Which cellular process results in the most significant production of ATP? a. oxidative phosphorylation b. Krebs cycle c. glycolysis d. fermentation

Answers

Answer:

Answer is A . Oxidative phosphorylation.

Explanation:

A mechanism or metabolic  pathway that produce adenosine triphosphate, ATP, by using the energy produced during the oxidation of nutrients is described as oxidative phosphorylation. This metabolic pathway is known to be the pathway for the production of adenosine triphosphate, ATP in living organisms, i.e, in plants and animals.

It was discovered that , oxidative phosphorylation takes place in the mitochondria , specifically during aerobic respiration.

Note that, aerobic respiration is the type of respiration that occur in the absence of oxygen.

Artificial selection was used on corn to produce a single strain of corn with increased growth rates and greater resistance to a fungus. Although farmers have continued to select for these traits, the productivity of this strain is no longer increasing. This suggests that:_____________.

Answers

Answer:

The natural variation for these traits has been eliminated

Explanation:

Natural variation occurs when there's a variation in the genetic and epigenetic material of a population (corn), in this case, caused by artificial selection. Since this variation is not happening anymore, this means that the genetic material is not being transmitted any longer and therefore the natural variation has been eliminated.
