Unformatted text preview: QUIZ: why can certain enzymes break down starch (glucose polymer), but not cellulose (glucose polymer)? a. Enzymes speed up rxns b. Enzymes arent consumed c. Enzymes are very specific d. Enzymes are regulated Enzyme Reaction 1. Regulate synthesis 2. Make them inactive; activate when needed: a. Feedback inhibition b. Allosteric regulation c. Competitive inhibition Enzyme Regulation: Feedback inhibition Slowing down production of pathway Coming back to earlier point Enzyme Regulation: Allosteric Regulation Allosteric- changing the shape Regulation Shape of active site changed When turned off negative allosteric regulation Turn on- positive allosteric regulation Changing shape Can occur naturally in cell Competitive Inhibition: No second site; something comes in and blocks active site Competitive inhibitor occupies active site...
