Fermentation is breaking down glucose without any oxygen. But there is a more detailed and complete way of breaking down glucose and that is called cellular respiration. Aerobic respiration is when oxygen is used as the reactant, but an organic fuel is also used. Cellular respiration can have not anaerobic and aerobic processes. When one substance moves electrons completely to a whole different electron is called a redox reaction. When electrons are lost from one substance it is known as oxidation. However, reduction is when electrons are added to a substance. When aerobic respiration happens electrons are moved to NADH before anything else which reduces it, and eventually goes into and forms the Electron Transport Chain. After all this takes …show more content…

Acetyl CoA has a way of feeding itd group in the citric acid cycle and then it is able to go through oxidation. Cytochromes are proteins that is mainly left over between ubiquinone and oxygen. A lot of what is in the inner membrane of the mitochondria are a lot of copies of a protein known as ATP Synthase. This is what usually will make ATP to ADP, and is a enzyme. A process where energy is stored as a hydrogen ion across a membrane that helps with cellular work is known as Chemiosmosis. There are two known forms of fermentation and they are alcohol fermentation and lactic acid fermentation. When alcohol fermentation happens pyruvate is changed into ethanol by a two step process. When lactic acid fermentation happens pyruvate is being reduced by NADH which forms lactate as the end product and does not release any CO2. there are organisms that are called Obligate Anaerobes and they are only able to do fermentation or anaerobic respiration. Also, they do not live with oxygen. Other organisms are known as Facultative anaerobes that are able to make ATP to help them survive by using respiration or

  Sucrose fermentation: This fermentation makes energy available for use by microorganisms by anaerobic breakdown of carbohydrates. It can either be an acid or gas. When positive turns red to yellow and can have gas present which form bubbles.   H2S production: H2S is a toxic gas produced by the decomposition of sulfur-containing amino acids cysteine and methionine or the reduction of inorganic sulfur compounds by enzymes of certain bacteria. If hydrogen sulfide is formed, it reacts with ferrous salts to form black metal sulfides that can be visualized

Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.”

The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.

This laboratory experiment was performed to study mitochondrial function by observing the effects that substrates and inhibitors have on the processes of the electron transport chain. The electron transport chain is a series of complexes (I-IV) that use oxidation and reduction reactions to transfer electrons from donors to acceptors. These oxidation and reduction reactions couple the electron transfer with the transfer of protons (H+ ions) across the membrane. Complexes I, III, and IV are involved in pumping H+ ions into the inter-membrane space as electrons pass through them. The Citric Acid cycle is responsible in producing electrons which are transported to the Electron Transport Chain using NADH+ and FADH2 as carriers.

Sugar/ glucose is an important carbohydrate that can be made during photosynthesis from water and carbon dioxide, using energy from sunlight. Carbon dioxide is given off as a waste product when energy is released by the breaking down of glucose. This can be used by plant cells in the process of photosynthesis to form new carbohydrates. Yeast is a single-celled fungus that can break down sugars (glucose) to help produce carbon dioxide. Research Question

I figured that since glucose was already simplified, it would be the best for cellular respiration. But actually sucrose, a disaccharide, is the best. CO2 is used to measure cellular respiration, because cellular respiration takes in oxygen and lets out carbon dioxide. Sugar and oxygen give out water,carbon

Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks. The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.

In respiration, enzymes contain an important role where aerobic respiration exhales the energy that is in glucose. In order for aerobic respiration to work it needs oxygen, and in this process, the energy that is released is utilized in the making of smaller molecules and the maintenance of a constant body temperature (BBC News, 2015). Enzymes are likewise proteins that are collapsed into complex shapes that

This happens because enzymes lower the activation energy, as they provide an alternative reaction pathway. The decrease in the energy level aids in making the process happen faster (Jae In Lee, 2011) A catalase is an enzyme, which is found in all living organisms. This enzyme helps to convert hydrogen peroxide into oxygen and water. Chemical actions that happen within the cell produces hydrogen peroxide, which is poisonous and therefore can kill the organism.

Role of Enzymes in Metabolic Pathways Summary Metabolic pathways are a sequences of steps found in biochemical reactions in which the product of one reaction is the substrate for the next reaction [3]. Metabolic pathways most likely happen in specific locations in the cell. The control of any metabolic process depends on control of the enzymes responsible for the reactions occur in the pathways. After food is added to the body, molecules in the digestive system called enzymes break proteins down into fats into fatty acids, amino acids, and carbohydrates into simple sugars (for example, glucose). Enzymes plays an important role in the different metabolic pathways [5].

They can also act as a final electron acceptor. Many bacteria can be differentiated and are identified by their capacity to reduce nitrates to nitrites. Most of the bacteria belonging to the family Enterobacteriaceae reduce nitrates [165]. OF test is used to differentiate those organisms that utilize carbohydrates aerobically (Oxidation) such as P. aeruginosa, from those that utilize carbohydrates anaerobically (Fermentation) such as members of the Enterobacteriaaceae. The OF medium contains peptone, test carbohydrate and bromothymol blue as indicator.
