Triose phosphate isomerase interconverts dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Mutants of yeast or bacteria

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.

Accumulation flooding occurs because the ground is completely _____ and there is no longer a zone of _______.
maw [93]

Answer:

Accumulation flooding occurs because the ground is completely filled with water and there is no longer a zone of dry land.

Explanation:

Flood is the overflow of water on the land which is usually dry throughout the year. It occurs when more water comes in the river due to rainfall or breaking of dam. But mostly flood occurs, due to melting of ice on the poles because of global warming. Global warming refers to the increase in average temperature due to presence of greenhouse gases such as carbondioxode, methane and water vapors etc in the atmosphere.

Anna11 [10]

Pure chlorine is an example of an element.

An element is a chemical substance that cannot be broken down into simpler components in a chemical reaction or by any chemical means, and is made up of atoms that all have the same number of protons. Pure chlorine is an example of an element because it contains only one kind of an atom. Chlorine is a toxic, green, gaseous chemical element. Chlorine is a halogen, has an atomic number of 17, symbol Cl and is found in group 17 in the periodic table. Chlorine is highly reactive and a strong oxidizing and disinfecting agent.
