Cellular Respiration AP

Front

What is cellular respiration?

Back

Cellular respiration is a biochemical process in which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the end product of glycolysis?

Back

The end products of glycolysis are 2 molecules of pyruvate, 2 molecules of ATP, and 2 molecules of NADH.

Front

What is the role of Acetyl CoA in cellular respiration?

Back

Acetyl CoA is the molecule that enters the Krebs Cycle, derived from pyruvate after glycolysis.

Front

What is the Krebs Cycle also known as?

Back

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

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 is the function of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the Electron Transport Chain.

Front

Where does the Electron Transport Chain occur?

Back

The Electron Transport Chain occurs in the inner mitochondrial membrane.

Front

What is the primary role of oxygen in cellular respiration?

Back

The primary role of oxygen in cellular respiration is to act as an acceptor for electrons and hydrogen, forming water.
