Unformatted text preview: -temp. sensitive tyrosinase is not normal @ body temp.-temp. can deactivate the enzyme.-Himalayan rabbit also has temp sensitive tyrosinase PH: pepsin active @ low ph-trypin needs higher ph-higher salt [ ] less active enzymes. Salt interfers and denatures enzyme 3. controls on enzymes-feedback mechanisms-allosteric sites. (enzymes help reactions happen quickly) 4. bioluminescence 1. luciferase: works on luciferin (pigment) 2. luciferin (pigment) reacts with O2 and releases extra energy as light 3. bioluminescence in fireflies used to lure mates-squids lure food (preys)-fungi to lure animals to transmit spores-deopia (sea jelly) to lure prey...
