WebbCambridge International AS and A Level Biology builds on the skills acquired at Cambridge IGCSE (or equivalent) level. The syllabus includes the main theoretical concepts which are fundamental to the subject, some current applications of biology, and a strong emphasis on advanced practical skills. WebbSome enzymes contain a non-protein component called a prosthetic group. The prosthetic group is similar to coenzymes in function, but they are more tightly bound to the enzyme. Heme-iron is a prosthetic group e.g. in catalase and functions as the electron acceptor.
