Glycerol is an extremely viscus solution, density of 1.26 g/cm3, that is usually measured by weight. How many grams of glycerol are requires for a reaction the calls for 3.27 mL of glycerol.

List four observations that indicate that a chemical reaction may be taking place

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?
