Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles.
I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.
After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.
Hopefully this what you meant when you asked the question. Have a nice day/evening
