Co-factors are non protein substances that activate enzymes. Most enzymes cannot work without co-factors.
Some co-factors are metallic ions while others are vitamins. They are required in small amounts and can be reused.
Co-enzymes are organic non protein substances that work in association with particular enzymes. Many co-enzymes are derived from vitamins.
