Respiration

The rate of respiration of yeast, using two saccharides and an amino acid, in combination with the cofactor of magnesium, was determined using respirometers. A positive control sample of yeast and water, and a negative control sample of glucose, sodium fluoride and yeast were also employed. After seventy five minutes, the sample containing glucose, magnesium and yeast showed a markedly higher production of CO2 than the other samples. This result supported the hypothesis that glucose is the…

cellular respiration based on the available fuel source in the different seeds. We know that aerobic respiration requires oxygen gas and an organic molecule, and produces carbon dioxide, water, and energy. The goal of cellular respiration is to harvest ATP. However, the carbon dioxide can be measured using a gas sensor. Since we know that more reactants generally equals more products, more organic molecules should result in more carbon dioxide, thus, increasing the rate of cellular respiration.…

the ability to do work, hence, for metabolic reactions to occur a supply of energy is needed. The law of conservation of energy states that energy can neither be created nor destroyed, but transfers from one state to another. Photosynthesis and Respiration, are two processes involved in the production of energy. These processes will now be examined. Photosynthesis is the process of converting light energy from the sun to chemical energy and storing it in the bonds of sugar. The only organisms…

process can be carried out; anaerobic or aerobic. Plants normally aerobically respite but in case of little to no exposure to air, anaerobic respiration is done. The process of cellular respiration takes place in the mitochondria of cells. All functions and structures in plants have been adapted to optimise the processes of photosynthesis and respiration. Plants have a root system, a stem, branches and leaves. The roots primary job is to absorb water and the nutrients from the soil. This is…

The Effect of Cellular Respiration at Low and High Temperatures Introduction Cellular respiration can include two processes, aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to breakdown sugars into smaller structures so that the cell can use it as energy (Reece, et al. 2014). The main concept of the respiration lab is aerobic respiration. This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and…

Introduction: Cellular Respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. This occurs in three phases: glycolysis, the Kreb’s cycle and oxidative phosphorylation. When measuring consumption of oxygen during the oxidation of glucose, respirometers are used. Respirometers are devices that measure these types of gas volume changes, and…

INTRODUCTION Cellular respiration is the breaking down of organic molecules by means of catabolic pathways that uses electron transport chain to produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction. Cellular respiration is the…

The process of Cellular Respiration occurs in every living thing on the planet. This process creates energy and we all need energy to survive. The three stages of Cellular respiration are Glycolysis, The Kreb’s Cycle and The Electron Transport chain. Glycolysis is the first step to cellular respiration. There are 2 stages that make Glycolysis happen. The first is the “Investment” stage. As you consume food, glucose is consumed and passed through the cytoplasm. In order for the investment stage…

Hypothesis: Aerobic Respiration: If a phosphate buffer, dichlorophenol-indophenol and succinate are added to a mitochondrial extract then the succinate molecules will bind to an enzyme complex (succinate dehydrogenase). Because the enzyme and FAD are a part of the same complex, initiating succinate oxidation, this reaction reduces FAD to FADH2. Thus the oxidation of succinate to furmarate. Anaerobic Respiration: If a solution of yeast and glucose is combined and placed in different incubation…

Exercise's Effects on Cellular Respiration Cellular respiration is a chemical reaction that creates energy through your cells. It requires inhaled oxygen and expels carbon dioxide. This carbon dioxide can be detected through the use of bromothymol blue (BTB), which is a pH indicator solution. When the carbon dioxide is exhaled into the solution, BTB reacts as it would with any other acid, and turns from blue to yellow. The higher the level of carbon dioxide, the more quickly the color changes…
