<span>The correct answer is that a completely different protein will be synthesized. Proteins are made out of long chains of amino acids. There's 500+ of them but only 20 or so are used for humans. They have infinite amounts of combinations and each combination synthesizes a different protein. Our body knows what it needs so it synthesizes it from food that we take.</span>

When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume.
Hope this helped :)
