Which of the following is not a function of proteins:
1: regulating cell processes
2: building blocks of tissue for living things
3: serve as energy carrier molecules for cells
4: transporting substances in/out of cells
Answer: 3: serve as energy carrier molecules for cells
Proteins are macromolecules which are responsible in the regulation of cellular function. They basically play a role in ensuring that all cell processes are properly maintained, act as the building blocks for tissues, and aid in the transportation of substances between cells and their surroundings. Nevertheless, proteins are not the energy-carrier molecules of consumers. It is fulfilled by molecules such as adenosine triphosphate (ATP) which act to store and transfer energy for cellular processes. ATP, which is the universal mobile energy carriers, is formed from carbohydrates and fats that are broken down and not proteins
