The different cell membrane transport mechanisms The cell membrane is referred to as a ‘fluid mosaic model’ because the protein part within the cell membrane used to be though of as an even layer spread over the outside and the inside of the phospholipid. Now we are starting to think that it is spread unevenly‚ more like a mosaic than a layer. The phospholipid part of the cell membrane is fluid; this means that its molecules are constantly moving about. Through the molecules constantly moving

The two variables that affect the rate of diffusion are: A. The size of the molecule. The larger molecule will diffuse more slowly than the smaller molecule. B. The nature of plasma membrane. If the membrane is composed of lipid portion.‚ only lipid soluble molecules can pass through while water molecules

Title: The importance of data quality for modelling in transport Data is always the predominant part of a certain engineering research activity. In the transport area‚ it is extremely necessary for scientists‚ engineers and researchers to set up quantitative mathematical models or to adopt suitable modelling to understand a huge amount of transport events and then to solve transport problems. The initial function of a model is to reflect the reality so that researchers can make use of the
