What else can I help you with?
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.
Hormones attach to plasma membrane proteins called?
Hormones attach to plasma membrane proteins called receptors. These receptors can trigger signaling pathways within the cell when activated by the hormone binding.
Does cholesterol function as a hormone receptor in the plasma membrane?
No, cholesterol does not directly function as a hormone receptor in the plasma membrane. Hormone receptors are typically proteins embedded in the membrane that bind specific hormones to initiate signaling pathways. Cholesterol primarily provides structural support and fluidity to the plasma membrane.
What are the specializations of the plasma membrane?
The plasma membrane specializes in controlling the movement of substances in and out of the cell through selective permeability. It also plays a role in cell communication and recognition through protein receptors embedded in the membrane. Additionally, the plasma membrane helps maintain the cell's shape and structure.
When large molecules bind to receptors on the plasma membrane and are then engulfed by cell the process is called what?
Receptor-mediated endocytosis :)

Hormones attach to plasma membrane proteins called receptors. These receptors can trigger signaling pathways within the cell when activated by the hormone binding.
What are the differences between receptor desensitization and down regulation?
Desensitization is where the receptors become phosphorylated and therefore inactive but remain on the plasma membrane. Down regulation is any scenario where there are less numbers of receptors on the plasma membrane. So this can include internalization.
What happen if there is a damage to receptors on the plasma membrane?
Plasma membrane defines the boundary of the cell and regulates the flow of material into and out of the cell. Ruptured plasma membrane generally heals within no time but if rupturing does not heal, the cell contents will spill over and cell is killed.
Does cholesterol function as a hormone receptor in the plasma membrane?
No, cholesterol does not directly function as a hormone receptor in the plasma membrane. Hormone receptors are typically proteins embedded in the membrane that bind specific hormones to initiate signaling pathways. Cholesterol primarily provides structural support and fluidity to the plasma membrane.
What would happen if there were damage to the receptors on the plasma membrane?
Plasma membrane defines the boundary of the cell and regulates the flow of material into and out of the cell. Ruptured plasma membrane generally heals within no time but if rupturing does not heal, the cell contents will spill over and cell is killed.

Protein in the plasma membrane not so?
Proteins in the plasma membrane play essential roles in cell adhesion, signaling, and transport. They help regulate the passage of molecules in and out of the cell and serve as receptors for various signaling molecules. Overall, proteins in the plasma membrane are crucial for maintaining cell structure and function.
Which hormone initiates biological action by crossing the plasma membrane and then binding to a receptors?
Steroid hormones such as estrogen, testosterone, and cortisol initiate biological actions by crossing the plasma membrane and binding to receptors inside the cell. This binding activates gene transcription and protein synthesis that lead to various cellular responses.
How does nutrients enter a cell?
The plasma membrane.
