Lecture 9 Flashcards
What does the ending -ase usually mean?
it is an enzyme
Enzyme’s main way to make reactions happen faster
lower activation energy
Explain enzyme’s role in oxygen radicals in the body
oxygen radicals are extremely reactive and harmful
enzymes can break down these radicals fast
Define activation energy
energy you need to put in for a reaction to occur
Define transition state
highest synergy point
What happens during transition state?
going toward the product is equally likely as not going toward the product
What do enzymes break down the steps into?
reaction intermediates
What are enzymes composed of?
Subunits
How are enzymes effected by the reactions they are used in?
They are unchanged
What bonds do enzymes form with their substrates in their active sites?
non-covalent and sometimes transiently covalent
Why are the side chains of the active site close together?
Because of the tertiary structure
What happens when denaturation happens?
It takes away the tertiary structure
Define prosthetic group
extra cofactors that bind to enzymes to assist it
(like iron–not a part of the actual protein)
Enzymes are extremely…
Specific
Define competitive inhibition
The competition directly binds to the active site of the enzyme
