reduction-oxidation (redox) potential (Reed and Green‚ 1998). Succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) are enzymes that play a role in the Citric Acid Cycle portion of cellular respiration and are investigated further in this experiment. The purpose of this experiment was to prepare whole as well as broken preparation of mitochondria and compare the enzymatic activity of succinate dehydrogenase (SDH) and malate dehydrogenase (MDH). This experiment will answer the question of whether enzymatic

electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled. The hydrogens remain in the matrix while the two electrons are

Introduction The energy consumption grows year by year with the economical development of the countries such as China and Japan despite the boisterous events. With the ‘Arab Spring’ in 2011‚ energy market was shook in terms of both production and consumption of the oil with the loss of one of the suppliers‚ also the massive earthquake and tsunami that hit Japan coast caused immediate action for nuclear power and other fuels around the world. Due to those events‚ oil prices reached an all-time record

addiction using aversion therapy. Normally when you ingest alcohol‚ it is first broken down into a toxic chemical called acetaldehyde‚ but is then broken down by the enzyme alcohol dehydrogenase into acetic acid‚ which is harmless. In this treatment a drug is supplied called disulfiram‚ which blocks alcohol dehydrogenase so acetaldehyde builds up. This causes the unpleasant symptoms of dizziness‚ sickness‚ palpitations etc. The aim is to classically condition this sickness with alcohol so the user

(or metabolizing) the alcohol in the body. About 90% of the alcohol leaves the system through the liver (Uppers‚ Downers‚ All Arounders‚ 2011‚ p. 58). An enzyme in the liver metabolizes alcohol first by alcohol dehydrogenase (ADH) into acetaldehyde‚ then by acetaldehyde dehydrogenase (ALDH) into acetic acid‚ and then finally it is oxidized into carbon dioxide. The normal liver can process about a half an ounce of pure alcohol

3 Yeast Metabolism Metabolism refers to the biochemical assimilation (in anabolic pathways) and dissimilation (in catabolic pathways) of nutrients by a cell. Like in other organisms‚ in yeast these processes are mediated by enzymic reactions‚ and regulation of the underlying pathways have been studied in great detail in yeast. Anabolic pathways include reductive processes leading to the production of new cellular material‚ while catabolic pathways are oxidative processes which remove electrons
