Enzymes Enzymes: Q.1: What are Enzymes?Ans: Enzymes are biological catalyst that are made up of proteins they help speed up or alter a chemical reaction. but remain chemically unchanged at the end of a reactionQ.2: What is Ac...

Enzymes Activation Barrier Molecules that could react with one another often don't and this is due to a lacking of the necessary energy and so before a chemical reaction can occur, the activation energy barrier mu...

factors affecting enzyme activity temperature the rise in temperature makes the enzyme molecules vibrate more the increase in kinetic energy means more collisions occur with a higher energy, which means more reactions are likely to happen if the vibra...

cofactors and coenzymes co factors and co enzymes are essential for enzyme function some enzymes will only work if there is another no-protein substance bound to them. these non-protein substances are called co factors. some co factors are i...

Effects of temperature and pH on enzymes. High temperature denatures enzymes. Enzymes are damaged by high temperatues. For most human enzymes, this begins to happen from about 40 'degrees celsius' upwards. As the temperature increases beyond this, the enzyme ...
