Blood is mostly aqueous and will dissolve ionic compounds. Cholesterol is organic and does not dissolve in water. High density and low density lipo-proteins [LDL and HDL] are needed to carry the otherwise insoluble cholesterol within and throughout the Blood.

Carrier-assisted transport is a mechanism in which a carrier molecule assists in the movement of a substance across a biological membrane. The carrier molecule can bind to the substance and facilitate its transport across the membrane. This process is typically passive and does not require energy input from the cell.
ATP (adenosine triphosphate) is the organic molecule needed for active transport. It provides the energy required to pump molecules against their concentration gradient across a cell membrane.
The molecule produced by the mitochondria is the energy-carrier molecule. It's name is adenosine triphosphate, or ATP for short.
it is carring substances both into and out of the cells.
Because of facilitated diffusion(, which nutralizes it from a higher to a lower concentration.)
The carrier molecule involved in photosynthesis is (A) chlorophyll.

Flavin adenine dinucleotide (FAD) serves primarily as a hydrogen atom carrier molecule in cells.

A carrier molecule is a compound that can accept a pair of high energy electrons and transfer them along with most their energy to another molecule. Straight out of the 9th grade textbook
The carrier protein changes shape , shielding the molecule from the interior of the membrane.
