Chemguide: Support for CIE A level Chemistry
Learning outcome 8.3(d)
This statement is a brief introduction to enzymes as catalysts.
Before you go on, you should find and read the statement in your copy of the syllabus.
Unless you have already come across enzymes in biology or biochemistry, don't get too bogged down in this at this stage. In fact, unless you have already done the chemistry of amino acids and proteins, it is hard to explain much about enzymes apart from in very general terms.
Essentially, all you need to know for now is that:
You will find this (and a lot more) on the page about proteins as enzymes.
You should only read down as far as the paragraph under the first diagram in the Active Sites section. You don't need to go beyond that. And don't waste time looking at the page about the structure of proteins. You will come back to proteins in the second half of the course in Section 21.
