Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy.
Report Abuse. Afferent pathways send information to your central nervous system (CNS), or peripheral nervous system (PNS). Efferent pathways send signals from those two locations to your muscles. Taste, sight, hearing, etc. are all afferent pathways. A reflex arc, or simply reflex, is then caused by an afferent pathway signaling to the PNS (Spinal cord), which then immediately signals muscles to react.
signal transduction pathway. A series of steps linking a mechanical or chemical stimulus to a specific cellular response. There are four types that we studied: g-protein linked reception; hormonal reception; receptor tyrosine kinase reception; pathways using second messengers (cAMP; calcium ions).econd messenger. 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.
