This type of transport requires expending cellular energy and the assistance of proteins (i.e. carrier protein). Transport Definition In general, the term transport is the movement (of something) from one place to another. It can be used as an action word for carrying, moving, or conveying ...
Carrier proteins use a process called carrier mediated transport to move molecules from one side of the membrane to another. This involves binding the molecule and releasing it on the other side of the membrane by changing the shape of the carrier protein. The amino acid sequence of the ...
What is an example of a peripheral membrane protein? An example of a peripheral membrane protein is cytochrome C. It is mostly found at the location of the mitochondrial membrane, where it functions as an electron transfer for the electron transport chain.What...

Primary Structure of Proteins. The linear sequence of amino acids constitutes a protein's primary structure. The sequence is written from the amino-terminal end (the first amino acid) to the carboxyl-terminal end (the same sequence in which the protein is synthesized). All properties of a pr...
They serve a large variety of functions, including structure, transport and defense. Proteins are made of chains of amino acids, and there are up to four levels of structure. Some specific examples of proteins include collagen, insulin and antibodies. Read Protein Molecule | Definition, Function ...
This transport protein functions in cells with a high internal potassium ion (K+) concentration and low internal sodium ion (Na+) concentration (as shown on the right side of the figure). Three sodium ions bind to the active site of the transporter from the interior of the cell (the "int...
