Enzymes as organic catalysts which increase the rate of biochemical reactions. All enzymes are proteins , but all proteins are not enzymes.
Hormones: A molecule , usually a peptide or steroid, that is produced in one part of an organism and triggers a specific cellular reaction in target tissues and organs some distance away.
Enzymes and Hormones
1. All enzymes are proteins
2. Mostly enzymes perform reactions at the place of origin i.e. in cells where they are produced.
3. Enzymes are not translocted from one part to another part of the cell or plant part.
4. Enzymes are biological catalysts. They catalyze the biological reactions
5. As enzymes are catalysts, at the end of reaction they remain unchanged and can be reutilized
1. The hormones may be polypeptides, terpenoids, steroids, phenolics compounds or amines.
2. Hormones perform activity at some distance away from the place of origin
3. Hormones are first synthesised in one part and then translocated to another part where they perform activity. Most of the hormones show polar translocation.
4. Hormones are not catalysts. They simply initiate biochemical reactions
5. As hormones are not catalysts, they participate in biological reactions and their chemical composition is changed.
