Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentrationâin the direction against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport â primary active transport that uses ATP, and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of ...
Cooperation is a word that refers to a process of working in unison, to achieve an objective rather than to work independently to compete with each other. We all know about cooperatives where people pool together resources to have a working system.
As stated above, agonist muscles are muscles that are responsible for causing a certain joint motion. However, the term is often defined incorrectly to mean ALL the muscles that have a role in producing a movement. By this definition stabilizers, neutralizers, and fixators are also agonists.ixator Muscle. A fixator is a stabilizer that acts to eliminate the unwanted movement of an agonist's, or prime mover's, origin. Many muscles are attached to more than one bone. When this happens the muscles are said to be multiarticulate or multijoint muscles.
