Study Notes
Cellular Respiration and Energy
- Anaerobic respiration produces acid in your muscles after a hard workout, leading to fatigue.
- A person can survive without eating for several weeks, depending on factors like body fat reserves and physical activity.
Energy Sources
- Glucose is the main source of energy for cellular respiration, which powers the body's functions.
- Oxygen is required for efficient fuel burning in a sports car, just like in the human body.
Energy Consumption
- The cells of your brain burn approximately 12-13 grams of glucose each day, accounting for a significant portion of the body's energy expenditure.
