The best description of changes in the rate of an enzyme controlled reaction over time is
It increases, levels off then decreases

A sample of amylase taken from the mouth does not work if placed in a solution of stomach juices, but will work in a solution of small intestine juices. The best explanation of this finding it
Mouth juices have the same pH as small intestine juices
7 of 17
This happens more often between an enzyme and its substrate when the temperature of a solution increases
Collisions

An enzyme controlled reaction goes to completion. What would happen if extra substrate is added after the reaction has finished?
The rate of reaction increases
