a ____________ speeds up a chemical reaction. enzymes are an example of this. * 1 point\nsubstrate\ncatalyst\ntemperature\nactive site
Answer
Brief Explanations:
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. Enzymes are biological catalysts. A substrate is the reactant on which an enzyme acts. Temperature can affect reaction - rate but is not a substance like a catalyst. The active site is the part of an enzyme where the substrate binds.
