A
Enzyme + substrate
Enzyme substrate complex (combined)
Enzyme + products
Substrate= molecule on which enzyme acts
Active site= part of enzyme which combines with substrate
2
Q
Factors affecting enzymes
A
Anything outside small optimum range
- temperature- causes enzymes become denatured, to expand and change shape
- pH levels
- concentration
- Co-factors and co-enzymes which catalyse reaction
3
Q
Enzyme description
A
Lock and key
Proteins which do not change shape but allow chemical reactions to take place in normal environment
