What happens to certain nutrient molecules after they pass into muscle cells

These molecules are converted into smaller molecules which becomes polymers and other monomers. When they reach to the muscle cell, it is very definite that these nutrients and biomolecules will be metabolized by each organelle assigned with each specific task into helpful molecules that be the source of energy, repair, framework and other cellular activities.

These nutrients are mainly used for energy in the muscle cells especially during contraction and relaxation, producing movement for the host to be able to act or voluntarily be in motion.
