Study Notes
Cellular Respiration Overview
- Primary purpose: Convert biochemical energy from nutrients into adenosine triphosphate (ATP), the energy currency for cellular activities.
- Waste products: Carbon dioxide (CO2) and water (H2O) are primarily produced during cellular respiration.
Organisms Involved
- Cellular respiration occurs in a wide range of organisms, including:
- Animals
- Plants
- Fungi
- Many microorganisms
Types of Reactions
- Cellular respiration involves two main types of reactions:
- Oxidation-reduction (redox) reactions: Transfer of electrons between molecules, critical for energy production.
- Catabolic reactions: Breakdown of complex molecules to release energy.
Biochemical Steps
- Some biochemical steps in cellular respiration are categorized as:
- Exergonic reactions: Release energy as chemical bonds are broken.
- Endergonic reactions: Require energy input for the formation of bonds during the synthesis of ATP.
Redox Reactions
- Role of redox reactions: Facilitate electron transfer, where:
- Oxidation refers to loss of electrons from a substance.
- Reduction refers to the gain of electrons by a substance, contributing to energy conversion.
Inorganic Electron Acceptor
- Inorganic electron acceptor in cellular respiration: Oxygen (O2) primarily serves as the final electron acceptor in aerobic respiration, leading to the formation of water.
