An example of active transport is the sodium-potassium pump in nerve cells. Normally, the concentration of sodium is low in the cell and high outside the cell while potassium concentration is typically high inside the cell and low outside the cell. When a nerve impulse is triggered, sodium ...
Intracellular Transportation Cells are complex structures with many "moving parts" that need to get from one point to another within the cell in order to accomplish metabolic processes. There are specialized organelles in both plant and animal cells that make up the superhighways of a cell. ...

The main difference between active and passive transport is the use of energy during cell transport of materials. Active transport uses energy and passive transport does not. In active transport, molecules are moving against a concentration gradient (or membrane), meaning the cell moves materials fro...
There is a key distinction between active and passive transport. Active transport is the movement of molecules against the gradient, while passive transport is with the gradient. Two differences exist between active vs passive transport: energy usage and
The primary and secondary replicas ping each other to signal that they're still active. Receiving a ping from the other replica during the timeout period indicates that the connection is still open, and that the server instances are communicating. On receiving a ping, an availability replica ...
The metabase for IIS 6.0 is stored in an XML file instead of in binary format as it was in earlier versions of IIS. The location remains the same, but the ways it can be manipulated -- updated, rolled back, restored, and extended -- have changed. There are two significant files ...
The size of the cells ranges between 10–100 µm in diameter. This broad category involves plants, fungi, protozoans, and animals. The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell...
In this release, we've made the following changes: Devices no longer go into idle mode when video playback is active. Improved client logging, diagnostics, and error classification to help admins troubleshoot connection and feed issues. Updates for version 1.2.5248 Date published: Feb...
By volume, half of blood is the liquid part, called plasma. The rest comprises specialised components, the main one being red blood cells (technically known as erythrocytes). These transport oxygen molecules throughout the body, and also give blood its colour (from the hemoglobin protein within...
