    Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

    is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains a watersoluble red pigment‚ betacyanin
