*Ligand specific for receptor! *Cells are genetically identical. Can be inside or outside of the cell - *if small and non-polar (steroid), inside; if large and polar, outside. Chromosomes become visable, nuclear envelop dissolves, spindle forms.

The transfer of a phosphate group, usually from ATP, to a molecule. On or in a cell, a specific protein to whose shape fits that of a specific molecular messenger, such as a hormone. Enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle. Period of the cell cycle between cell divisions. Match.

The strengthening of stimulus energy during transduction. *Crossing over! A small, nonprotein, water-soluble molecule or ion, such as a calcium ion (Ca2+) or cyclic AMP, that relays a signal to a cell's interior in response to a signaling molecule bound by a signal receptor protein. A mechanism of response in which a stimulus initiates reactions that reduce the stimulus. A protein that binds to a specific signal molecule, enabling the cell to respond to the signal molecule. reyesa2023. A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level. large relay protein that may bind with several other relay proteins to increase the efficiency of a signaling pathway, enzyme attached to the plasma membrane that converts ATP to cAMP in response to an extracellular signal, enzyme that may be activated by a G protein or tyrosine-kinase receptor and cleaves a plasma-membrane phospholipid into the second messengers IP3 and DAG, relay protein attached to the inside of plasma membrane that, when activated by an activated G-protein-linked receptor, bind GTP and then usually activates another membrane-attached protein, Which signal molecule passes through the plasma membrane, binds to intracellular receptors that move into the nucleus, and function as transcription factors to regulate gene expression. A small, nonprotein, water-soluble molecule or ion, such as a calcium ion (Ca2+) or cyclic AMP, that relays a signal to a cell's interior in response to a signaling molecule bound by a signal receptor protein.

Is not useful in maintaining homeostasis as the process pushes away from the target set point. Cell division in which the nucleus divides into nuclei containing the same number of chromosomes. Feedback that tends to magnify a process or increase its output.

12 terms. Enzyme cascades amp the cell's response to a signal.

Any molecule that catalyzes a reaction can do so multiple times producing more than one product molecule.
