Why can mixing of oxygenated and deoxygenated blood reduce energy availability in the body?
Answer and explanation
Correct answer: Less oxygen will reach cells
Aerobic respiration in cells uses oxygen to oxidise glucose and release a large amount of usable energy. If oxygenated blood mixes with deoxygenated blood, the resulting blood has a lower oxygen concentration than fully oxygenated blood. Less oxygen reaches tissues, so aerobic energy production can fall. Hence option A is correct; the other choices concern unrelated digestive or plant functions.
