Cellular respiration is the process by which cells generate usable energy in the form of ATP, essential for survival, growth, reproduction, and function of cells.
Types of Cellular Respiration
Aerobic Respiration
Requires oxygen.
Occurs in the mitochondria.
Comprises three stages: Glycolysis, Krebs Cycle, and Electron Transport Chain.
Yields the highest amount of ATP.
Influenced by oxygen concentration, glucose availability, and temperature.
Anaerobic Respiration
Does not require oxygen.
Conducted by some bacteria and microbes in oxygen-free environments.
Some organisms like yeast can perform anaerobic respiration even in oxygen presence.
Key Concepts
Process of Aerobic Respiration
A detailed pathway consisting of Glycolysis, Krebs Cycle, and Electron Transport Chain.
High ATP yield and occurs when oxygen is present.
Anaerobic Respiration
Occurs in the absence of oxygen.
Less efficient ATP production compared to aerobic respiration.
Common in certain bacteria, yeast, and muscle cells under strenuous activity.
Factors Affecting Aerobic Respiration
Oxygen availability.
Glucose levels.
Temperature and environmental conditions.
