Answer:
Rough endoplasmic reticulum
Energy production depends on metabolic pathway and ATP yield, with fats having the highest ATP yield with ketone bodies,followed by Carbohydrates then proteins.
Energy produced by one glucose molecule yields final ATP of 5-7 through glycolysis and 17-25 through citric cycle.
Proteins energy prooduction is considered to be more healthy because unlike fats and carbohydrates they are not stored but used up immediately by the body.
I hope this is will help
