Which of the following is an adaptation to increase the surface area of a part of a cell that is involved in cellular respiration?
A)the cristae of a mitochondrion
B)the outer membrane of a chloroplast
C)the grana of a chloroplast
D)the endoplasmic reticulum

Question

Quizplus · Accepted Answer

The cristae of a mitochondrion are folds in the inner membrane that increase its surface area, allowing for more space for the electron transport chain and ATP synthase to carry out cellular respiration. The outer membrane of a chloroplast and the grana of a chloroplast are adaptations for photosynthesis, not cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism, not directly involved in cellular respiration.
