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 glycolysis?

Back

Glycolysis is the first step of cellular respiration where one glucose molecule is split into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the Krebs Cycle?

Back

The Krebs 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

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondria.

Front

What are high energy hydrogen carriers?

Back

High energy hydrogen carriers are molecules that transport electrons and protons during cellular respiration, including NADH and FADH2.

Front

Which molecule is not a high energy hydrogen carrier?

Back

Oxygen is not a high energy hydrogen carrier.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in all living organisms.

Front

What happens to glucose during cellular respiration?

Back

Glucose is broken down into carbon dioxide and water, releasing energy in the form of ATP.

Front

What happens to the carbon atoms in glucose during cellular respiration?

Back

The carbon atoms in glucose are exhaled as CO2.
