Question

Arrange the sequence of events for the overall mitochondrial respiratory assembly in the correct order.1) Coenzyme Q-cytochrome c reductase passes electrons to cytochrome c.2) Coenzyme Q releases its electrons to complex III.3) Cytochrome oxidase catalyzes the reduction of O2 to water.4) Succinate, through complex II, and NADH, via complex I, release electrons to coenzyme Q.A. 4, 1, 3, 2B. 4, 3, 1, 2C. 4, 1, 2, 3D. 4, 2, 1, 3

Answer 1

D. 4, 2, 1, 3

Step-by-step explanation:

Succinate, through complex II, and NADH, via complex I, release electrons to coenzyme Q ⇒⇒⇒ Coenzyme Q releases its electrons to complex III ⇒⇒⇒Coenzyme Q-cytochrome c reductase passes electrons to cytochrome ⇒⇒⇒⇒Cytochrome oxidase catalyzes the reduction of O2 to water
