Aerobic Cellular Respiration (Glycolysis, Krebs Cycle, ETC)

Front

What is aerobic cellular respiration?

Back

Aerobic cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in the presence of oxygen.

Front

What are the three main stages of aerobic cellular respiration?

Back

The three main stages are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain (ETC).

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the main product of glycolysis?

Back

The main product of glycolysis is pyruvate, along with a net gain of 2 ATP and 2 NADH.

Front

What is the Krebs Cycle also known as?

Back

The Krebs Cycle is also known as the Citric Acid Cycle.

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondria of the cell.

Front

How many ATP are produced in one turn of the Krebs Cycle?

Back

One turn of the Krebs Cycle produces 1 ATP, but since each glucose molecule results in two turns, a total of 2 ATP is produced per glucose.

Front

What are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are 2 ATP, 6 NADH, and 2 FADH2 per glucose molecule.

Front

What is the role of the Electron Transport Chain (ETC)?

Back

The Electron Transport Chain (ETC) is responsible for producing the majority of ATP during aerobic respiration by using electrons from NADH and FADH2 to create a proton gradient.

Front

Where does the Electron Transport Chain occur?

Back

The Electron Transport Chain occurs in the inner mitochondrial membrane.
