The hydrolysis of the phosphoester bond of ATP releases a large amount of free energy. True or false?

The following molecules act as either inhibitors or activators of the enzyme that converts fructose-6-phosphate to fructose-1,6- diphosphate. Which do you think are activators? (A) ADP B AMP ATP citrate

Draw the products that would be produced from phospholipase C cleavage of a glycerophospholipid with a phosphoserine head group, an alpha linoleic acid attached to C2 of glycerol and a linoleic acid attached to C, of glycerol. Draw these products at pH=1. Be sure to number the fatty acid carbons in your products.
