Homework Help: Bio

Posted by Grade 12 Biology on Monday, February 25, 2008 at 8:40pm.

Hey! I am doing a biology lab in which we take liver and sand and place it in a test tube, to see it if it will react with hydrogen peroxide. One of the test tubes just has sand in it, and no reaction occurs. This is because the sand acts as a control and is inorganic meaning it won't react with the enzymes in the liver. My question, what exactly does it mean that the sand is a control? Thanks

This is my answer: the control means that it controls enzyme activity (but I am not sure)

Thanks !

Also, how does one tell if a catalyst is inorganic or organic
