Aerobic Respiration

Front

What is aerobic respiration?

Back

Aerobic respiration is a metabolic process that uses oxygen to convert glucose into energy (ATP), carbon dioxide, and water.

Front

What is the main purpose of the Electron Transport Chain (ETC)?

Back

The main purpose of the ETC is to produce ATP through oxidative phosphorylation by transferring electrons and pumping protons (H+) across the mitochondrial membrane.

Front

What enzyme in the ETC is responsible for generating ATP molecules?

Back

ATP synthase.

Front

What is the function of the intermembrane space of the mitochondria?

Back

The intermembrane space accumulates H+ ions quickly, creating a proton gradient that drives ATP synthesis.

Front

What are cristae in the mitochondria?

Back

Cristae are the folds of the inner mitochondrial membrane that increase the surface area available for ATP synthesis.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a net gain of 2 ATP and 2 NADH.

Front

What is the net gain of ATP from glycolysis?

Back

2 ATP.

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.

Front

Which step of aerobic cellular respiration produces the most ATP?

Back

The Electron Transport Chain.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the mitochondria, involving the ETC and ATP synthase.
