Document Summary
If the muscle fiber is stimulated repeatedly at a rapid rate = fused tetanus (max amount of tension and stays that way) Maximally extended: longest, most stretched out, very little overlap. Intermediate overlap: where maximum amount of force is generated (can still get shorter, enough overlap to generate force) Muscle fibers have a lot of mitochondria to make the atp. At maximal shortness, it can"t get any shorter. Creatine phopshpate: formed in liver, travels in the blood formed when muscles. Prodcut: lactic acid builds up in the muscle cells. Won"t run out of glucose have to maintain glucose in homeostasis. Can also make atp from fatty acids (stored in fat triglycerides) and can make atp. Atp is stored in fairly low concentrations within the muscle cells. When you start the contraction, the first bit of atp that is used just comes from the.
