the process continues to the Kreb's Cycle.

Front

What is the Kreb's Cycle?

Back

The Kreb's Cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is produced during the electron transport chain?

Back

The electron transport chain produces ATP and water as byproducts.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs when oxygen is scarce, converting glucose into lactic acid and energy.
