Final answer:
Phospholipids are a type of lipid that make up the main structural component of cell membranes. They provide structural integrity, regulate the passage of molecules, and facilitate cell recognition. Hormones are chemical messengers that regulate various physiological processes and maintain homeostasis in the body.
Step-by-step explanation:
Function of Phospholipids in Cells:
Phospholipids are a type of lipid that make up the main structural component of cell membranes. They have a hydrophilic (water-loving) head and hydrophobic (water-repelling) tails. This unique structure allows phospholipids to form a bilayer in which the hydrophilic heads face outward towards water and the hydrophobic tails face inward, creating a barrier that separates the internal environment of the cell from the external environment. The function of phospholipids in cells includes:
Providing structural integrity and stability to the cell membrane.
Regulating the passage of molecules and ions into and out of the cell.
Facilitating cell recognition and communication.
Function of Hormones:
Hormones are chemical messengers produced by the endocrine glands that help regulate various physiological processes in the body. They are released into the bloodstream and travel to target cells or organs, where they bind to specific receptors and elicit specific responses. The functions of hormones include:
Regulating growth and development.
Controlling metabolism and energy balance.
Maintaining homeostasis and the balance of various bodily functions.
Controlling reproductive processes.
