Adenosine triphosphate is the energy source for work in the cell. It provides energy to the cell and ? A. deactivates compounds for some reactions by transferring a phosphate group.

B. transfers its adenosine group to DNA.

C. activates compounds for some reactions by transferring a phosphate group.

D. activates enzymes by transferring phosphate groups to change the shape of the enzyme.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
