Both mitochondria and chloroplasts have inner membranes with much greater surface area than their outer membranes. Discuss the contribution of the extensive inner membranes to the roles of these organelles
What will be an ideal response?
Both organelles use metabolic processes embedded in lipid membranes to produce cellular energy. The cristae of mitochondria produce ATP. The thylakoids of chloroplasts are the site of light energy capture and conversion to cellular energy. The extensive surface area of the folded inner membranes allows both organelles to produce much more energy than would otherwise be possible.
