|
enzymes
|
biological catalysts (usually proteins) that speed up the rates of chemical reactions that take place within the cells
|
|
|
without enzymes...
|
many of the reactions in your body would not happen quickly enough to keep you alive
|
|
|
catalase
|
type of enzyme which is present in most cells and found in very high concentrations in liver and blood cells
|
|
|
hydrogen peroxide
|
H2O2 chemical produced by certain chemical reactions in the body. very toxic and will kill the cells if it is not immediately broken down. (hydrogen peroxide is used as an antiseptic because it kills bacterial cells. it's not good for open wounds though, because catalase in the blood quickly breaks it down.)
|
|
|
Catalase promotes the decomposition of hydrogen peroxide in what chemical reaction?
|
2H2O2--------- 2h20 + O2
catalase |
|
|
when hydrogen peroxide is broken down. what is the result?
|
water and oxygen gas
|
|
|
in the lab how did we measure how quickly the reaction occurs?
|
by measuring the amount of oxygen gas being given off
