1.7 enzyme action Flashcards
1
Q
what does enzymes do?
A
speeds up rate of reaction without being changed by the reaction
1
Q
definition of enzymes
A
biological catalysts that speeds up & control chemical reactions in the body without being changed by the reaction
2
Q
what is activation energy?
A
minimum energy required before a reaction
3
Q
how is an enzyme-substrate formed?
A
substrate binds to the active site of an enzyme due to the temporary bonding
4
Q
what is the lock & key theory?
A
enzyme will only bind to 1 substrate due to specific shape of active site
5
Q
what is the induced-fit theory?
A
active site forms its shape as it interacts with substrate, which strains particular bonds on the substrate
therefor it lowers Ea & break bonds to form products
