Proteins on the cell surface that bind specific signaling molecules (ligands).

A signaling molecule that binds to a receptor.

Cell surface receptors can be categorized as ion channels, G protein-coupled receptors (GPCRs), enzyme-linked receptors, or integrins.

Receptors located inside the cell (cytoplasm or nucleus).

Receptors specifically bind to molecules, initiating cellular responses.

The processes by which cells receive and respond to signals from their environment, leading to changes within the cell.

The maintenance of a stable internal environment in an organism

The ability of cells to receive and respond to signals from other cells or the environment.

Different ways cells communicate, including hormones, neurotransmitters, and others.

How cells recognize and detect specific signals.

The process of decoding and understanding the meaning of a signal a cell receives.

The cellular components that execute the response to a signal, like proteins and enzymes.

A medication used to treat erectile dysfunction, by increasing blood flow to the penis.

Protein G activation occurs by binding to GTP, triggering downstream cellular responses.

The intrinsic ability of a protein to hydrolyze GTP, leading to its own inactivation.

Specific type of protein G activated upon binding to GPCRs (G-protein coupled receptors).

A simpler form of protein G, which activates upon binding to different kinds of membrane receptors.

A protein that accelerates the activation of monomeric protein G.

A protein that accelerates the inactivation of trimeric protein G by enhancing GTP hydrolysis.

A protein that accelerates the inactivation of monomeric protein G by enhancing GTP hydrolysis.

Proteins that act as organizing centers for signaling pathways, bringing together multiple activated proteins.

The processes inside a cell by which signals are transmitted from one component to another, leading to a specific cellular response.

Cell surface receptors that directly catalyze a reaction after binding to a signal, initiating a cellular response.

A signaling pathway that regulates cell growth, differentiation, and survival.

A pathway activated by cytokines and similar signaling molecules, affecting gene expression and cell function.

Receptors inside the cell, often in the cytoplasm or nucleus, that bind small, hydrophobic ligands.

Small, hydrophobic molecules that can cross the cell membrane and bind to intracellular receptors.

The process by which multiple signals are combined to produce a unified response.

Proteins that organize signaling molecules into complexes facilitating proper signal transduction.

The process of maintaining a stable concentration of dissolved substances (osmolarity) in the body fluids.

A hormone that regulates water reabsorption in the kidneys, helping control blood osmolarity.

ADH receptors in the kidneys that trigger water reabsorption.

The concentration of dissolved particles, like salt, in the bloodstream.

ADH receptors that cause blood vessel constriction (vasoconstriction).

The maintenance of proper water levels in the body.

A hormone that regulates sodium and potassium levels in kidneys.

Maintaining appropriate levels of essential ions (electrolytes) in the body.

ADH increases water reabsorption in the kidneys, reducing plasma osmolarity (returning it to 280 mOsm/L) and promoting water retention by the body.

Aldosterone secretion is triggered by low blood pressure (renal hypotension), high potassium levels (hyperkalemia), low sodium levels (hyponatremia), and factors like stress.

Membrane channel proteins that facilitate water movement in and out of cells.

Aldosterone, a steroid hormone, binds to intracellular receptors and, after translocation to the nucleus, alters gene transcription, leading to protein production.

Cells of the nephron, a functional unit of the kidney; they regulate water and electrolyte balance.

The process of taking back water from the filtrate in the kidney tubules.

The concentration of solutes in the blood plasma.

A crucial hormonal system regulating blood pressure, and impacting aldosterone secretion.

Membrane-bound vesicles carrying molecules, such as aquaporins, for transport into or out of the cell.
