Enzymes

The term for a biological catalyst

• Carbon-compounsa

• sugars

• enzymes

Energy needed to get a reaction started

• catalytic energy

• kinetic energy

• covalent energy

• activation energy

How do enzymes affect chemical reactions?

• they prevent reactions from occuring

• providing energy directly to the reaction

• decreasing the amount of energy to get the reaction started
