The resting membrane potential in muscle is about -90 mV. The reason for muscle cells having more polarized potential than neurons. Introduction: An actional potential is produced when a threshold potential is reached. The resting membrane potential is the membrane potential when the cell is at rest. The RMP is -70mV. At this moment, there are potassium ions in large concentration inside the cell, while sodium ions outside the cell. The actual membrane potential of a neuron tracks the equilibrium potential of potassium.

Summary Introduction

To determine:

The resting membrane potential in muscle is about -90 mV. The reason for muscle cells having more polarized potential than neurons.

Introduction:

An actional potential is produced when a threshold potential is reached. The resting membrane potential is the membrane potential when the cell is at rest. The RMP is -70mV. At this moment, there are potassium ions in large concentration inside the cell, while sodium ions outside the cell. The actual membrane potential of a neuron tracks the equilibrium potential of potassium.

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.
