| Text | RP1 - effect of temperature on an enzyme controlled reaction1. write an X on the glass halfway down 3 test tubes2. add 10cm3 of {{c1::milk solution}} to each tube3. add 2cm3 of {{c1::trypsin solution}} to 2cm3 of {{c1::pH 7 buffer}} in 3 more test tubes4. add all 6 test tubes to a water bath at temperatures from {{c1::20°c - 60°c}} and leave for 10 mins5. add the {{c1::trypsin and buffer solution}} to the {{c1::milk solution}} for each tube and mix 6. add tube back to water bath and time how long it takes for the X to be seen7. repeat for each temperature |
| Back Extra | - spec point: Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction.- questions often ask to use a tangent to find initial rate of reaction |

| Back | - multiple action potentials arrive in quick succession from same presynaptic neuron- all release neurotransmitter = threshold reached = AP triggered in postsynaptic neuron |
