Question

Differentiate between hormone and enzyme.

Answer 1

• Enzymes are synthesized within a cell to function there or are secreted to the exterior through active transport processes, whereas hormones are released directly into the blood stream and are distributed throughout the body where they exert their effects upon a number of different target tissues.
  
• Moreover, enzymes are generally highly specific, catalyzing a single type of reaction, whereas hormones have a range of effects.
  
• Hormones maintain their levels through negative feedback, whereas it is not so with enzymes.
