The Cell Membrane. Have a nice day! :)
Answer:
Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber. The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions. The calcium ions diffuse into the muscle fiber.
Explanation:
There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Hope this somewhat helps!

Answer:
Rupture of the cell, releasing cytoplasmic contents.
Explanation:
Rupture of the cell to release the cell content into the intercellular space occurs in necrosis. This event does not occur in apoptosis. Release of the cell content into the intercellular space in necrosis results in stimulation of inflammatory response. Apoptosis does not include inflammatory reaction and hence, the cells do not rupture to release their content.
