Answer:
The correct answer is the formation of pyruvate from glucose willl be energetically less favorable.
Explanation:
According to the question matunt yeast has a shorter glycolytic pathay catalysing a follwing reaction
Glyceraldehyde-3-phosphate+H2O+NAD+ = 3-phosphoglycerate
So in the mutatant the formation of 1,3- bisphosphoglycerate is not occurring.The glyceraldehyde-3-phosphate is directly converted into 3-phosphoglycerate.
As a result the substrate level phosphorylation step that deals with formation of 3-phosphoglycerate from 1,3 bisphosphoglycerate is not occurring.
From this point of view it can be said that less energy will be formed in the mutant during glycolysis than that of normal one.
So the formation of pyruvate from glucose will be energetically less favorable.
Answer: Option E) None of the above is true; this enzyme could bind none of these.
Explanation:
Lactose is a dissacharide composed of glucose and galactose. Hence, the enzyme lactase break down lactose into its simple sugar constituents.
However, lactase cannot bind nor break down amino acids, starch (with only glucose units) or sucrose (with two glucose units) because their constituent molecules differ markedly from that of lactose.
Thus, the enzyme lactase could bind with none of the options provided except lactose
Yes it occurs naturally on everyone :)
<h3><u>Answer;</u></h3>
D) it lacks a nuclear membrane and resides inside the nucleus
<h3><u>Explanation;</u></h3>
- <em><u>Nucleolus is a type of cell organelle that is located in the nucleus of an tom. </u></em>Nucleus is the control center of an atom, it controls all the cellular activities taking place in the cell.
- <em><u>Nucleolus is made up of ribosomal RNA and proteins. The main function of the nucleolus is to assemble or formation of ribosomes. </u></em>Ribosomes are cell organelles that are found in the cytoplasm either attached on the endoplasmic reticulum or freely floating in the cytoplasm, where the process of protein synthesis takes place.
