What chemical messengers can pass through the plasma membrane and effect receptors in the cytoplasm?

Primary messengers are hormones (extracellular molecules) that conduct the signalling events by not passing though the membrane but binding on the cell surface receptors. Secondary messengers are small molecules that may cross the membrane which actually conduct the downstream signalling events inside the cell (intracellular). cAMP, cGMP, calcium ions, inositol triphosphate are a few secondary messengers. cell proliferation, differentiation, migration, metabolism, cell death such as apoptosis events are all controlled by signalling pathways.

What are chemical messengers that pass through the plasma membrane of cells and have receptor molecules in the cytoplasm?
mitochondria
The molecules in the cell membrane that serve as receptors or binding sites for hormones or other chemical messengers are?
Proteins.Answer found in Eighth Edition of Essentials of Human Anatomy and Physiology by Elaine N. Marieb
Only those who have the proper on the cell membrane are activated by the chemical messengers?
Target Cell
Why does most amino acid based hormones bind to cell membrane receptors?
This is because they do not have the ability to pass through the membrane, unlike steroid hormones. Steroid hormones bind inside the cell cytoplasm before docking onto the receptors.
What do nucleus cytoplasm and cell membrane do to the cell?
Cell membrane controls the movement into or out of the cell. Nucleus controls all activities of the cell Cytoplasm a place for storing food and material,chemical reactions take place here.
Why some steroid hormones do not require a membrane receptor?
Because they are lipid soluble and therefore are readily diffusable across the cell membrane. Their receptors are found within the cytoplasm or nucleus
What does cytoplasm have in it?
Cytoplasm is a jelly like fluid between the cell membrane and nuclear membrane.In cytoplasm chemical reactions take place ,these reaction are collectively known as metabolism.
What does NOT influence the rate of diffusion of a chemical across a plasma membrane?
Besides the concentration of the chemical, the pore size of the plasma membrane, and the osmotic pressure of the cytoplasm - nothing else influences the rate of diffusion of a chemical across a plasma membrane.
What is the fluid within the cell's outer membrane and is also the site of many chemical reactions?
cytoplasm
What are activities are performed by membrane proteins in multicellular organisms?
Chemical messengers to send information move molecules in and out of cells
What do intracellular receptors do?
The intracellular receptors differ from membrane receptors based on their location. Membrane receptors are usually on the plasma membrane but the intracellular receptors are found inside the cell.
What is the region between the cell membrane and the nucleus called?
cytoplasm is located between the cell membrane and the nucleus.
