Aerobic respiration
Biology · Secondary 3 · Medium · Aerobic respiration
During exercise at high altitude, a person’s body produces more red blood cells over several weeks. How does this adaptation help during aerobic respiration in muscles?
- More oxygen is transported to muscles, so more energy is released by aerobic respiration.
- Less oxygen reaches muscles, so they rely more on anaerobic respiration.
- Carbon dioxide transport decreases, so breathing rate can fall.
- Blood becomes thicker so the heart works less during exercise.
