A student says, “Anaerobic respiration transfers no energy because oxygen is absent.” Which correction is most accurate?
It transfers more energy because glucose is completely oxidised without oxygen
It transfers equal energy because both pathways begin with one glucose molecule
It transfers less energy because glucose is incompletely oxidised without oxygen
It transfers no energy because lactic acid stores none of the glucose energy
