Some hormones enter cells via what?
Some hormones enter cells via specific hormone receptors located on the cell membrane. Once the hormone binds to its receptor, it triggers a series of intracellular signaling cascades that ultimately lead to a cellular response.
Do hormones enter cells through exocytosis or pinocytosis?
Hormones typically enter cells through specific receptor-mediated endocytosis, a form of pinocytosis. The hormone binds to a receptor on the cell surface, initiating a process in which the hormone-receptor complex is internalized into the cell through vesicle formation. Hormones are not typically released by cells through exocytosis; instead, they are released into the extracellular space to exert their effects on target cells.
How do hormones leave the cell?
Hormones can leave the cell through different mechanisms, such as passive diffusion through the cell membrane or active transport using specific transport proteins. Some hormones may also interact with receptors on the cell membrane and trigger a signaling cascade that leads to hormone release from the cell.
Are hormones transported throughout the whole body?
Yes. Hormones are transported throughout the body, via the bloodstream. They do not, however, effect every cell. Only certain cells in the body have the proper receptor sites to accomodate hormones. Therefore, even though hormones are transported right through the body, they only create a reaction for certain things.
Cells communicate with one another via?
Cells communicate with one another via chemical signaling molecules such as hormones, neurotransmitters, and cytokines. These molecules are released by one cell and bind to specific receptors on the surface of another cell, triggering a response. Cell communication is essential for coordinating processes such as growth, development, and immune responses in multicellular organisms.

Can hormones alter the enzyme activity in cells?
Yes. Hormones may stimulate the reversible covalent modification of an enzyme via phosphorylation or dephosphorylation and alter the activity of the molecule.
Where does the pituitary gland hormones go?
The pituitary gland is endocrine and so all the hormones it produces enter the blood stream. They do this via the circle of willis which is a ring of vessels that's surrounds the gland. As endocrine hormones they travel throughout the body.

What are large protein molecules from its mother's milk that enter the cells lining the baby's digestive tract via?
endocytosis
Which hormone is released when you sleep at night and how does it work inducing sleep?
Hormones are chemical messengers that are secreted by the endocrine glands into the blood. Hormones are transported via the bloodstream to reach specific cells, called target cells, in other tissues. They produce a specific effect on the activity of cells that are remotely located from their point of origin.
How brain control our body?
Via voluntary nerves, via autonomic nerves, and via hormones.
What is the function of the respiratory and circulatorysystem?
Supply fuel and oxygen to the cells, and to remove waste products. They also aid in heat distribution, and information (via hormones) spread.
What types of ligands enter by receptor-mediated endocytosis?
Ligands that enter cells via receptor-mediated endocytosis include hormones, growth factors, and various proteins. These ligands bind to specific cell surface receptors, triggering internalization into the cell through invagination of the plasma membrane and formation of vesicles.
A major difference between neurotransmitters and hormones is that hormones reach their destination via?
blood
