Chapter 17.8, Problem 28LO

Summary Introduction

To explain: The role of calcitonin in regulating the blood calcium.

Concept introduction: The thyroid gland is a butterfly-shaped endocrine gland and is enclosed within a connective tissue capsule. The thyroid gland is located near the neck. It contains two lobes, which are connected by an isthmus. The thyroid gland primarily consists of thyroid follicles. Each follicular wall is formed by simple cuboidal epithelial cells (follicular cells). The lumen of each thyroid follicle is filled with a protein-rich fluid called colloid.

Biology Question

✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
