Answer:
The correct answer is E. Arachidonic acid is the raw material for synthesis of eicosanoids.
Explanation:
Arachidonic acid is an essential omega-6 fatty acid formed by a 20-carbon chain with four double bonds. The presence of double bonds causes this molecule to have several sites that can be oxidized, allowing the formation of different lipids with different biological activities.
Arachidonic acid is part of phospholipids in cell membranes, and is the precursor of eicosanoid biosynthesis. Arachidonic acid can be synthesized from linoleic acid, one of the essential fatty acids required by most mammals.
Answer:Muscle cells are able to produce ATP with oxygen, which is called aerobic respiration, or without oxygen, an anaerobic process called anaerobic glycolysis or fermentation. The process in which ATP is made is dependent on the availability of oxygen (see the Cellular Respiration concepts).
Explanation:
If thousands of glucose molecules were bonded together with equal numbers of sucrose molecules, the resulting substance could be described as a polysaccharide. They are <span>polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages.</span>
