The answer is intercalated discs. They allow the heart muscle cells to function as one organ due to a phenomenon known as syncytium. This is where uninuclear cells fuse to form an apparent multinucleate cell. This way the heart muscle cells can contract in synch. Intercalated discs appear in the sarcomere's (of the muscle fibres) Z line.
ANSWER: A living organism intakes food, it breaks down into mostly water and large organic molecules. These large organic molecules are Fat, Proteins, Glucose, Starch and Cellulose. These molecules are still not usable by the cells so the body breaks these large polymers into small monomers.
In cow's muscles, protein muscles are built by tapping 4 amino acid monomers. Fat muscles are built by tapping 3 fatty acid monomers and 1 glycerol molecule.
Cows use glucose molecules to mix with oxygen to release chemical energy in cellular respiration. Cows can make fat molecules and glucose molecules because fatty acids and glycerols are made up of same atoms, C, H and O.
