Enzymes Flashcards
1
Q
Define enzymes
A
Proteins that function as biological catalyst
2
Q
Explain the effect of changes in temperature on enzyme activity
A
Increase in temp- greater energy kinetic energy- greater collisions between enzymes and substrate molecules
3
Q
Explain the effect of pH on enzyme activity
A
pH: bond hold enzyme molecules in shape is broken down by changes in pH.
Shape of active site has changed- substrate molecules no longer fit. pH enzymes are denatured
