2. occurs in the human body..

3. Enzymes are shape specific to a substrate.

4. Base your answers to questions 9 & 10 on the diagram below, which represents stages in the digestion of a starch. 9.
10.
High temperatures can destroy biological catalysts (enzymes will denature).

5. Base your answers to question 11 on the information below:
An enzyme & soluble starch were added to a test tube of water & kept at room temperature for 24 hours. Then, 10 drops of glucose indicator solution were added to the test tube, & the test tube was heated in a hot water bath for 2 minutes.

6. *pepsin- stop function or slow down.
*pH in small intestine is between , but pepsin functions normally between
*400C fever = slow/stops enzyme function (works best at 370C)
*Ptyalin & Trypsin both cant digest the same type of food because enzymes are specific based on shape.
