Cell Membrane Characteristics

Cell Membrane Characteristics

Which of the following is not a characteristic of the plasma membrane? There is a large range of cell membrane characteristics. These characteristics may be affected by the cytoskeleton. For example, disruption of the cytoskeleton decreases the force needed to elongate a membrane tether. Also, the glycocalyx, a network of proteoglycans and glycosaminoglycans covering the cell membrane, may influence the properties of membrane tether formation.

How Diverse Are Cell Membranes?

Cell membrane characteristics are dependent on the type of cell and the composition of its organelles. For example, the cytoplasmic membrane is six to 10 manometers thick and contains lipids, proteins, and carbohydrates. Scientists have tried to model cell membranes using the “model of the fluid mosaic”, which was first proposed by Singer and Nicolson in 972. The Singer and Nicolson model suggested that the cytoplasmic membrane is made of three layers separated by two external lines. The outer layer is thinner than the inner one and the innermost layer is thicker.

The cellular state of a cell can be assessed using various solid techniques. Quantitation of surface markers is a pivotal method to evaluate the cellular state of cells. This can be achieved by measuring the phospholipid content of the cellular membrane. This method can also be used to assess cellular membrane homogeneity.

LAs have been shown to alter cell membrane properties. In one study, Tsuchiya et al. found that LAs increased membrane fluidity. In another study, Sugahara et al. investigated changes in the thermodynamics of lipid membranes in the presence of LAs and found that the LDC induced more gA than TTC.
