An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.
How do enzymes affect activation energy?
Enzymes lower the activation energy required for a reaction, allowing the reaction to proceed more quickly.
What is the active site of an enzyme?
The active site is the region on an enzyme where substrate molecules bind and undergo a chemical reaction.
What does it mean for an enzyme to be specific?
Enzymes are specific because they catalyze only one particular reaction or a group of very similar reactions, due to the specific shape of their active site.
What is a substrate in enzyme activity?
A substrate is the molecule upon which an enzyme acts, binding to the enzyme's active site.
