Body Metabolism

Sports scientists distinguish between aerobic fitness (as achieved, for example, by long distance running) and anaerobic fitness (as achieved by sprinting exercise). ----------------------------------------------------------------------------------------------- Why have they chosen these particular terms to describe these two aspects of physical fitness? What are the various energy systems used by the human body and their role related to lactic acid during heavy exercise?

I am correct in assuming that a transection of the spinal cord at T6 would result in the patient being a paraplegic and therefore if the tendon under the knee were tapped the patient would not respond by kicking their leg?

diagram amino acid adsorption in the small intestinal lumen.

i need help diagraming the process of the following instructions. please help me. On a single page, diagram removal of an amino acid from protein by a peptidase in the intestinal lumen, followed by absorption of the amino acid. This process will include an epithelial cell actively transporting the an amino acid from the lumen of the intestine (brush border surface) to the inside of the cell, and then letting the amino leave the basolateral side of the cell by facilitated transport. The following things need to be shown and labeled somewhere in your diagram: 1. apical side of epithelial cell 2. lumen of intestine 3. peptidase enzyme 4. protein... click for more
