Describe the structure of the cell membrane

Biology
1 answer:
raketka [301]3 years ago
5 0

Answer:

The cell membrane is a fluid matrix made of a phospholipid bilayer. Each lipid molecule has a hydrophilic, phosphorylated "head" and a hydrophobic, fatty acid "tail". The hydrophobic parts of the molecules on the bilayer face each other, whereas the hydrophilic parts form the inner and outer surfaces of the cell membrane. Small, hydrophobic molecules can traverse the cell membrane via simple diffusion.

Integrated into the membrane are protein molecules which may span the whole bilayer (and are thus known as transmembrane proteins) or just one layer. Some of these proteins act as channels for transport of ions and other particles that can not simply diffuse across the membrane.

What causes the dangerous red tides in the ocean?
Leto [7]

<span>Red tides are formed by dinofllagelata, eucaryotic flagellate organisms. Dinoflagellates are marine plankton which means they drift on the surface of the sea. Those are small, nonmobile organisms who sometimes bloom in concentrations of more than a million cells per ml. The bloom is often red colour so the phenomenon is called red tides. </span>Under such circumstances, they can produce toxins, dinotoxins<span> which are capable of killing fish, so that's why this occurrence is dangerous.</span>
