Chapter 28, Problem 28.16UKC

(a)

Interpretation Introduction

Interpretation:

It should be determined that where is LH produced, and to what class of hormones does it belong.

Concept introduction:

Hormones are chemical substances synthesized in small amounts by endocrine tissues and carried by blood stream to another tissue, where it acts as a messenger to regulate the function of the target tissue or organ.

There are three major classes of molecules which function as hormones in vertebrates and they are,

  • Amino acid derivatives: It is a derivative of an amino acid formed by the reaction at the side chain functional group, carboxylic acid group, and amino group or by the replacement of a hydrogen atom by heteroatom.
  • Polypeptides: Polypeptides are organic polymers having several amino acids attached to each other in a chain.
  • Steroid: Steroids are a type of organic compound having a molecular structure with four rings connected to each other.

Follicle stimulating hormone (FSH) and luteinizing hormone (LH) are the two hormones involved in fertility which are produced by the pituitary gland.

Explanation of Solution

LH (luteinizing hormone) is an important hormone involved in fertility which is produced by the pituitary gland. It is a polypeptide hormone.

Interpretation Introduction

Interpretation:

It should be determined that where is progesterone produced, and to what class of hormones does it belong.

Explanation of Solution

Progesterone is responsible for the physiological changes in women at specific phases of their life starting in puberty.  It is a steroid hormone produced in ovaries.

(c)

Interpretation Introduction

Interpretation:

It should be determined that whether the progesterone producing cells have LH receptor on their surface or does LH enters the cells to carry out its function.

Explanation of Solution

Progesterone producing cells have LH receptor. LH stimulates both estrogen and progesterone production.  Before ovulation LH release is stimulated by estrogen but after ovulation it is inhibited by both estrogen and progesterone.

(d)

Interpretation Introduction

Interpretation:

It should be explained that whether the progesterone bind to a cell-surface receptor or does it enter the cell to carry out its function.

Explanation of Solution

Progesterone is responsible for the physiological changes in women at specific phases of their life starting in puberty. It is a steroid hormone produced in ovaries. Steroid hormones are lipid soluble and so it can enter cells.
