? ? https://atinviowurgadu/dzielcontent/1SS6SSNewContent/2317157gNew Suppose two students were experimenting with yeast to study cellular respiration. 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? Neither of the two answer choices could explain the results. 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.

Explanation / Answer

Question No.1             Answer is option D

Explanation:-Glucose is better than maltose as a respiratory substrate of yeast for their cellular respiration because glucose as a monosaccharide (C6H12O6) can easily be broken down by yeast; however, maltose is a disaccharide (consists of two units of glucose; C12H22O11). So if both glucose and maltose are available for cellular respiration for yeast, first of all, glucose will be utilized and then maltose.

Question No.2             Answer is option B

Explanation:-

Monosaccharide         [C6H12O6 ------- C2H5OH + 2Co2 + 2ATP]

            Disaccharide (2 X Monosaccharide)

                                                2 X [C6H12O6 ------- C2H5OH + 2Co2 + 2ATP]

So, 4 molecules of CO2 will be produced after breakdown of a disaccharide however, 2 molecules of CO2 will be generated by monosaccharide breakdown.

Question No.3             Answer is option C

Explanation:-Yeast converts monosaccharide into alcohol and CO2. The alcohol can be used for beer production and as ethanol for fuel; however generated CO2 can be used for bread production.
