AP Bio Insta-Review Topic 3.6*: Cellular Respiration

Front

What is cellular respiration?

Back

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

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are the three main stages of cellular respiration?

Back

The three main stages are Glycolysis, the Krebs Cycle, and the Electron Transport Chain.

Front

What is the main purpose of the Krebs Cycle?

Back

The main purpose of the Krebs Cycle is to produce electron carriers (NADH and FADH2) that are used in the Electron Transport Chain.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the Electron Transport Chain, allowing for the production of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of ATP without oxygen, typically resulting in lactic acid or ethanol.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is ATP Synthase?

Back

ATP Synthase is an enzyme located in the inner mitochondrial membrane that synthesizes ATP from ADP and inorganic phosphate.

Front

What is the intermembrane space in mitochondria?

Back

The intermembrane space is the space between the inner and outer mitochondrial membranes where protons are pumped during the Electron Transport Chain.

Front

What is the function of the electron transport chain?

Back

The electron transport chain transfers electrons through a series of proteins, creating a proton gradient that drives ATP synthesis.
