Cell Communication Crossword

A set of chemical reactions in a cell that occurs when a molecule attaches to a receptor on the cell membrane
A system of stimuli and response correlated to population density
A form of cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells
A release of hormones that act on distant target cells in the body
Similar to paracrine signaling but there is a special structure called the synapse between the cell originating and the cell receiving the signal
A chemical substance produced in the body that controls and regulates the activity of certain cells or organs
When the target cell detects a signal, usually in the form of a small, water-soluble molecule, via binding to receptor protein
The process by which foreign DNA is introduced into a cell by a virus or viral vector
Any behavior of a living organism that results from an external or internal stimulus
Usually a molecule which produces a signal by binding to a site on a target protein
Act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior
Constitute a large protein family of receptors, that detect molecules outside the cell and activate internal signal transduction pathways and, ultimately, cellular responses
Guanine Triphosphate
Guanine Diphosphate
Refers to the reversible transition of a molecule into a nearly identical chemical or physical state
High-affinity cell surface receptors for many polypeptide growth factors
A phosphate group is added
They pass the message to the next signaling component in the chain without otherwise participating
A group of transmembrane ion channel proteins which open to allow ions through the membrane in response to the binding of a chemical messenger
Kinase enzyme that modifies other proteins by chemically adding phosphate groups to them
A phosphate group is taken away
A sequence of events where one enzyme phosphorylates another, causing a chain reaction leading to the phosphorylation of thousands of proteins
An enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein
A molecule that relays messages in a cell from a receptor on a cell membrane to the final destination where an action within the cell is to take place
A secondary messenger molecule used in signal transduction and lipid signaling in biological cells
A glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages
A mechanism leading to multiple copies of a chromosomal region within a chromosome arm
Interact and/or bind with multiple members of a signaling pathway, tethering them into complexes
A process of programmed cell death that occurs in multicellular organisms
Protrusion of the plasma membrane of a cell
