FACTors affecting Respiration
The whole process of respiration is run by enzymes.
Therefore, the same factors that affect enzymes affect respiration.
Therefore, the same factors that affect enzymes affect respiration.
1. Temperature
Too low and respiration slows down. Speeds up as temperature rises. |
2. Oxygen Availability
Sufficient oxygen is required. Only certain tissues can switch to anaerobic (muscle). Other organs can not (brain cells) |
3. Poisons
Respiration is stopped by cyanide. It prevents oxygen from combining with hydrogen and jams up the ETS and Krebs cycle. |
