Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
Answer;
-Arousal, metabolism, growth and sex
The endocrine system is directly involved with arousal, metabolism, growth and sex.
Explanation;
The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
-These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function. The hormones are released into the bloodstream and may affect one or several organs throughout the body.
-Hormones are chemical messengers created by the body, whose role is to transfer information from one set of cells to another to coordinate the functions of different parts of the body.
