The phospholipid bilayer functions mainly as a structural framework for the membrane where the polar heads of the phospholipids tend to orient towards their polar surroundings, preserving the hydrophobic part from any contact with water.
<h3>What are phospholipids?</h3>
They are lipid molecules that have a strongly polar group in addition to the hydrophobic hydrocarbon chain.
<h3>Characteristics of phospholipids</h3>
- The polar heads are oriented towards the aqueous medium (intra and extracellular).
- The hydrophobic tails tend to be oriented towards the lipid medium, that is, inside the bilayer, constituting the membrane matrix.
Therefore, we can conclude that phospholipids, due to their amphipathic nature, tend to orient or organize themselves spontaneously, forming the so-called lipid bilayer.

Answer:
Explanation:
<em>Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.</em>
Answer:The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood
Basically, the FSL states that the greater the stroke volume of the left ventricle will increase, as the volume of the the ventricles increases due to ventricular contraction, leading to systolic contraction.
If the volume of the blood in the Ventricle is increased, the blood volume stretches the ventricular walls and the ventricle contracts.The amount of blood ejected from the ventricle increased(stoke volume).Therefore, the higher the contraction of the ventricles, Myocyte stretch, the more the volume of blood in the ventricle pushed, and the more the amount of the blood ejected from the ventricle as Stroke Volume.
