Movement of cells are important since some cells depends on movement to carry out its major function. For example, sperm cells need to move from one place to another place to carry out reproduction. Movement of cells are supported by cytoskeleton system of the cells. The cyctoskeleton system are composed of microtubules, microfilaments and intermediate filaments. However, for unicellular organisms such as Paramecium, the movement of cells are regulated through cilia or flagella. Cilia can be…

mass of the curd would increase if more acid were to be added to the milk. Background Information The major proteins found in milk, casein and whey, are great at providing all the important amino acids. The only difference between the two is that whey is a quick digesting protein and casein is slow digesting. Whey is beneficial because it provides fast amino acids, resulting in fast protein synthesis. Casein, however, has a longer lasting effect than whey. There was a study done where healthy…

1. Given the following amino acids, explain where they would be found in the tertiary structure of a protein and WHY (lack of explanation/incorrect explanations will NOT receive full credit; assume living system of pH = 7.4). Arg Phe Pro Glu His Ala Tyr Val Cys Arginine: This is a charged amino acid that is extremely hydrophilic. It is hydrophilic because while it has an aliphatic side chain that is hydrophobic, it also has two groups where a positive charge resonates between the two…

Beetroot tissues will be the model investigated in this lab. Specifically the effects of temperature stress on the beetroots cellular membrane. Beetroot is known as Beta Vulgaris, it is one of the healthiest vegetables one can eat with plenty of minerals and vitamins. One of the main vitamins in beetroot is betaine which serve as organic osmolytes that are synthesized or taken from the surroundings by the cells to protect against osmotic stress, high temperature or, drought. Roots of beet also…

removed and a covalent bond is formed. Breaking this bond is called hydrolysis, it is the the addition of a water molecule and releases energy. Examples of macromolecules would be nucleic acids, proteins, and polysaccharides (2 or more sugars). The biological components are composed of starches, proteins, lipids, and nucleic acids. Starches consisit entirely of glucose monomers and are joined by glycosidic linkages, only found in plants. Lipids are a large group of biological molecules that…

OBJECTIVE For the first week of the lab, the objectives were to isolate and test for the presence of major components of milk, including proteins, carbohydrates, fats, vitamins, and minerals and to determine the presence of the various components of milk in the various fractions using qualitative tests for these substances. For the second week of the lab, the there were three objectives that related to the procedure: to determine the calcium concentration of milk using the technique of…

Project Summary Hypothesis Statement: The Atypical Protein Kinase C Zeta (PKMz) is the molecular mechanism underlying Long Term Potentiation (LTP) maintenance at the synaptic membrane. Furthermore, this process is regulated at the level of translation of a locally available pool of PKMz mRNA, and can be sustained in part by active PKMz itself, or inhibited via an activity-dependent translation block. Significance: If the effects of a true PKMz conditional knockout result in memory impairments…

isomerisation. Introduction Bacteriorhodopsin is a globular protein, (Henderson, 1975) which acts as a light driven proton- pump located in the native purple membrane of Halobacterium halobium. It was first discovered by Stoechenius and his lab in 1979 (Stoeckenius, 1979). Although Henderson and Unwin had already made a three-dimensional map of…

ferns, monocotyledons and dicotyledons which bind to proteins to form a compound known as tannin protein complex (T-PC). (R. Osawa et al, 1995). This protein complex is not easily broken down by enzymes in the mammalian digestive track. For a native species such as the koala (Phascolarctos cinereus), being an herbivore, they have a selective diet consisting entirely of Eucalyptus foliage. Eucalyptus leaves have a low source of available protein and carbohydrates (C.J. Barker et al, 2013) but…

Benzimidazole and its derivatives were synthesized according to the reported literature (Wagner EC et al., 1943). The compounds are benzimidazole ;1-(4-((1H-benzimidazol-1-yl) methylamino) phenyl) ethanone; 2-butyl-1H-benzimidazole; 2-methyl-1H-benzimidazole. The stock solutions are prepared by dissolving the compound in DMSO. Antimicrobial activity was tested by the disc-diffusion method under standard conditions using Mueller-Hinton Agar (MHA) and the antibiotics used as listed below, Table…
