This is the term that describes the amount of energy that needs to be absorbed for a chemical reaction to start.
What is activation energy?
200
This is the aspect of a chemical reaction that an enzyme affects.
What is reaction rate?
300
This type of bond is made between the electrical force between oppositely charged ions.
What is ionic bond?
300
This is the term that describes the attraction among molecules of a substance like water.

What is that it dissolves and transports substances?
500
This is the term for the monomer that makes up carbohydrates.
What are monosaccharides?
500
This is the term that describes the amount of energy that will break a bond between two atoms.
What is bond energy?
