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.
Each metabolic pathway consists of a series of biochemical reactions that are connected by their intermediates: the products of one reaction are the substrates for subsequent reactions, and so on. Metabolic pathways are often considered to flow in one direction.
