Cell membrane also contains _ place by active and passive transport:
Correct answer: C. Charged Pores.
- A. Lipids
- B. Corner Proteins
- C. Charged Pores.
- D. Carbohydrates
Explanation
Charged pores, also known as ion channels, are essential components of the cell membrane that facilitate the exchange of materials and play a crucial role in active and passive transport. Option B, "Corner Proteins," is not a recognized component of the cell membrane, and it should have been "Carrier Proteins" instead. Lipids (option A) form the basic structural framework of the membrane, and processing of glycoproteins (option D) is related to post-translational modification but not primarily responsible for material exchange or transport. Thank you for pointing out the correction.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
