Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule. This occurs in both eukaryotic cells, as well as, prokaryotic cells. In the prokaryotic cells, it takes place in the cytoplasm; in the eukaryotic cells, it takes place in the mitochondria. Oxygen is vital for ATP production …show more content…

Glucose, which is a six-carbon sugar, is at that moment divided into two molecules of a three carbon sugar. The breaking down of glucose, takes place in the cell’s cytoplasm. Glucose and oxygen are produced from this breakage, and are supplied to cells by the bloodstream. Also produced by glycolysis are, 2 molecules of ATP, 2 high energy electron carrying molecules of NADH, and 2 molecules of pyruvic acid. Glycolysis happens with or without the presence of oxygen. When oxygen is involved, glycolysis is the beginning step of the process known as, aerobic cellular respiration. When oxygen is not involved, cells are only allowed to produce small quantities of ATP, this process is called anaerobic …show more content…

For example, fermentation occurs in yeast in order to gain energy by transforming sugar into alcohol. Fermentation is also used by bacteria, they convert carbohydrates into lactic acid. Ethanol fermentation is done by yeast and certain bacteria, when pyruvate is separated into ethanol and carbon dioxide. Ethanol fermentation has a net chemical equation: C6H12O6 (glucose) > 2C2H5OH (ethanol) + 2CO2 (carbon dioxide). This process of ethanol fermentation is used in the making of wine, bread, and beer. The pyruvate molecules that were created in glycolysis are then sometimes fermented into lactic acid. Lactic acid can be used to transform lactose into lactic acid, for example in the making of yoghurt. This process is also used in animal muscles when they require extra energy in their tissue in order to run faster than oxygen can be given. C6H12O6 (glucose) > 2CH3CHOHCOOHc*lactic acid) is the net equation for glucose to lactic acid. C12H22O11 (lactose) + H2O > 4CH3CHOHCOOH (lactic acid) is the equation for lactose to lactic acid.

    Anaerobic glycolysis is a system that doesn’t require oxygen but uses glucose to form ATP. This pathway occurs within the sarcoplasm through two separated phases: investment and generation. The investment phase give one energy of ATP to glucose to help break it down. The breakdown or net gain of glucose into components of two ATP and two pyruvate is generated in this generation phase. This second system of anaerobic glycolysis is very important for Rupp as his muscles will produce ATP somewhat rapidly during his exercise of running.

    Bacteria requires to adjust to their environment and to consume any metabolic fuels that can be accessible for their survival; the best favored would be glucose. If it happens that there is a lack or deficit of the glucose, bacteria cells must acclimate to utilizing another form of sugar lactose. This can be achieved by changing the absorptions of some proteins. Lac repressor can bind to major groove of lac operon which results in inhibiting the transcription of mRNA for Lac proteins; this is the case when there is no lactose present. When lactose is available the protein allo-lactose goes to bind to lac operon that able it to change in shape of lac repressor, consequently it will not be able to bind to the lac operon, this is called

    Oxidative Phosphorylation is the metabolic pathway in which mitochondria use their structure, enzymes, and energy released by the oxidation of nutrients to create ATP. If cells become oxygen deficient, the condition known as hypoxia (no oxygen) occurs. This condition can be due to abnormally acidic blood or a lack of critical enzymes necessary for releasing oxygen from red blood cells, so when this oxidative cycle is oxygen deficient, it can’t produce the quantity nor quality of ATP necessary for normal cellular functioning. “Oxygen is alkaline forming in the blood, while carbon dioxide which is produced as a by-product of the oxidation process is acid forming.

    The cytosol in a cell does more than just suspend the organelles. It uses its dissolved enzymes in order to break down all of the larger molecules. The products can then be used by the organelles of the cell. Glucose exists in the cytosol but the mitochondria can 't use any of it for fuel. The cytosol has enzymes that break glucose down into pyruvate molecules that are then sent to the

    Glycolysis is oxygen independent, meaning that it does not use oxygen in order to carry out its pathway. The products of glycolysis which are pyruvate and NADH, H+ are sometimes disposed of using atmospheric oxygen. So when they are disposed of using oxygen they are referred to as aerobic, and when they are disposed of without oxygen they are called anaerobic. Glycolysis tends to take place in the cytosol of the cells in majority of organisms. In glycolysis it starts off by having a sugar come by that can be broken down, so the sugar I used in the enzymatic reaction is glucose.

    photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

    Lactose is a disaccharide, a sugar that is formed when glucose and galactose, simpler sugars or monosaccharides undergo a condensation reaction. This disaccharide is found in the milk of mammals and provides a source of energy for infants that rely on their mother’s milk and acts as a substitute to solid foods and provides nutrition. Lactose is digested, absorbed by the small through the help of the enzyme lactase. This is imperative as it cannot be absorbed in its plain form and so must be broken down into simpler sugars. This reaction is called a hydrolysis reaction in which water that is formed as a by-product in a condensation reaction is used to breakdown the covalent bond in the disaccharide, known as the glycosidic linkage, to form two

    The mitochondria are some of the most important organelles within the cell. Not only do the mitochondria help to build components of hormones and blood in the body and contain necessary enzymes in some cell types, but also they provide energy needed for the cell. The mitochondria are particularly known for the process of cellular respiration, or the process in which oxygen and glucose are used to produce carbon dioxide, water, and ATP (adenosine triphosphate). In 2014, an experiment was conducted to observe the salivary glands in laboratory rats at the National Institute of Dental and Craniofacial Research (NIDCR).

    The primary role of mitochondria, in eukaryotic cells, is production of metabolic energy. They play a role in oxidative phosphorylation (final step in aerobic respiration) during which ATP is produced. Energy is produced via oxidation of pyruvate and NADH. Firstly the link reaction takes place in the mitochondrial matrix, during which acetyl CoA is formed. This step is followed by the Krebs Cycle in the same location, resulting in 2 CO2, 1 ATP, 3 NADH+H+ and 1 FADH2 molecules.

    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.
