2
Enzymes are proteins that speed up chemical reactions in the body.
3
Each enzyme has only one specific reaction it can perform.
4
Yes, the same enzyme molecule can be used over and over
5
The shape of an enzyme determines its function.
6
Denaturing is when extreme pH or high temperature change the shape of the enzyme making it less or ineffective.
8
An enzyme align 2 molecules, enabling them to bond and form a larger molecule.
10
Enzymes can only bond with molecules that physically fit
12
A single enzyme reacts with several of the same molecule, creating a chain of that molecule
14
An enzyme can be denatured by temperature or pH extreme. The shape of the enzyme is changed and becomes inactive.
15
The process of denaturing is NOT reversible. Once an enzyme is denatured it will never be effective again
16
The enzyme actually changes its shape and will not fit with the substrate it was meant for.
18
The substrate is the “thing” the enzyme is acting upon. The product is what is produced from the enzyme and substrate reaction. Area that the substrate and enzyme meet is know as the active site.
19
Coenzymes help make a fit between the enzyme and coenzyme when necessary. Coenzymes are made of vitamins and minerals
20
An inhibitor blocks/prevents a reaction from happening.
21
They prevent reactions from happening that are vital to life.
23
The higher the concentration of the substrate the slower the reaction. The lower the concentration of the substrate the faster the reaction.
24
The higher the concentration of an enzyme, the faster the reaction. The lower the concentration of an enzyme, the slower the reaction.
25
The enzyme prefix is usually after the substrate it acts upon. The suffix or ending is usually “ase” Example: Lipase is an enzyme because it ends in “ase” We know it acts upon lipids because it starts in “lip”
