Cell Membrane Electron Transport Chain Biochemical Pathway
684 words1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface, and two fatty acid tails hanging from it. The membrane is double, so at the tip of the fatty acid tails, there are two more fatty acid tails attached to another phosphate head. This is what it looks like: The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to the cell: if...

2 H 2 O Creatine Phosphate
1,714 wordsWith the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e. g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate S...

Fatty Acids Blood Glucose
1,749 words... C, and under goes the reactions as described above. The oxidation of FAs yields significantly more energy per carbon than carbohydrates; b-oxidation of one mole of oleic acid (18 -carbon FA) yields 146 moles of ATP; ~ 441 molecules, compared with 114 moles from 18 glucose carbon atoms. Net reaction: Each reaction is specific to the length of the carbon backbone of the fat involved; the overall reaction for the b-oxidation of politic acid (palmitoyl-CoA) may be written as follows: C 16 -S CoA...

Fatty Acids Nerve Fibers
496 wordsThe full name of ALD is Adrenoleukodystrophy. It is a rare X chromosome sex linked metabolic disorder that is characterized by the loss of myelin on nerve fibers within the brain. Myelin is the fatty covering on the nerve fibers. The disease causes the continued degeneration of the adrenal gland. The basic defect is that the impaired capacity to degrade very long chain fatty acids that are found in the blood plasma and tissues of the body. These fatty acids accumulate in the cerebral white matte...

Sodium Hydroxide Petri Dish
1,559 wordsDetection of Biological Molecules Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldnt exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together. Biological mole...

Fatty Acids Saturated Fat
706 wordsCalling fat one of lifes essentials may seem like a bold statement. Health professionals have recommended cutting back on fat for years, cautioning the public about the health risks associated with high-fat eating patterns. However, some types of fats have health benefits, while other fats when eaten in excess have adverse effects. Fat facts: Eating excess amounts of certain fats, notably saturated fat, can increase risk of chronic disease. Unsaturated fats have important functions in the body t...
