Which of the following would increase the rate of an enzyme-catalyzed reaction?
Decreasing enzyme, decreasing substrate, decreasing cofactors
Decreasing enzyme, decreasing inhibitors, decreasing cofactors
Increasing enzyme, decreasing substrate, decreasing cofactors
Increasing enzyme, decreasing inhibitors, increasing cofactors
Answer: Increasing enzyme, decreasing inhibitors, increasing cofactors
Explanation:
Why? Well, we know that increasing how much enzyme is available is a good method to speed up the rate of an enzyme catalyzed reaction because we have MORE enzymes to deal with the substrates. We also know that cofactors are essential for widening the range of substrates an enzyme can catalyze. Cofactors also stabilize charge, so the substrate can fit into the binding site better.

What is the difference between bunnies', rabbits, and hares?
Answer:
Hares tend to be larger than rabbits, with longer hind legs and longer ears with black markings. While rabbits' fur stays the same color year-round, hares change color from brown or gray in the summer to white in the winter. Rabbits make their homes in burrows underground, while hares make nests above ground. The word bunny is often used to describe a baby rabbit; however, there is actually a different name for this. Finally, you can call a young child Bunny as a term of endearment. A bunny and a rabbit really are just two names for the same animal. A hare, on the other hand, is a completely different species. They may look similar, but hares are typically bigger than rabbits and have very different living and breeding habits.
