Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is a metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

The three main stages 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 product of glycolysis is 2 pyruvates.

Front

What is the role of NAD+ in cellular respiration?

Back

NAD+ acts as an electron carrier, accepting electrons during glycolysis and the Krebs Cycle to form NADH.

Front

What happens during the Krebs Cycle?

Back

During the Krebs Cycle, acetyl-CoA is oxidized to produce ATP, NADH, FADH2, and carbon dioxide.

Front

What is the main purpose of the Electron Transport Chain?

Back

The main purpose of the Electron Transport Chain is to produce ATP through oxidative phosphorylation.

Front

What is fermentation and when does it occur?

Back

Fermentation is an anaerobic process that allows glycolysis to continue by regenerating NAD+ in the absence of oxygen.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is a type of anaerobic respiration that occurs in muscle cells, producing lactic acid and ATP.

Front

What is the chemical formula for glucose?

Back

The chemical formula for glucose is C6H12O6.
