Proteins have a three-dimensional structure that gives them a specific shape and allows them to perform many different functions in living organisms.

Question

Which one of these is not a function of proteins that depends on their structure?

a
transporting proteins across the plasma membrane of the cell
b
storing energy inside the cell
c
providing support internally and externally for cellular organelles
d
translating and receiving chemical signals

Answer 1

The correct answer is b) storing energy inside the cell.

While proteins can play a role in energy metabolism and some proteins may be involved in energy-related processes, the primary function of energy storage in cells is typically associated with carbohydrates (like glycogen) and lipids (like triglycerides), rather than proteins. The other options (a, c, and d) directly relate to specific functions of proteins that depend on their three-dimensional structure.
