1.	Explain the terms(a) Co-factors(b) Prosthetic groups(c) Co-enzymes
Answer» Co-factors: Co-factors are non-protein constituents bound to the enzyme to make the enzyme catalytically active. Prosthetic groups: They are non-protein organic factors which are firmly attached to the apoenzyme. E.g. In peroxidase, haemoglobin, myoglobin and catalase, haem is prosthetic group. Co-enzymes: It is a non-protein organic compounds which is loosely attached to an apoenzyme. The essential component of many coenzymes is vitamins. E.g. NAD and NADP contain niacin.
