- The negative or positive charges on colloid particles make them able to hold cations or anions, respectively, to their surfaces. The charges result from four sources. The net result is oxygen atoms with net negative charge and the ability to attract cations. Edge-of-clay oxygen atoms are not in balance ionically as the tetrahedral and octahedral structures are incomplete.Link: https://support.prodigylearning.com/hc/en-gb/articles/360009329998-Exams-From-Home-EFH-Admin-Guide-Part-3-Delivering-your-Exams-and-Troubleshooting
- When the hydrogens of the clay hydroxyls are ionised into solution, they leave the oxygen with a negative charge anionic clays. This is called law of mass action. This is largely what occurs with the addition of cationic fertilisers potash , lime. A low pH may cause the hydrogen of hydroxyl groups to be pulled into solution, leaving charged sites on the colloid available to be occupied by other cations. This ionisation of hydroxy groups on the surface of soil colloids creates what is described as pH-dependent surface charges.Link: https://ckphu.com/blog/
- Hydrogen ions have a single charge and one-thousandth of a gram of hydrogen ions per grams dry soil gives a measure of one milliequivalent of hydrogen ion. Most of the soil's CEC occurs on clay and humus colloids, and the lack of those in hot, humid, wet climates, due to leaching and decomposition, respectively, explains the apparent sterility of tropical soils.Link: https://osti.gov/etdeweb/servlets/purl/151533
- Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy. In studying energy, the term system refers to the matter and environment involved in energy transfers. Review Questions Which of the following is not an example of an energy transformation? Heating up dinner in a microwave B. Solar panels at work C. Formation of static electricity D. None of the above D Which of the following is not true about enzymes? They are consumed by the reactions they catalyze. They are usually made of amino acids. They lower the activation energy of chemical reactions. Each one is specific to the particular substrate s to which it binds. Give evidence for your answer. Physical exercise involves both anabolic and catabolic processes.Link: https://upsc.gov.in/sites/default/files/GAT%20%281%29.pdf
- Body cells break down sugars to provide ATP to do the work necessary for exercise, such as muscle contractions. This is catabolism. Muscle cells also must repair muscle tissue damaged by exercise by building new muscle. This is anabolism. Explain in your own terms the difference between a spontaneous reaction and one that occurs instantaneously, and what causes this difference.Link: https://justanswer.com/ob-gyn/40vfg-asymptomatic-during-routine-pap-exam.html
- However, a spontaneous reaction need not occur quickly or suddenly like an instantaneous reaction. It may occur over long periods of time due to a large energy of activation, which prevents the reaction from occurring quickly. With regard to enzymes, why are vitamins and minerals necessary for good health? Give examples. Most vitamins and minerals act as cofactors and coenzymes for enzyme action. Many enzymes require the binding of certain cofactors or coenzymes to be able to catalyze their reactions. Since enzymes catalyze many important reactions, it is critical to obtain sufficient vitamins and minerals from diet and supplements. Vitamin C ascorbic acid is a coenzyme necessary for the action of enzymes that build collagen. It allows cells to store energy briefly and transport it within itself to support endergonic chemical reactions. Glycolysis is the first pathway used in the breakdown of glucose to extract energy.

Cell Biology. Chapter Topic 2. Molecular Biology. Energy Flow in an Ecosystem. It is concerned with the life processes, signalling pathways, physiological properties, metabolic properties, chemical properties, and the interaction of cells with their surroundings. Chloroplasts have the remarkable ability to turn light energy into cellular fuel, and use this energy to take carbon dioxide from the air and turn it into sugars that can be used by living things as fuel or building material. Prokaryotic cell is that without a delimited nucleus. Eukaryotic cells are those with nucleus delimited by membrane.

- Mitchell hypotheses, a chemiosmotic model of energy transduction. Bioenergetically, the following overall exergonic reaction occurs: If 2 pyruvate molecules are obtained from the dissimilation of 1 glucose molecule, then 30 ATP molecules are generated in total. Figure shows the enzymatic reactions in the Krebs cycle. The potential energy inherent in these reduced compounds is not available as ATP until the final step of respiration electron transport and oxidative phosphorylation occurs. Figure Krebs cycle also tricarboxylic acid or citric acid cycle. The Krebs cycle is therefore another preparatory stage in the respiratory process. Glyoxylate Cycle In general, the Krebs cycle functions similarly in bacteria and eukaryotic systems, but major differences are found among bacteria.Link: https://minneapolis.craigslist.org/hnp/ctd/d/eden-prairie-2018-mercedes-benz-glc-300/7302688538.html
- One difference is that in obligate aerobes, L-malate may be oxidized directly by molecular O2 via an electron transport chain. A modification of the Krebs cycle, commonly called the glyoxylate cycle, or shunt Fig. This shunt functions similarly to the Krebs cycle but lacks many of the Krebs cycle enzyme reactions. Pyruvate oxidation is not directly involved in the glyoxylate shunt, yet this shunt yields sufficient succinate and malate, which are required for energy production Fig. The glyoxylate cycle also generates other precursor compounds needed for biosynthesis Fig. The glyoxylate cycle was discovered as an unusual metabolic pathway during an attempt to learn how lipid or acetate oxidation in bacteria and plant seeds could lead to the direct biosynthesis of carbohydrates. The glyoxylate cycle converts oxaloacetate either to pyruvate and CO2 catalyzed by pyruvate carboxylase or to phosphoenolpyruvate and CO2 catalyzed by the inosine triphosphate [ITP]-dependent phosphoenolpyruvate carboxylase kinase.Link: http://userfocus.co.uk/articles/cif.html
- Either triose compound can then be converted to glucose by reversal of the glycolytic pathway. The glyoxylate cycle is found in many bacteria, including Azotobacter vinelandii and particularly in organisms that grow well in media in which acetate and other Krebs cycle dicarboxylic acid intermediates are the sole carbon growth source. One primary function of the glyoxylate cycle is to replenish the tricarboxylic and dicarboxylic acid intermediates that are normally provided by the Krebs cycle. A pathway whose primary purpose is to replenish such intermediate compounds is called anaplerotic. Glyoxylate shunt. Electron Transport and Oxidative Phosphorylation The final stage of respiration occurs through a series of oxidation-reduction electron transfer reactions that yield the energy to drive oxidative phosphorylation; this in turn produces ATP. The enzymes involved in electron transport and oxidative phosphorylation reside on the bacterial inner cytoplasmic membrane.Link: https://coursehero.com/file/p4ahh8u0/Global-shift-in-manufacturing-industry-61-62-63-64-65-Lets-explore-Summary-quiz/
- This membrane is invaginated to form structures called respiratory vesicles, lamellar vesicles, or mesosomes, which function as the bacterial equivalent of the eukaryotic mitochondrial membrane. Respiratory electron transport chains vary greatly among bacteria, and in some organisms are absent. The respiratory electron carriers in bacterial electron transport systems are more varied than in eukaryotes, and the chain is usually branched at the site s reacting with molecular O2. Some electron carriers, such as nonheme iron centers and ubiquinone coenzyme Q , are common to both the bacterial and mammalian respiratory electron transport chains.Link: https://dsdweb.co.uk/level-3-diploma-in-care/
- In some bacteria, the naphthoquinones or vitamin K may be found with ubiquinone. In still other bacteria, vitamin K serves in the absence of ubiquinone. Bacteria also possess mixed-function oxidases such as cytochromes P and P and cytochromes c' and c'c', which also react with carbon monoxide. These diverse types of oxygen-reactive cytochromes undoubtedly have evolutionary significance. Bacteria were present before O2 was formed; when O2 became available as a metabolite, bacteria evolved to use it in different ways; this probably accounts for the diversity in bacterial oxygen-reactive hemoproteins. Cytochrome oxidases in many pathogenic bacteria are studied by the bacterial oxidase reaction, which subdivides Gram-negative organisms into two major groups, oxidase positive and oxidase negative. The cytochrome oxidase responsible for the indophenol oxidase reaction complex was isolated from membranes of Azotobacter vinelandii, a bacterium with the highest respiratory rate of any known cell.Link: http://kkl.soundllp.com/hm-king-leung/
- The cytochrome oxidase was found to be an integrated cytochrome c4:o complex, which was shown to be present in Bacillus species. These Bacillus strains are also highly oxidase positive, and most are found in morphologic group II. Energy generated from such membrane oxidations is conserved within the membrane and then transferred in a coupled manner to drive the formation of ATP. The electron transfer sequence is accomplished entirely by membrane-bound enzyme systems.Link: https://quantsoftware.gatech.edu/MC1-Project-1-legacy
