Cellular Respiration

Front

Where does cellular respiration occur in a cell?

Back

Cellular respiration occurs in the cytoplasm and mitochondria.

Front

What is the main purpose of glycolysis in cellular respiration?

Back

The main purpose of glycolysis is to generate ATP and NADH.

Front

How many ATP molecules are produced from one molecule of glucose during glycolysis?

Back

2 ATP are produced from one molecule of glucose during glycolysis.

Front

What are the reactants needed for cellular respiration?

Back

The reactants needed for cellular respiration are glucose and oxygen.

Front

During glycolysis, what happens to electrons released from glucose?

Back

Electrons released from glucose attach to NAD to make NADH, which transfers the electrons to the ETC in the inner mitochondrial membrane.

Front

What is the overall equation for cellular respiration?

Back

The overall equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is the role of mitochondria in cellular respiration?

Back

Mitochondria are the sites of the Krebs cycle and oxidative phosphorylation, where most ATP is produced.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing ATP and NADH.

Front

What is the Krebs cycle?

Back

The Krebs 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 process of ATP production that occurs in the mitochondria, using the electron transport chain and chemiosmosis.
