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:
There are three types of neurons are present i. e. sensory neuron, motor neurons and inter neurons.
Explanation:
Sensory neurons are the nerve cells which is responsible for sending the information from the sense organs such as tongue, nose, skin, ears, and eyes to the spinal cord and the brain while the motor neurons are responsible for the transportation of instruction from the brain and spinal cord to the muscles. The inter neuron helps in communication between motor or sensory neuron and the nervous system.
