Question
How does Singer and Nicholson's model of cell membrane varies from Robertson's model?
- It differs in the arrangement of the number of lipid layers.
- It differs in the arrangement of lipids.
- It differs in the absence of protein molecules in Nicholson’s model.
It differs in the arrangement of proteins.
It differs in the arrangement of proteins.
Hint:
The plasma membrane model of Singer and Nicholson varies from that of Robertson in the arrangement of proteins.
The correct answer is: It differs in the arrangement of proteins.
- Singer and Nicholson's model varies from Robertson's model in the arrangement of proteins.
- Robertson's model explains that lipids layers are present in between two protein layers.
- Singer and Nicholson's model explains that the proteins are embedded in the lipid bilayer.
