What type of macromolecule is an enzyme?
protein
What does an enzyme act as in the body?
Catalyst
What does a catalyst do?
Speed ups chemical reactions
What is a special characteristic of enzymes?
They’re reusable
What is the term that means they can only fit one substrate?
substrate specific
Are all catalysts enzymes?
no
Are all enzymes catalysts?
yes
What is the ending of an enzyme to it’s substrate?
-ase, -ose
What are the two things an enzyme does?
digestion and synthesis
How do enzymes work?
they weaken the chemical bond of the substrate and lowers the activation energy needed to do the chemical reaction
Synonyms of substrate
reactant and input
Synonyms of products
output and result
What is the enzyme-substrate complex the same as?
the lock and key example
Lock:Key is the same as….
Enzyme:Substrate
What is the induced fit model?
A change in the active site to fit the substrate
What are the factors of what affects an enzyme?
environmental (pH and temp)
cofactors and coenzymes
enzyme inhibitors
concentration of substrate
What does heating up an enzyme for to it?
denatures the enzyme
What does pH stand for?
potential of hydrogen
What is the range of the pH scale?
0-14
What is considered acidic?
0-6
What is considered basic?
8-14
What are sometimes needed for proper enymatic activity?
inorganic substances (zinc and iron)
Example of a cofactor
iron to help with hemoglobin
Two types of enzyme inhibitors
competitive and noncompetitive
