Answer #1

ANSWER: False

Explanation- This is because the quaternary structure of protein needs a folding of 2 or more polypeptides known as the subunits, in a particular conformation. Whereas even a single polypeptide chain can act as a functional protein which does not have a quaternary structure.

A protein needs to acquire it's 3D form to be functional. This happens when the protein takes up a tertiary structure. Thus, all the proteins must reach their TERTIARY STRUCTURE before they are able to function.

Biochemistry: (True/False) Proteins need to be in a controlled environment that is similar to that which they came from. By lowering the temperature of the environment you can speed up the rate of all chemical reactions that are occurring in that mixture, therefore speeding up proteolysis and the rate of degradation.
