A phospholipid is that type of lipid molecule which is known as the main component of cell membrane.
Explanation:
Phospholipid is made up with two fatty acid tails as well as head group of phosphate. It is made with long based chains which is made up of with hydrogen and carbon.
It consists with phosphorus molecule with attachment of four oxygen. These component of phospholipid is connected through third molecule glycerol. It is able to form a cell membrane.
<span>Skin in both humans and animals serves to not only protect the organs contained within us but also serves to provide sensation, which allows man and animal alike to perceive and react to external stimuli such as pain and pleasure. Lastly skin serves to regulate body temperature.</span>
Answer:
B) cAMP
Explanation:
Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are are regulators of signal transduction: regulate the duration of signaling pathway.
Caffeine is central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.
Molecules that are hydrophilic (water loving) are capable of forming bonds with water and other hydrophilic molecules. They are called polar molecules. ... Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers.
