Question
Chapter 3, Problem 1CT
Summary Introduction
To review:
The mode of glandular secretion when the DNA (deoxyribonucleic acid), RNA (ribonucleic acid), and membrane components are present.
Introduction:
The different modes of glandular secretion include the eccrine (merocrine), apocrine, and holocrine secretion. In the merocrine secretion, the cell is not destroyed and remains intact. Rather, the secretory product is packaged into secretory vesicles and is released onto surface of the cell through exocytosis. For example, secretions from globlet cells in the intestine. During the apocrine secretions, only the apical portion of the cell’s cytoplasm is shed off to release secretory product. For example, secretions from lactiferous cells of the mammary glands.

a) Give the importance of the hexose monophosphate shunt.
b) Give the importance of its products?
c) In which type of tissue and which part of the cell does it commonly occur?
A sebaceous gland in our skin secretes oils to protect the skin. This is a holocrine gland. What is true about the sebaceous gland?
All of the answers are correct
O The sebaceous gland disintegrade when they release substances
The cells in the sebaceous gland release oil by decapitation of the cell
Sebaceous glands secrete substances via exocytosis
Secretory vesicles fuse with the cell membrane to release their
contents to the outside of the cell. In this process, the membrane
of the secretory vesicle becomes part of the cell membrane. Because
small pieces of membrane are continually added to the cell membrane,
we would expect the cell membrane to become larger and larger as
secretion continues. However, the cell membrane stays the same
size. Explain how this happens.
