Multicellular organisms use different types of cells to function not just one cell. If cells grew larger that cell would be more demanding.
The human body needs it for reproduction
Answer: I think it’s Enzymes are used up after catalyzing a reaction enzymes may only be used once. Explanation: Hope this helped
The answer is; A
The active site of the enzyme is bound by a substrate and probably the enzyme catalyzes a hydrolysis reaction. The poison mimics the substrate and competes with the substrate for the active site of the enzyme. The poison may bind permanently to the enzyme rendering the enzyme unavailable for other substrates. This could make a particular biochemical reaction, in which the enzyme is involved, to reduce drastically hence threatening life.
