Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Sense organs are involved in the transmission of data (through neurons) to the specific place inside the nervous system. Such sense organs may range from simple microscopic structures, like dendrites, to complex structures, like ear and eye. Receptors can be classified into three categories based on the stimulus origin, modality, and its location in the body. The classification of taste receptors: (i) based on the modality of the stimulus: chemoreceptors; (ii) based on the stimulus origin: exteroceptors; and (iii) based on the location of receptors in the body: specific senses.

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.

Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
