there are four main parts of the plasma membrane of a cell.
1) the lipid bilayer: this is made up of amphipathic molecules, with the polar heads on the outsides and the non polar tails in the middle. this part is semi-permeable.
2) the proteins: these work as canals to pump larger molecules through the bilayer which couldn't otherwise fit.
3) the carbohydrates: these are different on each cell and are used as the "chemical id tag" for identifying other cells.
4) the cholesterol: this is used to keep the lipid bilayer as plasma instead of turning into a solid.
hope this helps (:

What is the surface composition of the sun?
It is composed of superheated hydrogen and helium plasma.
What is the composition of the photosphere?
Hydrogen gas in a plasma state is the main component
Plasma is closest in composition to?
Plasma is closest in composition to the Sun, being made up of mostly electrons and positively charged ions. It is the fourth state of matter, commonly found in stars, lightning, and neon lights. Unlike gases, plasma conducts electricity and responds to electromagnetic fields.
What is the composition of 1 drop of blood?
a. plasma b. leukocytes c. thromboses d. erythrocytes
Does cerebrospinal fluid have the exact same composition as blood plasma?
No, cerebrospinal fluid (CSF) does not have the exact same composition as blood plasma. CSF is produced by the choroid plexus in the brain and is an ultrafiltrate of plasma with lower protein and glucose levels but higher chloride concentrations. Additionally, CSF plays a role in cushioning the brain and spinal cord, as well as removing waste products.
What is the percent of composition in plasma?
Plasma is approximately 91% water and 7% proteins, including albumin, globulins, and fibrinogen. The remaining 2% includes nutrients, electrolytes, hormones, gases, and waste products.
What four materials are carried in plasma?
The four components carried in plasma are water, salts (electrolytes), proteins (such as albumin and globulins), and hormones (like insulin and adrenaline). Plasma also transports waste products, nutrients, and gases throughout the body.
Could milk be used as blood plasma?
No, milk cannot be used as a substitute for blood plasma. Blood plasma contains a different composition of proteins, electrolytes, and other components crucial for bodily functions that are not present in milk. Using milk as a replacement for blood plasma could have serious health implications.
Who invented the thermal plasma analyzer?
The thermal plasma analyzer was invented by Dr. George C. Tisone in the 1970s. It is a specialized instrument that is used to analyze the chemical composition of high-temperature plasmas.
