BIOB34H3 Lecture Notes - Lecture 3: Electrochemical Gradient, Thyroid, Munia
Document Summary
Relevance of basal (standard metabolic rate: there is a significant positive correlation. Pumping the proton to establish a proton gradient: gluconeogenesis. Building glucose from non-carbohydrate sources: myosin atpase. Membrane pacemaker hypothesis the rate of an animal ---------- is largely determined by its ------ Measure of how unsaturated the fatty acid in a mitochondrion. Unsaturation index = the easier for ions to leak = bmr because they expend more energy to re-establish the proton gradient. Factors: thyroid hormones (vertebrates) all vertebrates have a thyroid gland produces t3 (more potent) and t4 hormones there is a relationship between level of thyroid hormone (t3) and bmr, t3 levels = bmr. Spotted munia: measured under different treatment conditions, absence of thyroid causes bmr to go down, thyroid hormones affect bmr, body mass. Independence if you change one, the other does not change. Isometric scaling as one increases, so does the other: iso the same (the relationship is the same) slope =1.
