Warm up (Engage). -Make a “T” chart and write “Break” on left side And “Build/assemble” on the right side. Using the pictures below identify which one breaks things and which ones build or assemble. Chain Saw. Tape. Glue. Scissors. Stapler. Knife.

Enzymes, who are you?
Hydrogen peroxide (H2O2)
Liver= host many enzymes such as Catalase
Catalase turns H2O2 into…
H2O2 + Catalase (in liver) = H20 +O2
What is H20?
What is 02?
So where is bubbling coming from?
What’s the difference?
Enzymes are proteins that have an active site some where on the molecule where others molecules can land and react. Like a Pretzel
2.Cofactors and Coenzymes
1. Extreme Temperature are the most dangerous
- high tempsmay denature (unfold) the enzyme.
2.pH (most like 6 - 8 pH near neutral)
3.Ionic concentration (salt ions)
Inorganic substances (zinc, iron)andvitamins (respectively) are sometimes need for proper enzymatic activity.
Iron must be present in the quaternary structure-hemoglobin in order for it to pick up oxygen.
a. Competitive inhibitors: are chemicals that resemble an enzyme’s normal substrate and compete with it for the active site.
Inhibitors that do not enter the active site, but bind to another part of the enzyme causing the enzyme to change its shape, which in turn alters the active site.
