5649972694 | ligand | binds to the receptor on the plasma membrane | 0 | |
5649972695 | kinase | a protein involved in signal transduction that activates other molecules by adding a phosphate group to them | 1 | |
5649972696 | phosphorylation cascade | A phosphorylation cascade is a sequence of events where one enzyme phosphorylates another, causing a chain reaction leading to the phosphorylation of thousands of proteins. This can be seen in signal transduction of hormone messages | 2 | |
5649972697 | reception | first of the three stages of cell signaling | 3 | |
5649972698 | transduction | second of the three stages of cell signaling | 4 | |
5649972699 | response | last of the three stages of cell signaling | 5 | |
5649972700 | g-proteins | also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior | 6 | |
5649972702 | ligand-gated ion channels | are a group of transmembrane ion channel proteins which open to allow ions such as Na+, K+, Ca2+, or Cl− to pass through the membrane in response to the binding of a chemical messenger (i.e. a ligand), such as a neurotransmitter | 7 | |
5649972704 | The plasma membrane | Selectively permeable bilayer | 8 | |
5649972705 | blood stream | The path a hormone takes to get to its receptor | 9 | |
5649972706 | Cyclic AMP (cAMP) | is a second messenger that is important in many biological processes. cAMP is used for intracellular signal transduction in many different organisms | 10 | |
5649972707 | Second Messengers | molecules that relay signals received at receptors on the cell surface to target molecules in the cytosol and/or nucleus | 11 | |
5649972709 | Apoptosis | Programmed cell suicide | 12 | |
5649972710 | phosphatases | how a signal transduction pathway is turned off; inactivates kinases | 13 | |
5649972713 | Apoptosis mainly prevents what disease? | Cancer | 14 | |
5649972718 | the protein kinases and phosphatases are both types of... | enzymes | 15 | |
5649972721 | transcription factor | a regulatory protein that binds to DNA, affecting the transcription of specific genes | 16 | |
5650035570 | Quorum sensing | a system of communication among bacteria that uses population density | 17 | |
5651436327 | Evolution and cell communication | Similar cell signal pathways are seen in diverse organisms; evidence that | 18 |
