Answer:
C
Water moves out or in to balance cell concentration
Answer:
Phospholipids derived from glycerol are called phosphoglycerides.
Lipid-soluble molecules can readily pass through a lipid bilayer. Surprisingly, some small polar molecules are capable of permeating the lipid bilayer without the aid of a membrane transport protein. Examples include water (H2O), glycerol (C3H5(OH)3), urea (CH4N2O), and ethanol (C2H6O).
Phospholipids are amphiphilic lipids consisting of a glycerol backbone or an amino-alcohol sphingosine backbone, which is esterified to one or two fatty acids, a phosphate group, and a hydrophilic residue.

ATP usually releases energy by breaking down the weak phosphate cell present. The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.
