Measuring Cellular Respiration And Fermentation

Respiration is a chemical process by which organic compounds release energy. There are two types of respiration reactions that cells use to provide themselves with energy: aerobic and anaerobic (fermentation). (Chemistry for Biologists: Respiration. 2015) Both processes are similar within the initial steps of the reaction- beginning with glycolysis. However, in fermentation instead of the pyruvic acid being converted to acetyl coenzyme A, it’s converted into both ethanol and carbon dioxide in yeast and some plants and lactic acid in animal cells. Another distinct difference between the two processes is that anaerobic respiration uses oxygen

The purpose of the Cellular Respiration lab was to identify if cellular respiration is sped up due to exercise. To conduct the experiment each student filled a beaker with 15 ml of water and three drops of bromothymol blue. Next each student blew into the beaker through a straw until the water mix turns yellow. When carbon dioxide is added too bromothymol blue it changes to a yellow color. Each student times how long it takes for the water to turn yellow, records the data, and then reset the lab. Subsequently the student would exercise for a total of five minutes and then repeating the lab, again recording how long it takes for the water mix to turn yellow.

Cellular respiration occurs when cells release energy from food molecules. Aerobic respiration includes the process of glycolysis. Glycolysis produces ATP by forming glucose into pyruvate. Anaerobic respiration includes the process of fermentation. Fermentation uses the pyruvate made in glycolysis to make ethanol and NAD+. Fermentation may also produce lactic acid and NAD+. The electron transport chain uses electrons from hydrogen to produce ATP. The electrons are carried through the 4 complexes by NADH. Hydrogen ions leave the inner membrane space through the ATP synthase and react with ADP and an inorganic phosphate to produce ATP.

Cellular respiration is a sequence of three metabolic stages. Stage one is glycolysis and occurs in the cytoplasm. Stages two and three occur in the mitochondria and are respectively called the Krebs cycle and the electron transport chain. Both autotrophs and heterotrophs use these metabolic stages to produce the energy required to grow, reproduce and undertake maintenance, in the form of ATP (Flinders University , 2018). A step in the Krebs cycle can see an enzyme catalysed conversion of succinate to fumarate where an electron is transferred from one complex to another, a redox reaction (Knox, et al., n.d.). Substrate concentration is a variable used to increase the rate of a reaction. It is a limiting factor however, up until a certain point,

Cellular respiration is a set of chemical transformations in the cell which convert energy gained from food into ATP and then release waste products. In this process, there are two steps, glycolysis, and the Krebs Cycle. . First, the cells goes through glycolysis. One molecule of glucose is converted into two molecules of pyruvate, four molecules of ATP and two NADH molecules as well as water and heat. Then, the pyruvate is sent to the mitochondria, where it is taken apart to produce an acetyl group which joins the enzyme CoA to form acetyl CoA.

The way in which different organisms acquire oxygen in exchange for carbon dioxide has truly evolved. The exchange of carbon dioxide for oxygen is essential for the survival of organisms that need to produce the energy molecule ATP through the process of cellular respiration. Respiration (breathing) is the way organisms exchange gases with their environment (White and Campo 2004). During cellular respiration organisms break down energy rich macromolecules such as starch to make ATP in a chemical reaction where oxygen and water is involved (Ege R. and A. Krogh 1914).The use of oxygen is very important; therefore the efficient

For cellular respiration the mitochondria were expected to respire, while the inclusion of succinate would be necessary for the oxidation of DPIP (Upadhyaya, 2017). These hypotheses were proven to be correct. In the fermentation lab the metabolic rate was recorded by measuring the amount of CO2 released, which differentiated among the different carbohydrates and temperatures which was attributed to the one being a monosaccharide (glucose), a disaccharide (sucrose), and a polysaccharide in the form saturated starch. The simple sugars had a faster metabolic rate because their bonds were more readily broken down. In the cellular respiration lab it was shown that mitochondria respire regardless of the addition of succinate, however, when succinate is added it would increase the rate of respiration.

Purpose : The purpose of this lab is to understand the metabolic process of the cellular respiration by which it produce and convert energy. Moreover, an overview of the four major processes of the cellular respiration which is glycolysis, pryuvate the citric acid cycle, and the electron transport chain

For cellular respiration to happen, the materials needed are oxygen, glucose(sugar), and it happens in the mitochondria. The symbol formula for glucose is “C6H12O6”. The oxygen comes from the plant, the plant absorbs carbon dioxide and produces oxygen. The glucose comes from photosynthesis, when photosynthesis happens it absorbs glucose and produces it as well. The mitochondria is a cell organelle found in all organisms which converts glucose(sugar) into energy(ATP) for the cell.

All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the

Cellular respiration is a metabolic process that refers to the creation of intracellular energy in which molecules are oxidized and the final electron acceptor is an inorganic molecule. The process of cellular respiration is further divided into two pathways; anaerobic, which proceeds without the presence of oxygen, and aerobic, which requires oxygen, however, before either form of cellular respiration can occur, the catabolic process of glycolysis must occur as the intermediate products of glycolysis are required to start both aerobic or anaerobic respiration. It should be further noted, that the general term of “cellular respiration” usually refers to aerobic respiration. Glycolysis, sometimes referred to as the Embden-Meyerhof pathway,

The aereobic cellular respiration process happens in four steps and they all have an importance and can not be completed with out all of them involved. The important thing is that it cannot happen without the one that happens before it. Glycolysis is the first step in cellular reperation process. This occurs in the areobic and in the anareobicc ells respiration process. During this step it releases a minute amount of energy.Glycolysis is a model or prototype of what is called the universal mettabolic pathway. It happens in several different ways in all organisms, both aerobic and anaerobic. The vast occurrence of glycolysis tells us that it is one of the oldest known metabolic process.Glycolysis contains ten intermediate compounds, and is

    Cellular respiration is the group metabolic reactions that happen in the cell of living organism that creates adenosine triphosphate, ATP, from biochemical energy. The formula for cellular respiration is C6H12O6 +6O26CO2+6H2O+ATP.  This formula means glucose and oxygen are turned into water,carbon dioxide and adenosine triphosphate (ATP) energy through chemical reactions. Cellular respiration occurs in all cells which allows them to grow. Raphanus raphanistrum subsp. Sativus seed, also known as radish seed, undergo cellular respiration because they are not yet able to perform photosynthesis, which is how plants create their energy. Hymenoptera formicidae,commonly known as ants, undergo cellular respiration to produce the energy they need to live.

In the experiment we examined the catabolic processes among cellular respiration and fermentation. Cellular respiration is a process in which stored energy is released as organic molecules are broken down resulting in ATP (Upadhyaya, 2017, 38). Glycolysis is one of the reactions that occur within cellular respiration. They are referred to as anaerobic since they do not often use or need oxygen. The second reaction produced by glycolysis is also broken down by the cells mitochondria and are conjunctive base pyruvic acids (Upadhyaya, 2017, 39).

Cellular respiration, the great giver of energy to cells, takes place in and around the mitochondria. It involves a series of 3 steps which starts with a large molecule and ends in ATP energy. The first step of this process is called glycolysis and this takes place outside the mitochondria. In this step 2 ATPs are used to “phosphorylate” a glucose molecule making Fructose 1, 6-biphosphate, next the new molecule is broken into 2, 3 carbon molecules, and finally rouge phosphorous are added and hydrogens are removed through oxidation creating 4 molecules of ATP and 2 NADH+H+. The 3 carbon sugars become pyruvic acid. (There is a gain of 2 ATP in this step). The second step is the Krebs cycle. In this step the pyruvic acids enters the mitochondria,
