NOT all, but most Enzymes are Proteins
Example: Ribozyme (splits RNA to mRNA, but does not have a protein part)
Basically, everything will affect the function of an enzyme.

Anything that requires ANY type of work, is started by Enzymes (Biological Catalysts) They limit activation energy
Enzymes either put multiple substrates together to make one product.
OR
Enzymes break apart a substrate into multiple products.

Substrate:
The thing the enzyme works with

Active Site:
The place the Enzyme and substrate connect
It is usually a HYDROGEN BOND
Has a unique shape and size and can have chemical charges that attract ions in the substrate

Co-Factor:
An inorganic substance that HELPS with the enzyme reaction, it is usually METAL IONS, like zinc and Fe

Induced fit:

Sometimes the enzyme will bend around the substrate, for a tighter grip

Products released: The enzyme can either break apart a substrate or
Enzymes can be Reused and aren’t changed after a reaction.

Competitive Inhibitor:
Something that binds to the active site, so the substrate can’t go into the enzyme.

Noncompetitive inhibitor:
Something that binds to the allosteric site, which changes the shape of the active site, so the substrate can’t connect.

Enzyme Naming:
The enzyme is named after its substrate AKA what it does AND ends in -ase.
Ex.
Lipase —-> Breaks down lipids/fat

Activation Energy:
The energy required for a reaction to happen.
Enzymes help with lowering the requirement.

Optimal Temperature and PH changes for each different enzyme
Pepsin works in the stomach, which is more Acidic
Lipase works in a more Basic environment

Temperature Changes:
An increase in temperature can result in denaturation.
HOWEVER
Decrease in temperature doesn’t, but it decreases the frequency of enzyme-substrate collisions and therefore reactions.

Speed Limit/Reaction Limit: Enzymes do cannot work more at a point
Ex.
If you put more and more substrate, the enzyme can only work so fast.
