Ex 39A Digestive Enzymes. Energy Transfer in Chemical Reactions Forming new bonds can either release or absorb energy Chemical reactions usually involve.
A catalyst Is a chemical agent that speeds up a reaction without being consumed by the reaction An enzyme is an organic catalyst Enzymes are proteins.
