Question
_______ is responsible for selective uptake of material through cell membrane.
- Proteins
- Vitamins
- Water
- Riboflavin
Hint:
The selective uptake of materials is known as the selectively-permeable nature of the membrane.
The correct answer is: Proteins
- Proteins are responsible for the selective uptake of material through the plasma membrane.
- The plasma membrane or cell membrane is a layer that protects the cytoplasm of the cell from the external environment. An important quality is known for the cell membrane and that is its semi-permeable nature.
- Semi-permeability is responsible for the selective uptake of certain molecules into the cell across the cell membrane. This doesn't allow other molecules to pass through it. The compounds that can cross the membrane are usually small ions, micro molecules, proteins, etc.
The plasma membrane consists of lipids, protein and carbohydrates.
