Question

How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) They allow for more collisions of molecules (enzymes + substrates) They raise the amount of activation energy needed to complete the reaction They lower the amount of activation energy needed to complete the reaction They speed up chemical reactions to form more products

Answer 1

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.
