Krebs Cycle and Glycolysis Concepts

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 derived from carbohydrates, fats, and proteins.

Front

Where does the Krebs Cycle occur in the cell?

Back

The Krebs Cycle takes place in the mitochondria of eukaryotic cells.

Front

What are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are ATP, NADH, FADH2, and CO2.

Front

What role does NADH play in cellular respiration?

Back

NADH carries high-energy electrons to the electron transport chain, where it helps generate ATP.

Front

What is glycolysis?

Back

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

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the net gain of ATP from glycolysis?

Back

The net gain of ATP from glycolysis is 2 ATP molecules per glucose molecule.

Front

What is the function of the enzyme Rubisco?

Back

Rubisco is the enzyme that catalyzes the first step of the Calvin Cycle, fixing carbon dioxide into an organic molecule.

Front

How does the Krebs Cycle contribute to ATP synthesis?

Back

The Krebs Cycle generates high-energy electrons stored in NADH and FADH2, which are used in the electron transport chain to produce ATP.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process by which ATP is produced using the energy from the electron transport chain and the proton gradient.
