MCQ
What is the source of receptor proteins?
- AInterior of a cell
- BCell wall
- COut of cell wall
- ✓Fixed in the cell membrane partially inside and partially projected outward.
✓
Answer
Correct option: D.
Fixed in the cell membrane partially inside and partially projected outward.
The source of receptor proteins is fixed in the cell wall, partly inside and partly projected out of the cell wall.
This is so that chemical messengers can interact with the outside portion of receptor protein, which transfers the signal to interior of cell via the receptor protein.
Hence, signal is transferred from outside the cell to inside without the messenger having to cross the cell membrane.
