A protein's native conformation is
A) its shape when it is first made.
B) its shape when it is not bound to a substrate.
C) its three-dimensional shape in which it is biologically active.
D) the shape of the protein without any cofactors.
E) the shape of the protein without any coenzymes.

Question

Quizplus · Accepted Answer

A protein's native conformation is its biologically active, three-dimensional shape. This shape is essential for the protein's proper function and may be disrupted by various factors, such as denaturation or mutations. Therefore, understanding the native conformation of proteins is crucial for studying their structure and function. Choices A, B, D, and E are not correct because they either refer to the protein's initial shape, its binding status, or the presence of cofactors or coenzymes, which are not necessarily related to the native conformation.
