Question

Quizplus · Accepted Answer

The plasma membrane accounts for only a small percentage of the total cell membrane area, while the endoplasmic reticulum (ER) membranes (including those of the smooth and rough ER) comprise about half the total membrane area. In cells such as hepatocytes, which are rich with mitochondria, the inner mitochondrial membrane also has a notable surface area, due to its extensive invaginations called cristae. Please refer to Table 12-2.
