We define:
Chemical reaction: A process where atoms and bonds are re-arranged.
Consider the Benedict result from the four test tubes:(1. water, 2. starch, 3. saliva, 4. saliva + starch)1) Which one showed presence of sugar? Why not in the others?2) What was the purpose of dipping in warm water?3) What was the purpose of the boiling water in the end?
Digestion by saliva Amylase
Starch Glucose
Example1:
Substrate: Starch(Amylose)
Products: Glucose molecules
Process of Enzyme Action: Notes
Step 1: Enzyme binds substrateStep 2: Enzyme and Substrate form
a complex.Step 3: Changes occur in substrate.Step 4: Release of products,
enzyme can start again.
