(a) Describe the structure of the plasma/cell membrane. (b) Describe its function. Explain the chemical composition of cellular membranes related to the function of the cell membrane. What is the cell membrane and what is its function?
Why does the Krebs cycle occur in aerobic cellular respiration? Why is cellular respiration considered to be much more efficient than glycolysis alone? Why do plants use carbohydrates to store their energy instead of ATP? Explain how the structure of the cell plasma membra...
The perigranular membranes fuse with the plasma membrane and the granules exchange their stored histamine for the extracellular sodium which enters the invaginations with the water. The histamine is then equilibrated with the external medium. A number of alternative mechanisms and testable corollaries ...
These are the properties that have most likely determined the evolutionary fate of Archaea and it may be possible for bionanotechnology to adopt these from nature. In this work, we use molecular dynamics simulations to assess at the atomistic level the structure and dynamics of a series of model...

The cell cycle is important to produce cells for the body. One cell is divided to form many cells which can function to repair, grow and heal different tissues in the body. An excess of the cell cycle can cause cancer as too many cells can feed on the nutrition of h...
During host infection, Toxoplasma gondii and related unicellular parasites move using gliding, which differs fundamentally from other known mechanisms of eukaryotic cell motility. Gliding is thought to be powered by a thin layer of flowing filamentous (F)-actin sandwiched between the plasma membrane and...
Finally, we demonstrated that artificial glycosylation of the wild type FXYD2 is reduced when co-expressed with FXYD2-G41R. These data indicate that binding of FXYD2-G41R to wild type FXYD2 subunit might abrogate the routing of wild type FXYD2 to the plasma membrane thus causing the ...
Describe the structure and function of basophil cells. Explain the general functions and locations of the adipose tissue in the body. List the cells that form the epidermis and describe their functions. Explain the function of plasma cells. ...
Explain how the structure and properties of phospholipids help to maintain the structure of the cell membrane. Cell Membrane: All living cells have a cell membrane. It is the barrier between the inside and outside of a cell. Some cells also have a str...
