Question

Which of the following statements about globular proteins are true?

1) The protein folds to make itself as compact as possible.
2) The packing of the protein is such that hydrophilic residues appear on the surface where they can interact with an aqueous environment.
3) Irregularities of the protein's surface allow for the formation of clefts, which are often where the protein promotes a chemical transformation.
4) Regions of secondary structures folding on one another are examples of the protein's tertiary structure.

Only statements 1, 2, and 3 are correct. Only statements 2, 3, and 4 are correct. Only statements 1, 2, and 4 are correct. All of the listed statements are correct.

Explanation / Answer

I think all of them are correct.

1) The protein folds to make itself as compact as possible. --->Correct


2) The packing of the protein is such that hydrophilic residues appear on the surface where they can interact with an aqueous environment.--> This is true


3) Irregularities of the protein's surface allow for the formation of clefts, which are often where the protein promotes a chemical transformation. ---> Clefts are the active sites of protein where reaction occurs


4) Regions of secondary structures folding on one another are examples of the protein's tertiary structure.

---> Correct sincetertiary structures are formed by folsing of secondary
