Question

Which of the following can combine in a cell to convert a lower-energy molecule into a higher-energy molecule? 1.) ADP + P + energy 2.)ATP + P + energy 3.)ADP + P 4.)ATP + P

Answer 1

I guess it's option 2

Answer 2

The answer is 2.)ATP + P + energy

ATP here is the Adenosine triphosphate, and it is composed of the base of nitrogenous adenine, and the five carbon sugar ribose along with three phosphate groups.

The Adenosine triphosphate is hydrolyzed into the ADP during the reaction formula for free energy. i.e., ATP+H2O→ADP+Pi
