A mutant strain of yeast is able to produce 2 ATP for each glucose molecule digested in the absence of oxygen. What makes this s

train unique is that it does this without producing toxic acids or alcohols. Scientists find high levels of pyruvate in the yeast, and discover that the mutation in this yeast has resulted in the synthesis of a novel enzyme. What is the most likely function of this enzyme?

Answer:

Explanation:

Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.

pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD

The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.

If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme.   <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.

aleksley [76]

Answer:

The Adaptationist Fallacy can prove very costly to biologist who are assuming it wrong according to the function in the environment. Let us have an example of the phenotype of wheat diploid breed that produces non-bearded grains variety, but we cannot assume it as a beneficial phenotype without further extensive research. After research, we came to know that there is also a major hexaploid bearded variety, that produces more number of grains. That's how, the Adaptationist Fallacy may prove fatal if we have assumed diploid as a major beneficial phenotype.

What needs to happen for a solute to dissolve in a particular solvent? A. The attractions between the solute and solvent molecul
Masja [62]

The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent .

Answer: Option A

<u>Explanation:</u>

Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.

It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent.  Separation and mixing up with solvent particles, in general, called as solvatation.
