Questions: Question 22 1 pts This is essential to the function of a protein. Peptide Bond Shape Side Chain

The answer is the second one: Shape.

Explanation:

• Peptide Bond: While peptide bonds are crucial for linking amino acids together to form a protein, they are not the aspect that is essential to the protein's function. They are more about the structure of the protein chain.
• Shape: The shape of a protein, also known as its conformation, is essential to its function. Proteins must fold into specific three-dimensional shapes to perform their biological functions effectively. The shape determines how a protein interacts with other molecules.
• Side Chain: Side chains, or R groups, of amino acids contribute to the protein's properties and interactions, but they are not the sole determinant of the protein's function. They influence the shape and reactivity but are not the primary factor.

In summary, the shape of a protein is critical to its function, as it determines how the protein can interact with other molecules and perform its biological roles.
