BIOL 206 Lecture Notes - Lecture 15: Motility, Insulin, Cell Membrane
Document Summary
Sarcomeres are repeated throughout the length of the muscle cell: no intercellular junctions in skeletal muscle junctions, collagen fibers Are (cid:373)ade of protei(cid:374)s (cid:894)25% of body"s protei(cid:374)s(cid:895) Are found in the matrix of many connective tissues. Enzymes and diffusion: factors that affect animal metabolic rate. Time of day body temp peaks at 4pm for humans. Stress: way of measuring metabolic weight- ml o2/gram/hour, larger size= smaller metabolic weight. Larger= keep burning fuel to keep constant temperature. Ex: elephant is 200,000 times larger than a mouse but has a mass specific ratio with metabolic weight 1/12 as small. Bmr standardized per body weight: animal digestive functions are interdependent and precisely regulated. Ex: saliva is basic: ph of stomach = approaches 2, cell membrane short polypeptides last ones to digest, absorption is active transport, how move lipids in watery environments- lipo proteins.
