Given that the cytoplasmic membrane has a fluid dynamic nature, with phospholipids and proteins able to move about within the bi
layer structure, what force or structure keeps the membrane from falling apart? A) hydrophilic/hydrophobic forces
B) osmosis
C) rigid sterol lipids
D) the proton motive force
The cytoplasmic membrane consists of phospholipids which have both the hydrophilic and hydrophobic regions and hence are amphipathic in nature. Due to this structural complexity, phospholipids produces barrier both at the interior and exterior of cell and hence form a membrane bilayer under suitable conditions. For instance when it is in water, it arrange itself in a way that their hydrophobic tails lie at the inner side and hydrophilic heads face outer side.
binary fission - asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
