Holocrine
Sebaceous glands secretion contains cell fragments. Sweat gland apocrine produce a secretion containing proteins and fats in addition to water and salts.
The cell membrane of animal cells contains which lipid not seen in plant cells is cholesterol. Cholesterol will not form a membrane by itself.
Yes, lysosomes contain a wide variety of enzymes that help to digest nutrients.
The lipid bylayer of the cell membranes is made of phospholipids which are hydrophilic heads and hydrophobic tails. The phospholipids are impermeable to ions such as salts, so the bilayer contains protein channels that allow the cell to regulate which molecules can enter the cell.
The plasma membrane is made up of phospholipids, each of which contains a glycerol molecule bonded to a phosphate group and two fatty acids.
"Analysis of a glandular secretion indicates that it contains some DNA, RNA, and membrane components such as phospholipids. What kind of secretion is this, and why?"
Pancreas
Sebaceous glands secretion contains cell fragments. Sweat gland apocrine produce a secretion containing proteins and fats in addition to water and salts.
The cell membrane contains phospholipids.

A
Mucous. It contains lactoferrin which binds the iron that the bacteria needs.
Aprocrine
Apocrine Sweat Glands.
