Cellular Respiration in Detail

Front

What is glycolysis?

Back

Glycolysis is the metabolic process that converts glucose into two molecules of pyruvate, producing a small amount of ATP and NADH in the process.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytosol, which is the fluid outside of the mitochondria.

Front

What is the Link Reaction?

Back

The Link Reaction is the process that converts pyruvate into Acetyl Co-A, which is essential for entering the Krebs Cycle.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, combining with hydrogen to form water.

Front

What is chemiosmosis?

Back

Chemiosmosis is the process by which ATP is produced in the mitochondria as protons flow back into the mitochondrial matrix through ATP synthase.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Link Reaction, the Krebs Cycle, and the electron transport chain.

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 Co-A.

Front

How many ATP molecules are produced during glycolysis?

Back

Glycolysis produces a net gain of 2 ATP molecules per glucose molecule.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient.

Front

What is the significance of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the electron transport chain, where they are used to generate ATP.
