Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

Insulation and long-term energy storage
The function of FATS is insulation and long-term energy storage. Excess glucose in the body is converted to fats and then stored in certain location like liver, around the heart, and under the skin. The fats are converted back to glucose during starvation. Fats are deposited under the skin to provide insulation against heat loss.
Explanation:
Proteins are the mains structural molecules in the body. They are coded for by the DNA in cells that instruct how these proteins should be manufactured. Proteins make up the muscle tissues, most enzymes, antibodies, hormones, hair, nails, and etcetera. Protein is broken down for energy as a last resort during total starvation (when fat deposits have been exhausted) and when this happens it leads to body wastage. Glucose is the main energy source of cells.
