Why do people go pale when they are cold?

Biology

People get pale when they’re cold because your body is trying to conserve heat. Heat is nessecary to maintain homeostasis, and in a response to this, your blood vessels in your skin constrict (get smaller), so less blood goes to your skin, so that your body can redirect the blood to your core, where all the good stuff is like your organs. 

Blood is what makes our skin a pinkish color, if white people did not have blood, we would look like vampires. When there is less blood in your skin, the pink color goes away and leaves a pale white.

I hope this helps!

Triose phosphate isomerase interconverts dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Mutants of yeast or bacteria
Anettt [7]

Answer:

Explained

Explanation:

Due to lack of of Triose phosphate isomerase cell will be unable to interconvert Dihydroxyacetone to glyceraldehyde 3 phosphate.

And the cells will be able to complete the glycolysis only in the presence of glyceraldehyde 3 phosphate which will generate 2 ATP and hence the net ATP gain during whole process in anaerobic condition will be Zero. This will lead to the dath of the mutant yeast.

a) While in case of aerobic condition, only one molecule of pyruvate will also be able to produce more ATP compared to anaerobic condition by further oxidation which is sufficient for yeast to survive.

b)  the cells will be able to complete the glycolysis only in the presence of glyceraldehyde 3 phosphate which will generate 2 ATP and hence the net ATP gain during whole process in anaerobic condition will be Zero. This will lead to the death of the mutant yeast.
