What is the relationship between amount of hemoglobin in the blood and amount of ATP released in the human body?
Relationship between amount of haemoglobin and ATP released
Haemoglobin in the blood transports oxygen from the lungs to body cells.
Oxygen is essential for aerobic respiration, during which food (glucose) is completely broken down to release ATP (energy).
Therefore:
More haemoglobin → more oxygen transported → higher rate of aerobic respiration → more ATP released.
Less haemoglobin → less oxygen supply → reduced aerobic respiration → less ATP released (may lead to fatigue).
