C. 38 ATP
<span>In the presence of oxygen, one
glucose molecule has the energy to make up to 38 ATP. The ATP production is
determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9
ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate
and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation
of all the process mentioned that took place. All these process take place under the
cellular function of cellular respiration. </span>
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
