This is because iron is used to make a protein called hemoglobin. This protein helps blood cells carry oxygen around the body.

Answer:
Due to less steps and requires less energy.
Explanation:
The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.
