A is the right answer because it is.
Answer:
- They allow for more collisions of molecules (enzymes + substrates)
- They lower the amount of activation energy needed to complete the reaction.
- They speed up chemical reactions to form more products
Explanation:
Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).
Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
Emigrated means they exited so due to the high amounts of pollution all the animals left which cause a population decrease
The leading is replicated continuously for the entire length of the chromosome, while the lagging strand is replicated in pieces.
