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
Free_Kalibri [48]

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 all-or-none phenomenon as applied to nerve conduction states that the whole nerve cell must be stimulated for conduction to
Sphinxa [80]

Answer:True

Explanation:

Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.

Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.

THIS IS ALL OR NONE PRINCIPLE

The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.

What is the source of oxygen in the epipelagic zone?
Rudiy27

The correct answer is (B) Photosynthesis and diffusion from the air

Dissolved oxygen enters the water from photosynthesis and through air. The The aeration of water can be caused by wind. From the air oxygen diffuse into the water and gets mixed in the it through circulation. The oxygen is also produced as a waste product of photosynthesis from blue-green algae, phytoplankton, etc which is added in water.
