$100 Jeopardy Menu Enzymes are what type of macromolecule? Protein
the rate of a reaction
Jeopardy Menu Increase / speed up
This diagram shows what special property of enzymes?
Jeopardy Menu That enzymes LOWER THE ACTIVATION ENERGY
Enzymes bind to these. They are also known as reactants in a chemical reaction.
Jeopardy Menu Substrates
What physically happens to an
enzyme when it is “denatured”
Jeopardy Menu It is literally bent out of shape. They lose their original shape
Your hand is bitten by a spider that injects an enzyme that causes cell death. How can you best stop or slow down cell death?
Jeopardy Menu Change the environment (pH, temperature, ionic conditions) that surround the enzyme
The lock-and-key model of enzymes shows that enzymes only fit with. . .
Jeopardy Menu A specific substrate (enzymes are substrate- specific!)
In the following reaction, what are the products?
H 2 O 2 ----> O 2 + H 2 O
Jeopardy Menu O 2 + H 2 O catalase
Amylase is an enzyme that works in the mouth where the pH is around 7. When saliva is swallowed and travels to the stomach where the pH is acidic around 2, what will happen to the enzymatic activity of amylase?
Jeopardy Menu It will decrease!
What are the three environmental factors that affect the activity of the enzyme?
Jeopardy Menu Temperature, pH, and ionic conditions
Enzymes usually work better at warmer temperatures, but when they get too hot, what happens to them?
Jeopardy Menu They get denatured
What happens to enzymes after they help catalyze the reaction?
