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.
Answer:
Electron transport Chain (Oxidative phosphorylation)
Explanation:
Cellular respiration can be defined as the process that involves the breakdown of glucose molecules into CO2 and H2O to generate energy inform of Adenosine Triphosphate (ATP). Also, cellular respiration usually takes place in the cells of an organism by converting biochemical energy present nutrients into Adenosine Triphosphate. Furthermore, it takes place in three stages which includes: glycolysis, TCA cycle and Electron transport (Oxidative phosphorylation). Thus, oxidative phosphorylation is the final stage of aerobic cellular respiration that produces maximum ATPs.
A sperm and egg combine to make a zygote. (or fertilized egg)
So, the answer would be "A".
