The statement that enzymes need to be produced by cells in large quantities because they are consumed by the chemical reactions in which they participate is False.
<h3>
How much quantity of enzyme is needed in a Chemical Reaction?</h3>
- Between 1 and 10,000 substrate molecules can be catalyzed by an enzyme every second.
- Due to the fact that they do not change throughout reactions, enzymes are only found in trace levels in cells. and they have a strong affinity for their substrate.
- By lowering the activation energy and activating more molecules, they act as the catalyst to make the process easier to happen. Because the enzyme must react with the substrate, the concentration of the enzyme is crucial in chemical reactions.
- When enzymes locate their intended substrate, they seize them, undergo a transformation, and then move on to the subsequent substrate molecule.

Answer:
the heart
Explanation:
the heart pumps blood through the body
Answer:
A diver on a diving board has kinetic energy equaling zero, but potential energy proportional to the distance between the board and the water. If When the diver dives leaves the platform, he begins losing potential energy because he's nearing the water.
Answer:
Breathing Mechanism of Fish. Fish have gills which help them breathe oxygen directly from water without any need to surface. The fish takes water through its mouth, pushing it over the gills and back out through the gill slits. The oxygen enters the blood vessels after being filtered by the gills.
Explanation:
Fish have Gills
- enzyme pepsin: chemically digests the proteins in the food, breaking down into amino acids
- hydrochloric acid (strong acid): provides an acid environment for pepsin and kills bacteria (food); without this acid, the stomach could not function properly.
