Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of the presence of a new enzyme catalyzing th
Ganezh [65]

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.

Describe the connection between a mountain range and a rain shadow. This illustration shows the cross section of a segment of mo
Soloha48 [4]
Wind and moist air are drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".

Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop.

Powered by. A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked.
