During aerobic respiration, electrons travel downhill in which sequence?
iris [78.8K]

Answer:

The correct answer will be option-B.

Explanation:

Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.

The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.

The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.

These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.

Thus, Option-B is the correct answer.

The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown

They are therefore expected to produce heterozygous lines.

The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.

A dominant trait is known to mask the expression of other traits.
