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.
The determining factors are; climate, environment, and Human Activity.
P.S.: try those...lmk if they are right ;)

Answer:
FRONTAL LOBE
Explanation:
The frontal lobe can be located at the anterior part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe functions and helps in coordination of reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.
Let say for example Kyle is my friend who was a victim of an accident.
Before the accident, he was industrious and well liked BUT after the accident, he is profane, impetuous, and incapable of working toward a goal.
Such changes in personality would be consistent with loss of impulse control which is a significant frontal lobe function. With connections between the planning functions of the frontal lobe and the emotional processes of the limbic system severed, Kyle had difficulty controlling his emotional impulses, attitudes and abiiity of working towards his goals.
