Nuclear envelope What genetic material is found in this part of the cell more than anywhere else in the cell? RNA C. Nucleolus D. Cytoplasm E. Mitochondria F. Lysosomes G. Endoplasmic Reticulum H. Golgi apparatus I. This part of the cell is reponsible for breaking down organic molecules. J. Ribosomes K. centrioles L. Chromatin What function do peroxisomes serve? Peroxisomes contain a variety of enzymes, which primarily function together to rid the cell of toxic substances, and in particular, hydrogen peroxide (a common byproduct of cellular metabolism).
• What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur? The role of the citric acid cycle is to turn pyruvic acid into ATP and giving off CO2. This happens inside of the mitochondria.
1.Explain what Mucor is and how a patient is likely to become infected with Mucor. Describe the pathophysiologic progression of the infection into pneumonia and at least two medical/nursing interventions that would be helpful in treating the patient. Mucor is a microbial genus of moulds commonly found in soil, digestive systems, plants surfaces and rotten vegetable matter. There are two main types of infection that people can get from mucor and these depend on the route of exposure. In the pulmonary exposure occurs by inhaling fungal spores from the environment.
The causative agent of the Bubonic Plague is a gram-negative coccobacilli shaped bacteria, Yersinia pestis. Yersinia pestis belongs to the family of enterobacteria and is a facultative anaerobe. Metabolism of Yersinia pestis is fermentative, and produces a thick capsule, which prevents the ability of white blood cells to ward of the infection of Yersinia pestis. There are three known diseases that are caused by Yersinia pestis; Bubonic, Septemic, and Pneumonic Plague. Bubonic plague is an infectious disease that is transmitted from small rodents and their fleas to
Glycolysis plus the citric acid cycle can convert the carbons of glucose to _________ , storing the energy as ATP, _____________ and ___________. * B. pyruvate, lactic acid, CO2, NADH, FADH2 2. At the end of glycolysis, each molecule of glucose has yielded 2 molecules of _______, 2 molecules of ________, and a net of 2 molecules of _________. * D. pyruvate; NADH; ATP 3. Trematol is a metabolic poison derived from the white snake root.
Which of the following statements is correct concerning biotin. A. Intestinal biotinyl carboxylase cleaves biotin from biotin-containing proteins B. Biotinidase cleaves biocytin to yield biotin C. The first step in the intestinal digestion of biotin –containing proteins is the oxidation of the valeric side chain D. A and B E. B and C 8. Identify
Controlled Variables. temperature; pH; sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. The amount of product produced is an indicator of sucrase activity. This is an indicatore because sucrase is an enzyme found in the small intestine that catalyzes the splitting of the disaccharide sucrose into the monosaccharides glucos and fructose.
The energy for this process is supplied by the hydrolysis of ATP using the enzyme ATPase and a specific protein channel in the membrane. Active transport is the movement of substances from where they are less concentrated to where they are more concentrated. It is undertaken by carrier proteins in cell membranes, which move specific molecules or ions against the concentration gradient using energy supplied by ATP. Cells have many adaptations to allow them to facilitate active transport; they may have carrier proteins in the cell surface membrane designed to transport particular molecules or ions or possess many mitochondria to supply the required ATP. Active transport requires energy in the form of ATP and protein carriers to move the molecules across the membrane.
What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012). MICROBIOLOGY: A SYSTEMS APPROACH, THIRD EDITION.
Fat is also store in the system as triglycerides that forms three of our good saturated fatty acids. This process is formed on the cellular level of respiration. Adenosine triphosphate is our main source of receiving energy to the body. 1. Describe how the storage of molecules is broken down and used to produce ATP.
