Enzymes are biological catalysts produced by living organisms.
Enzymes speed up the biological process that takes place inside living cells - without biochemical processes would happen to slowly and organisms wouldn’t survive.
Biochemical reactions:
Respiration
Photosynthesis
Protein synthesis
catalysed by enzymes
The rate of an enzyme varies on several conditions like temperature and pH.
The optimum conditions are the conditions that enable an enzyme to work at its highest activity - different enzymes require different conditions to work at their highest activity.
