Answer:
6 giraffes
Explanation:
If an area can provide 450 pounds of food for the giraffes and the giraffes eat 75 pounds of food per day, you can divide:
450 by 75= 6
6 giraffes is the capacity for that area
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.
