Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentratio...
example of primary active transport. in this process of transportation, the sodium ions are moved to the outside of the cell and potassium ions are moved to the inside of the cell. secondary active transport secondary active transport is a kind of active transport that uses electrochemical ...

Active transport is the transport of materials against a gradient that requires the use of cellular energy. Active transport uses carrier proteins that act as a pump to move ions and molecules across the membrane. The sodium-potassium pump in animals is an example of ...
or even a molecule or an entire other cell (phagocytosis– “cell eating”). Simply put, one layer of the phospholipid bilayer pinches around the desired substance or molecule and eventually forms a vesicle. This can then be passed through the second half of the bilayer and moved throughout ...
and substance use disorders, and comorbidities, such as cardiovascular disease, diabetes, stroke, and cancer, frequently occur [1]. Depression has become a highly concerning public health issue on an international scale. However, due to the complex pathological mechanisms of neurological diseases, fron...
it is to be noted that uncertainties are introduced by the nature of atoms of the radioactive substance under investigation, and these studies are also limited due to the exposure issues for the users. To address the difficulties in analyzing radioactive matter and nuclear materials using synch...
Molecule that is needed in the cell is moved through protein with another substance. Na diffuses back into cell allowing second molecule through. Coupled channel. Active Transport: Coupled Channels Hint: Find Na on your periodic table – what is it? Hydrogen ions (H+) are actively pumped out...
MANUFACTURER OF AN INTELLIGENT FREE-MOVED ZYTOPROTECTIVE ACTIVE SUBSTANCE FOR THE DISPOSAL AND USE OF THE MEDICINAL PRODUCTThe invention describes self-associating biopolymers containing high-molar-mass hyaluronan and chitosan, which together form a carrier for a cytoprotectant L-(+)-ergothioneine, which...
