[First Review of Enzyme Reactions]

4. Why does enzyme activity increase as temperatures are increased?

A) There is more substrate available, so the enzymes have a greater chance of meeting them and reacting.

B) Enzymes grow more active sites as temperatures increase, so reactions can go much faster.

C) The substrate and enzyme move faster so there is a greater chance they will collide and react.

D) The substrate and enzyme are more happy at warmer temperatures so they are more likely to react.
