Study Notes
Cellular Respiration
- The primary purpose of cellular respiration is to generate energy for the cell, particularly in the form of ATP (adenosine triphosphate), through the breakdown of glucose and other organic molecules.
Types of Reactions
- Cellular respiration involves catabolic reactions, which break down complex molecules into simpler ones, releasing energy in the process.
Role of Oxygen
- Oxygen plays a crucial role in cellular respiration as it acts as the final electron acceptor in the electron transport chain, allowing the production of ATP through oxidative phosphorylation.
Organisms
- Cellular respiration occurs in all organisms, including prokaryotes, such as bacteria, and eukaryotes, including animals, plants, and fungi.
Reaction Types
- The overall process of cellular respiration involves three main types of reactions: glycolysis, the citric acid cycle, and oxidative phosphorylation.
