Ketogenic diets are rich in fats and oils and carbohydrate intake is drastically reduced. You know that during cellular respiration, cells break down glucose and release electrons that flow to oxygen in the mitochondrion producing large quantities of ATP. Yet people following a ketogenic diet can produce sufficient quantities of ATP. Explain why a fat molecule actually produces more ATP than a glucose molecule.

ya the other dude is right

you have the answer? i really need it

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
