Explanation Explanation for the correct answer: Option (b) is given as, the superior colliculus. The superior colliculus is a multi-sensory and layered structure. Movements of the iris and accommodation of the eye are controlled by the superior colliculus. The parasympathetic nerves for the pupillary light reflex are stimulated by the superior colliculus region of the brain. Therefore, option (b) is correct. Explanation for the incorrect answer: Option (a) is given as, the lateral geniculate...

One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?
