ATPase muscle enzyme Featured 5 Dec 2002 Print

ATPase muscle enzyme

Calcium pumping ATPase enzyme. Computer model of an electrostatic potential surface map of part of the ATPase enzyme that pumps calcium in and out of muscle cells and controls muscle contractions. The name ATPase refers to this enzyme's ability to break up the ATP (adenosine triphosphate) molecule and release energy. This ATPase uses the energy to pump calcium ions in and out of muscle cells, and it is found in muscle cell membranes. Calcium ions are central to the process of muscle contraction. Enzymes are catalysts and so promote reactions and are not used up. They are also proteins. Proteins are long chains of amino acids. This protein has around 1000 amino acids and about 15, 000 atoms

Coloured X-ray of a spinal column nerve stimulator

Spinal column nerve stimulator. Coloured X-rayof the wires (green) of a spinal nerve stimulator.The spine (yellow) runs from top to bottom, withthe pelvis at lower frame. The wires lead to thestimulator (not seen), implanted under the skinnear the lowest rib. This male paraplegic isparalysed from the waist down. The wires enter thespinal canal through a hole cut between the 4th(L4) and 5th (L5) lumbar vertebrae (L5, the firstvertebra above the pelvis, is below L4). The wiresattach to the nerve roots of the sacral vertebraeS2-4 in L5. Using an external radio transmitter, bladder, bowel and erection control is restored
