AP Biology - 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

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

What is the main product of cellular respiration?

Back

The main product of cellular respiration is adenosine triphosphate (ATP), which is used as energy by cells.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the role of Acetyl-CoA in cellular respiration?

Back

Acetyl-CoA is a key molecule that enters the Krebs Cycle after pyruvate is converted, playing a crucial role in energy production.

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

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP.

Front

What is ATP?

Back

Adenosine triphosphate (ATP) is the energy currency of the cell, providing energy for various cellular processes.

Front

What happens during the phosphorylation of ADP?

Back

During phosphorylation, ADP combines with a phosphate group to form ATP, storing energy for cellular use.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy and byproducts like lactic acid or ethanol.
