What else can I help you with?
What binds to receptor molecules on the host cell membrane?
Ligands bind to receptor molecules on the host cell membrane. These ligands can be hormones, neurotransmitters, or other signaling molecules that trigger a cellular response when they bind to their specific receptors.
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.
When large molecules bind to receptors on the plasma membrane and are then engulfed by cell the process is called what?
Receptor-mediated endocytosis :)
A cell that contains proteins enabling a hormone to selectively bind to its plasma membrane is called what?
Target cell
Which cell contains membrane proteins en- abling a hormone to selectively bind to its plasma membrane?
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.

Target cell
The condition that produces inhibition at a synapse is called what?
Neurotransmitters diffuse across the synaptic cleft (a very short distance) and bind to receptor proteins on the postsynaptic membrane. Excitatory neurotransmitters cause sodium ions to move through receptor proteins depolarizing the membrane. Inhibitory neurotransmitters do not depolarize the postsynaptic membrane. Thus, the condition that would produce inhibition at synapse is called HYPERPOLARIZATION.
Which cell contains membrane proteins en- abling a hormone to selectively bind to its plasma membrane?
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.
Which of these extracellular signal molecules could diffuse through a plasma membrane and bind to an intracellular receptor?
Small hydrophobic molecules like steroid hormones can diffuse through the plasma membrane and bind to intracellular receptors, which then translocate into the nucleus to regulate gene expression.
What are membrane proteins that bind to signals by which cells communicate?
Receptors are membrane proteins that bind to signals by which cells communicate. These receptors recognize specific signaling molecules such as hormones, neurotransmitters, and growth factors, and initiate a cellular response upon binding. Examples include G-protein coupled receptors and receptor tyrosine kinases.
What substance on the plasma membrane helps identify chemical signals from outside the cell?
carbohydrates
What protein receives chemical messages for the cell?
The protein that receives chemical messages for the cell is usually a receptor protein. These proteins are located on the cell membrane and can bind to specific signaling molecules, such as hormones or neurotransmitters, to trigger a cellular response.
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
