DOES THE AMOUNT OF SUBSTRATE USED AFFECT ENZYME RATE? QUE STIO N F LYNN LLARSA NIA
Transcript of Bio lab
- 1. WHAT ARE ENZYMES AND SUBSTRATE?Enzymes are catalysts for chemical reactions in living things.Substrates are specific reactants that an enzyme acts on.
- 2. LAB PROCEDURESteps for Lab1. Set up test-tubes2. Put different amounts of H202 and water3. Record the reaction -Enzymes Source: Catylase in potato -Substrate Source: H2O2 -Independent Variable: Amounts of H2O2 -Control: Potato
