4. In the fermentation activity, how will you determine if the yeast is performing fermentation?
Scrat [10]

Answer:

Without oxygen present, fermentation occurs. The product of fermentation is a smaller amount of ATP and alcohol (ethanol is a form of alcohol). You can see the products in the graph of sample B. Sample B was not given oxygen (anaerobic) and therefore performed fermentation.

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.

What is some things the same about mars and Saturn
cluponka [151]

Answer:

One possible similarity, though, is rings. Saturn is encircled by wide, beautiful rings. Mars doesn’t have any rings today, but it could have had them in the distant past — and might again millions of years in the future.
