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.
oxygen flow is low and his lungs do not have a lot of capacity
<span>well i take this test before and the correct answer is :A They produce food by photosynthesis</span>
Grapes Maybe?? Sorry I dunno, I just hear purple.
Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.
