The Anhydride Formed Between a Carboxylic Acid and a Phosphate

question 19

Multiple Choice

The anhydride formed between a carboxylic acid and a phosphate (Figure 3-45A) is a high-energy intermediate for some reactions in which ATP is the energy source.Arsenate can also be incorporated into a similar high-energy intermediate in place of the phosphate (Figure 3-45B) .Figure 3-45C shows the reaction profiles for the hydrolysis of these two high-energy intermediates.What is the effect of substituting arsenate for phosphate in this reaction? (A)


(B)
