Phospholipid

described like a sausage-shaped structure. It has a double membrane and it controls what enters and exit’s the mitochondria. It has the outer membrane and the inner membrane. Outer membrane are described smooth and is composed of equal amounts of phospholipids and proteins. The inner membrane is more complex and is folded into a number of folds called cristae. It increases the available surface area where respiratory processes take place. The rest is called the matrix. In length the…

Surfactant Agents I. Definitions a. Surfactant: A surface-active agent that lowers surface tension i. Examples 1. soap 2. detergent b. Surface Tension: Force caused by attraction between like molecules that occurs at liquid-gas interfaces and that holds the liquid surface intact i. Units of Measure: dynes/centimeter (dyn/cm) 1. the force required to cause a 1 cm rupture in the surface film ii. a droplet forms because a liquid’s molecules are more attracted to each other than the surrounding…

The membrane serves as a holding site for the catalytic enzymes associated with these processes. Textbook Reference: 6.6 What Are Some Other Functions of Membranes? Page: 124–125 TEXTBOOK SELF-QUIZ 1. Which statement about membrane phospholipids is not true? a. They associate to form bilayers. b. They have hydrophobic “tails.” c. They have hydrophilic “heads.” d. They give the membrane fluidity. e. They flip-flop readily from one side of the membrane to the other. Answer: e 2…

Carbohydrates, lipids, proteins and nucleic acids are large biological molecules that play a major role in relation to the structure and function in plants and animals. These organic molecules consist of many examples and functions. Each biological molecule has a unique function and emergent properties that helps contribute to the cellular structure in both plants and animals. These biological molecules are known as macromolecules because they are large and are composed of thousands of atoms.…

to effectively dispose of unwanted substances inside of a cell; this includes excess and faulty organelles, food particles, viruses and bacteria (Micro.magnet.fsu.edu, 2016). These are contained inside of a plasma membrane which are made up of phospholipids and can fuse…

Omega-3 Omega-3 - what is it? Omega-3 is a so-called essential fatty acid - an essential fat that our body can not produce itself. Omega-3 is an important building block in all of our cells, so it is important that we eat food that provides us with sufficient quantities. Omega-3 should be in balance with omega-6, another essential fatty acid. The balance has shifted radically since the omega-3 in our diet decreased while the amount of omega-6 in food increased dramatically. We eat too little…

There are many theories that explain the damage that happens in DOMS at the cellular level. The most known explanation is the accumulation of lactic acid, but this was rejected because it was shown to be unrelated to DOMS. There is the muscle spasm theory that indicates that resting activation of the muscles caused spasm that compressed the vessels, hindering blood flow and increased the sensation of pain. The connective tissue states that there is a predominance of type II fibers that increase…

Support the Endosymbiotic Theory Gianna Melendez Chamberlain College of Nursing Support the Endosymbiotic Theory The endosymbiotic theory proposes that eukaryotes formed from the union of small aerobic prokaryotes with larger anaerobic prokaryotes, which form organelles. The smaller prokaryotes were not destroyed by the larger cells, but instead became internal parasites that remained surrounded by a vesicular membrane of the host. The theory proposed that mitochondria are the…

formation of DNA serves an important role in long-term storage of information. DNA sequences are the blueprint for the composition of biological organisms. The tertiary structure of the membrane is comprised of a lipid bilayer. The amphiphilic phospholipid molecules create an impermeable membrane through hydrophobic interactions. When organic molecules are placed in a polar environment, an endothermic reaction occurs that decreases the entropy of the system (ΔS). Hydrophobic interactions…

Notice: Not a lot of brain cells were damaged in the production of this paper. When this paper first began, I found my opinion about the liver was not the best. I believed that the liver is valuable but only produces waste, which is no fun. However, as I began to research the liver and how it plays a huge part in my daily life it changed my perspective. Most things that humans ingest go through the liver at one point or another. The Liver has the ability to turn ineffective or pointless…
