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.

- 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.arrow_forwardA 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 exocytosisarrow_forwardDefine each of these terms: a freely permeable membrane, an impermeable membrane, and a selectively permeable membrane. During your next exam, you may begin to sweat a solution of sodium, chloride, and water, but not proteins, sugars, or nucleotides. Are the membranes of your sweat gland cells freely permeable, impermeable, or selectively permeable?arrow_forward
