3.2 - Cellular Respiration

Cellular respiration is the process that our cells use to convert sugar (glucose) into energy (ATP).

The main purpose of cellular respiration is to produce energy.

ATP (Adenosine Triphosphate) is the energy molecule produced during cellular respiration.

The waste gas given off by cellular respiration is carbon dioxide.

Cellular respiration occurs in the mitochondria.

The chemical equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

The two main stages of cellular respiration are glycolysis and the Krebs cycle (Citric Acid Cycle).

Glycolysis is the first step of cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP.

Oxygen is used in the electron transport chain to help produce ATP and is essential for aerobic respiration.

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