Consider the hypothetical serine protease, which shows the specificity pockets. The S 1 S1 pocket has a glutamic acid in the bottom, the S 2 S2 pocket is small and hydrophobic, and the S 1 ' S1' pocket is deep and hydrophobic. Suggest an amino acid sequence that this protease would cleave.

Suppose a lab group reports a ppercent yield of sand of 105. is it really possible to collect more sand than was originally represented? what is the possible explanation for the extra product?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.
