Question

Part A 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 1, 2, and 4 are correct. Only statements 2, 3, and 4 are correct All of the listed statements are correct. Submit Request Answer

Explanation / Answer

1. All of them are true

1) The protein folds to make itself as compact as possible.... yes
2) The packing of the protein is such that hydrophilic residues appear on the surface where they can interact with an aqueous environment.... yes
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 , reactions occurs on these sites
4) Regions of secondary structures folding on one another are examples of the protein's tertiary structure... yes

2.
