The experiments described in Figures 1 and 2, which demonstrate the chemiosmotic mechanism. Given: Figure 1: An experiment to demonstrate chemiosmosis. Figure 2A and B: The formation of adenosine triphosphate (ATP); (A) The structure of ATP synthase and (B) Demonstration that ATP synthase has a rotary motor. Introduction: Chemiosmosis is the second stage of the oxidative phosphorylation after the electron transport chain (ETC). As a result of the transport of electrons across the respiratory chain in ETC, a proton concentration gradient takes place to the intermembrane space from the mitochondrial matrix. In chemiosmosis, the production of adenosine triphosphate (ATP) occurs by the influx of the protons back into the matrix of the mitochondria.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.
