factors affecting enzyme activity Flashcards
1
Q
- substrate concentration
enzyme activity increases as substrate concentration ________
A
increases
2
Q
- substrate concentration
why does enzyme increase as substrate concentration increase
A
b/c there are more collisions between substrate and enzyme
3
Q
- substrate concentration
max rate is achieved when all
A
active sites of an enzyme are filled continuously with substrate
4
Q
- substrate concentration
rate becomes limited by how quickly
A
active sites become available
5
Q
- enzyme concentration
cell regulated metabolism by regulating which
A
enzymes are produced and active in the cell
6
Q
- Temperature
activity _____ increases temp ______
A
increases
increases
7
Q
- temperature
due to increased
A
enzyme-substrate collisions
8
Q
- temperature
high heat can
A
denature an enzyme by breaking down the tertiary structure
9
Q
- pH
each enzyme functions at an
A
optimal pH
10
Q
- pH
strongly acidic or strongly basic pH can
A
also cause denaturation of the tertiary structure
