Answer: The functions of ferritin and glycogen is to store the needed molecules for the organism.
Explanation:
Ferritin is an intracellular protein that stores iron, and it releases this iron when the body needs it. So, ferritin is found mostly inside cells, with very little actually circulating in blood. The greatest concentrations of ferritin are in the cells of the liver and in the cells that are part of the immune system.
Ferritin is stored until it’s until it's necessary to make more new red blood cells. The body will signal the cells to release ferritin and it binds to transferrin, another protein that controls levels of iron.
If a person doesn’t have enough ferritin within its cells, iron stores can deplete. So it is important to have normal levels of ferritin.
On the other hand, glycogen is a multibranched polysaccharide of glucose that serves as the main form of energy storage. This molecule is made and stored in liver and muscle cells. When energy is needed, glycogen is broken down into glucose. Glucose is the most important molecule that cells use as an energy source.
So, the functions of ferritin and glycogen is to store the needed molecules for the organism.
