Where is the receptor for cortisol found?
Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
The outer part of G protein receptor binds and its inner part binds?
The outer part of a G protein-coupled receptor (GPCR) binds to ligands, such as hormones or neurotransmitters, which activates the receptor. The inner part of the receptor interacts with and activates a G protein, initiating downstream signaling cascades within the cell.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
The same receptor can have different effects depending on the properties of the?
ligand that binds to it. For example, a receptor can trigger different signaling pathways or cellular responses if it binds to different ligands, even if they bind to the same binding site on the receptor. This is known as ligand-dependent receptor activation.
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.

What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
What is the machaism of steroid hormone cascade pathway?
The steroid hormone cascade pathway begins when a steroid hormone, such as cortisol or estrogen, diffuses through the cell membrane and binds to its specific intracellular receptor. This hormone-receptor complex then translocates to the nucleus, where it binds to specific DNA sequences, regulating the transcription of target genes. This process ultimately leads to the synthesis of proteins that mediate various physiological responses. The pathway is characterized by its relatively slow onset of action, as it involves changes in gene expression and protein synthesis.
The outer part of G protein receptor binds and its inner part binds?
The outer part of a G protein-coupled receptor (GPCR) binds to ligands, such as hormones or neurotransmitters, which activates the receptor. The inner part of the receptor interacts with and activates a G protein, initiating downstream signaling cascades within the cell.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
The effect of a drug that is an agonist is to?
An agonist binds to a receptor and stimulates it (turns it on). An antagonist binds to a receptor and blocks it from being activated by other molecules (turns it off).
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
The same receptor can have different effects depending on the properties of the?
ligand that binds to it. For example, a receptor can trigger different signaling pathways or cellular responses if it binds to different ligands, even if they bind to the same binding site on the receptor. This is known as ligand-dependent receptor activation.
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
What happens when a single particle binds onto a receptor on the cells surface?
It all depends on the receptor and the particle. Nothing may happen if they don't match up like a lock and key. Or a change in the cell may occur.
What happens when acetycholine binds to its receptor in the sarcolemma and triggers?
When acetylcholine binds to its receptor in the sarcolemma of a muscle cell, it triggers an action potential to be generated along the muscle cell membrane. This action potential then spreads along the sarcolemma and eventually leads to muscle contraction by initiating the release of calcium ions from the sarcoplasmic reticulum.
