Question

Suppose two students were experimenting with yeast to study cellular respiration. One student found glucose to be the most efficiently consumed sugar by yeast, whereas the other student found maltose to be the most efficiently consumed sugar by yeast. Which of One the following could explain the results?
a. Neither of the two answer choices could explain the results.
b. Organisms have varying optimal conditions at which they work the best. The students may have used different temperatures or ph levels for their individual experiments
c. Either of the two answer choices could explain the results.
d. Different organisms process fod sources differently due to the availability of food and other environmental conditions. The students may have used different yeast strains.

Answer 1

Answer:

The correct answer is statement c.

Explanation:

It is known that different strains of yeast may possess a differential choice for the molecules of sugars to be consumed. Like Saccharomyces cerevisiae strain may ferment sucrose, glucose, and raffinose, and other strain like Saccharomyces rouxii can ferment maltose and glucose, and the physical condition may change the consumption of sugar such that the strains of yeast at distinct temperatures may exhibit different efficacy of glucose consumption.
