FUNCTIONS OF PLASMA MEMBRANE
content.patnawomenscollege.in-'The cell membrane maintains the physical integrity Of the cell. It's most obvious in the cases Of animal cells (because they don't have cell walls) that the cell membrane holds the cell together by enclosing the cytoplasm and organelles within it. 'The cell membrane forms a barrier between the inside Of the cell and the
1 Introduction to cell biology
biomechanics.stanford.eduThe structural integrity of the cell is maintained by a complex network of tensile and compressive one-dimensional elements, the cytoskeleton. The cytoskeleton is the cel-lular scaffold which maintains cell shape ... The cell membrane thus has to be strong enough to prevent the explosion of the cell. Plant cells and most bacteria have found an ...
Diffusion, Osmosis, Active Transport
biologymad.comSodium/potassium pump in cell membranes (especially nerve cells) Endo/exocytosis This is the movement of very large molecules (or particles, bacteria or other organisms) across the cell membrane. It involves the fusion of vesicles (containing the target/victim) with the cell membrane e.g. bacteria entering macrophages. Substances destined

www.sd27j.orgPassive Transport Across the Cell Membrane Passive transport describes the movement of substances down a concentration gradient and does not require energy use. • Bulk flow is the collective movement of substances in the same direction in response to a force, such as pressure. Blood moving through a vessel is an example of bulk flow.

The precursor is then linked to a lipid-like carrier in the cell membrane (bactoprenol) and N-acetyl glucosamine (NAG) is added to the NAM. This ... the need for transport mechanisms across this membrane.
