| HAROLD KREBS | 1 day ago · Prescribing a low-protein diet (LPD) is part of the standard management of patients in advanced stages of chronic kidney disease (CKD). However, studies on the quality of life (QoL) of patients on LPDs are lacking, and the impact these diets have on their QoL is often given as a reason for not prescribing one. We, therefore, decided to assess the QoL in a cohort of CKD stage 3–5 patients. 2 days ago · Fill out this table summarizing the main differences between aerobic respiration and fermentation (2 marks) Difference Aerobic Respiration Fermentation Location in cell Mitochondria Cytoplasm Reactants Glucose + Oxygen pyruvic acid + NADH Products Carbon dioxide + water Ethanol and carbon dioxide # of ATP produced 36 2.

Microbial metabolism is the means by which a microbe obtains the energy and nutrients e. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the vetween factors in determining that microbe's ecological nicheand often allow for link microbe to be useful in industrial processes or responsible for biogeochemical cycles. How the organism obtains carbon for synthesizing cell mass: [1].
How the organism obtains reducing equivalents hydrogen atoms or electrons used either in energy conservation or in biosynthetic reactions:. Some microbes are heterotrophic more precisely chemoorganoheterotrophicusing organic compounds as both carbon and energy sources. Heterotrophic microbes live off of nutrients that they scavenge from living hosts as commensals or parasites or find in dead organic resipration of all kind saprophages. Microbial metabolism is the main contribution for the bodily decay of all organisms after death. Many eukaryotic microorganisms are heterotrophic by predation or parasitismproperties also found in some bacteria such as Bdellovibrio an intracellular parasite of other bacteria, causing death of its victims and Differdnce such as Myxococcus predators of other bacteria which are killed and lysed by cooperating weber three types of authority of many single cells of Myxobacteria.
Most pathogenic bacteria can be viewed as heterotrophic parasites of humans or the other eukaryotic species they affect. Heterotrophic microbes are extremely abundant in nature and respiratioon responsible for the breakdown of large organic polymers such as cellulosechitin or lignin which are generally indigestible to larger animals. Generally, the oxidative breakdown of large polymers to carbon dioxide mineralization requires several different organisms, with one breaking down the polymer into its constituent monomers, one able to use the monomers and excreting simpler waste compounds as by-products, and one able to use the excreted wastes. There are many variations on this theme, as different organisms are able to degrade different polymers and secrete different waste products.
Some organisms are even able to degrade more recalcitrant compounds such as petroleum the main difference between respiration and fermentation is that respiration or pesticides, making them useful in bioremediation. Biochemically, prokaryotic heterotrophic metabolism is much more versatile than that of eukaryotic organisms, although many prokaryotes share the most basic metabolic models with eukaryotes, e. These basic pathways are well conserved because they are also involved in biosynthesis of many conserved building blocks needed for cell growth sometimes in reverse direction.

However, many bacteria and archaea utilize alternative metabolic pathways other than glycolysis and the citric acid cycle. A well-studied example is sugar metabolism via the keto-deoxy-phosphogluconate pathway also called ED pathway in Pseudomonas. Moreover, there is a third alternative sugar-catabolic pathway used by some bacteria, the pentose phosphate pathway. The metabolic diversity and ability of prokaryotes to use a large variety of organic compounds arises from the much deeper evolutionary history and diversity of prokaryotes, as compared to eukaryotes.
It is also noteworthy that the mitochondrion th, the small membrane-bound intracellular organelle that is the site of eukaryotic oxygen-driven [3] energy metabolism, arose from the endosymbiosis of a bacterium related to obligate intracellular Rickettsiaand also to plant-associated Rhizobium or Agrobacterium. Therefore, it is not surprising that all mitrochondriate eukaryotes share metabolic properties with these Proteobacteria.
Most microbes respire use an electron transport chainalthough oxygen is not the only terminal electron acceptor that may be used. As discussed below, the use of terminal electron acceptors other than oxygen has important biogeochemical consequences. Fermentation is a specific type of heterotrophic metabolism that uses organic carbon instead of oxygen as a terminal electron acceptor. As oxygen is not required, fermentative organisms are anaerobic. Many organisms can use fermentation under anaerobic conditions and aerobic respiration when oxygen is present. These organisms are facultative anaerobes.
To avoid the overproduction of NADH, obligately fermentative organisms usually do not have a complete citric acid cycle. Instead os using an ATP synthase as in respirationATP in fermentative organisms is click by substrate-level phosphorylation where a phosphate group is transferred from a high-energy organic compound to ADP to form ATP. As a result of the need to produce high energy phosphate-containing organic compounds generally in the form of Coenzyme A -esters fermentative organisms use NADH and other cofactors to produce many different reduced metabolic by-products, often including hydrogen gas H 2. These reduced organic compounds are generally small organic acids and alcohols derived from pyruvatethe end product of glycolysis.
Examples include ethanolacetatelactateand butyrate. Fermentative organisms are very important industrially and are used to make many different types of food products. The different metabolic end products produced by each specific bacterial species are responsible for the different tastes and properties of each food. Not all fermentative organisms use substrate-level phosphorylation. Instead, some organisms are able to couple the oxidation of low-energy organic compounds directly to the formation of a proton or sodium motive force and therefore ATP synthesis.
Examples of these unusual forms of fermentation include succinate fermentation by Propionigenium betwedn and oxalate fermentation by Oxalobacter formigenes. These reactions are extremely low-energy yielding.]
