Question 11

• / 10 pts

(TCO 2) 4) 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. (10 points)

Your Answer:

Both the mitochondria and chloroplasts are to be considered as primitive organelles, they are able to sustain life, energy production, synthesis and transport of material and maintaining their structure. The mitochondrial membrane consists of small structures called Cristae. Cristae is the primary site for ATP synthesis and the maintenance of the proton gradient in the mitochondria. Due to the fact that cells do require a lot of energy, This study source was downloaded by 100000829346646 from CourseHero.com on 07-31-2021 07:48:10 GMT -05:00
