True or False: Metabolic reactions will destroy an enzyme. Thus every chemical reaction in your body requires a brand new enzyme.
False! Enzymes are not "used up" by the chemical reactions they facilitate.

Okay!
True or False: Lactose is a disaccharide sugar that can be oxidized by an enzyme called Sucrase.
False! Enzymes are substrate specific. Lactose will not fit into Sucrase. Only Sucrose is oxidized by Sucrase.

Catabolism is ____________.
The breaking of chemical bonds to produce smaller molecules from larger ones. (Digestion)

In biochemistry a substrate is _______________.
the chemical, or reactant, that goes into an enzyme.

Okay!
If this chemical reaction requires an enzyme what would another name for reactants be?
The substrate or substrates.

Okay!
Anabolism is ____________.
the building of larger molecules by forming chemical bonds.

Describe this chemical. Is it a monosaccharide or a disaccharide?
Sucrose is a disaccharide. It is essentially table sugar. It is considered to be a nutrient.
Oops!
Okay!
A is _________
the enzyme's active site. The substrate fits into it.
Oops!
Okay!
Sucrase is __________ that can ___________.
Sucrase is an enzyme that can catabolize (or break down) sucrose (table sugar).

Okay!
Why do a lot of biological chemicals need enzymes? What takes place inside of an enzyme?
The inside of an enzyme provides the perfect environment for a chemical reaction to take place because activation energy is lowered.

Okay!
What are cofactors and coenzymes? Why are they needed?
Cofactors and Coenzymes are chemicals, such as Vitamin C, or Iron, that fit into an enzyme and make it work better.
