Fuel cells have become a favorable future power source because they can convert chemical energy directly into electricity in a highly efficient‚ environmentally friendly manner. Although fuel cells were invented one and a half centuries ago‚ only recently has it become feasible for them to compete with existing energy production systems. Among the various types of fuel cells‚ proton exchange membrane (PEM) fuel cells promise to become a viable power source for transportation as well as a distributed

directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further oxidized in the mitochondria. Each mitochondrion is enclosed by two membranes separated by an intermembrane space. The intermembrane space extends into the folds of the inner membrane called cristae which

Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell
