b. can be bonded together to construct dna molecules
c. are made up of the glucose monomer
d. are monomers that can be made into large polymer chains

2. enzymes are proteins that speed up reactions by (2 points)
a. providing an additional energy source
b. supplying additional molecules for the reaction
c. removing inhibitors that slow down reactions
d. lowering the amount of energy required

1. Carbohydrates and fats both - can be used as an energy source by organisms.

Carbohydrates provides quick energy while fats are stored energy. If there is no sufficient carbohydrates to provide energy, then the stored fats come to use.

2. Enzymes are proteins that speed up reactions by - Lowering the amount of energy required.

Enzymes are proteins that speed up reactions by reducing the activation energy needed to get them to work. They play a vital role in bodily functions like digestion.
