In living cells, atp stores the energy that a. spontaneous reactions release b. spontaneous reactions absorb c. cells radiate as heat d. cells absorb from sunlight

ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released (for example  glycolysis, the citric acid cycle or oxidative phosphorylation and beta-oxidation). 

ATP is made of three components: the triphosphate, the sugar ribose and a nitrogenous base (adenine).

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
