What happens to the P on ATP when it leaves the ATP molecule?

ATP is the energy currency molecule which is required for cellular processes.

Explanation:

When the cell require metabolic energy to perform a particular a task. From the ATP or adenosine triphosphate molecule one of three phosphate molecule gets displaced and liberates the resulting molecule becomes adenosine diphosphate or ADP. The phosphate molecule is used by the cell to perform different cellular and metabolic functions as a source of metabolic energy. The phosphate is released by the hydrolysis of the phosphoanhydride bond with the other phosphate group.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
