Cellular Respiration is a fundamental metabolic process that provides cells with energy for functioning. This complex process involves both aerobic respiration and anaerobic pathways, breaking down organic compounds to release energy stored in ATP molecules.
Key points:
- Glucose is the primary substrate, though fats and proteins can also be used
- Aerobic respiration yields 30-32 ATP molecules
- Anaerobic processes produce less energy (2 ATP for fermentation)
- Process efficiency depends on organism type and tissue requirements
- Environmental factors influence respiration intensity
Definition: Cellular respiration is a catabolic process that breaks down complex organic compounds into simpler molecules while releasing energy stored in ATP.
