In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
Answer:
Both store materials needed by the organism.
Explanation:
Proteins and carbohydrates are two biomolecules present in living organisms. They perform varying functions in the body of an organism. According to this question, a specific protein (ferritin) and carbohydrate (glycogen) is described.
Ferritin is a protein molecule containing Iron (Fe). Iron is needed by living organisms as it plays a vital role in organism's metabolism. On the other hand, glycogen is a carbohydrate molecule that is made up of glucose molecules, needed by living organisms.
Based on the description of the two biomolecules provided, they are similar in their primary functions for an organism in the sense that THEY BOTH STORE MATERIALS (glucose and iron) NEEDED BY AN ORGANISM.
