Kate explains to Lisa the reason proteins have a globular shape in water.
Which of the following is correct?
O Proteins are made of nucleic acids that don't like water.
Some amino acids in a protein are hydrophilic and form a core to "hide" from
water.
Some amino acids in a protein are hydrophobic and form a core to "hide" from
water.
Proteins can have any random shape and still be able to do their job in the cell.
Water breaks down proteins.

Expert Solution
Step 1

Protein molecules have a hydrophobic component and a hydrophillic component. The hydrophillic component interacts with water molecules and develops intermolecular forces which give the characteristic globular shape to proteins in water. The core is made up of hydrophobic core since it repels water. Hence option (C) is correct.
