Question

What is one reason the membrane proteins could not go where the Davson-Danielli model thought they should go, sandwiching the lipid membrane on either side? A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment. B. Proteins are not normally found in cells. C. There was not enough protein to cover both sides of the membrane. D. They were correct, the proteins do go there.

Answer 1

Answer: A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment.

Explanation: ummm Founder Education

Answer 2

Membrane proteins are part of the biological membranes. Proteins are hydrophobic, and lacking in an aqueous environment was the drawback of the Davson-Danielli model. Thus, option A is correct.

What is Davson-Danielli model?

Davson-Danielli gave the membrane model, which was also called a lipoprotein sandwich model. It was proposed to show the selective nature of the membrane structure and resembles a sandwich due to its structural organization.

The lipids were layered in between the two protein layers on either side making it look like a sandwich, but the model was rejected as it didn't explain certain permeable molecules.

The arrangement was also contradictory as the proteins are hydrophobic and were placed on the outer side making them exposed to the water molecules. This constricted the movement, and the model failed.

Therefore, the hydrophobic nature of the protein failed the Davson-Danielli model.
