Diploid cells contain 2 sets of the same DNA where as haploid contains one set.....so our normal cells in our body (somatic cells) are diploid however our sex cells(gametic cells) which are the egg of a woman and sperm from a guy are only haploid which means they have only 1 copy of DNA......this is because they fuse with one another and add their DNA together to make a diploid cell

Electron transport trains create a concentration gradient of hydrogen ions outside the mitochondria and fewer inside the mitochondria and creates energy(ATP) by diffusing the hydrogen ions back in
