"I researched how cells die when acid comes in contact with the cell membrane. I found that acid lowers the pH of the cytosol. Cytosol is the liquid of the cytoplasm, and the organelles make up the rest of the cytoplasm. So, cytoplasm is like Jell-O salad, where the organelles are like pieces of fruit, and the cytosol is the Jell-O itself. The acid causes the proteins in the cell membrane to open up, or "unfold," which means they fall out of their usual coiled shape – like a spring that is losing its shape. This process is called denaturation."
