A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails. ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water .
Skeletal muscle or striated muscles is an important part of the human motion system. These muscles will contract and relax so as to move the bones in the body movement.<span>Bones as a means of passive motion was not able to move without the muscle as a tool motion.</span>
The energy of the electrons in NADPH are not sufficient for anabolic reactions such as CO2 fixation. These processes also require biochemical energy in the form of ATP. The process of photosynthetic electron transfer also generates a gradient of protons (H+) across the photosynthetic membrane (Figure: Proton Gradient).
