Cellular Respiration Lab Report
Cellular respiration, the first phase is Glycolysis, a six-carbon sugar being glucose goes through chemical transformations. The result of this is two molecules of pyruvate. Throughout the first phase ATP is made and NAD+ is turned into NADH. Next of is a mini-phase prior to the Kreb Cycle, in this mini-phase pyruvate reacts with coenzyme A, a reaction produces carbon dioxide, NADH, acetyl CoA. The next phase is the Krebs Cycle or the Citric Acid Cycle, Acetyl CoA made in the previous step joins with the four-carbon molecule and goes through a cycle of reactions, this refuels the four-carbon molecule that is the starter. ATP, NADH, and FADH2 are made and carbon dioxide is released. The Electron Transport Chain this is the final phase this produced

965 Words | 4 PagesThe blood cells release oxygen, which passes through the capillary walls into nearby tissue. Tissue then releases carbon dioxide through the capillary walls into the red blood
Mitochondria Lab Report
737 Words | 3 PagesDuring this experiment, mitochondria were isolated from 20.2 grams of cauliflower using extraction buffer, filtration through Miracloth, and centrifusion. Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases. Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present.

1079 Words | 5 PagesCell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
Cellular Respiration Lab
478 Words | 2 PagesCellular Respiration Lab Introduction In this lab, the primary investigation was to discover which factors affect cellular respiration. In this particular inquiry, the factor tested was the amount of time the lentil seeds were germinated. This study was performed in order to understand the process of cellular respiration as well as be able to measure and observe gas concentration as a result of impacting factors. Cellular respiration is necessary for life-processes, converting glucose and oxygen into ATP, carbon dioxide, and water, in a series of metabolic reactions.

1771 Words | 8 Pages● Once oxygen is available, lactic acid is oxidized by NAD+ to recreate pyruvate which can then proceed through pyruvate oxidation to form acetate to enter into Krebs and NADH which can move to the ETC for a series of redox reactions to create ATP through oxidative
Galen Rupp: The Boston Marathon
567 Words | 3 PagesAnaerobic 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.
Fatty Acids In The Kite Runner
1840 Words | 8 PagesA total 8 cycles takes place in the citric acid cycle which begins with acetyl CoA that condenses with oxaloacetate to produce citrate and at the end of the CAC cycle oxaloacetate is generated again for another cycle. In CAC 2 CO2, 1 GTP, 3 NADH and 1 FADH is produced. CAC is highly exergonic with –50.3 KJ/mol. Acetyl CoA condenses with oxaloacetate that produces 2CO2 and oxaloacetate. 3 NAD+ +6e- + 6H+ is used to produce 3 NADH + 3H+.
Metabolic Pathways Lab Report
602 Words | 3 PagesThe four pathways such as glycolysis, pyruvate oxidation, Krebs cycle and electron transport chain are needed in the harvesting of energy from glucose contained in the food that had been ingested. The aerobic pathways of glucose breakdown involve in the complete oxidization to CO2 and H2O. The glycolysis process involved the conversion of the six-carbon glucose molecule to two
Photosynthesis Lab Report
520 Words | 3 PagesAlso cellular respiration is an aerobic reaction meaning it require oxygen to take place and releases a CO2 by product. In the experiment aged water was used as the control. The CO2 and O2 levels were tested and used as the base level coming in at 7.6ppm for O2 in Table 1 and 12.3 ppm for CO2 in Table 2. Three variables were set up with controls.
Cellular Respiration Research Paper
1393 Words | 6 PagesWhen 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
Compare And Contrast Cellular Respiration And Photosynthesis
420 Words | 2 PagesThe 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.
Cellular Respiration Lab Report
299 Words | 2 PagesCellular respiration is the process in which molecules are broken down to release stored energy. The energy (ATP) is used as power for the cell, completing chemical tasks (Upadhyaya, 2017). Cellular respiration must always be taking place for cell survival. There are two phases of cellular respiration, the first phase is anaerobic while the second is aerobic. Cellular respiration takes place in the human body during everyday activities such as biking, running, and weightlifting.

1250 Words | 5 PagesAdditionally, the stored oxygen supply is reduced, and the anaerobic metabolism starts to maintain the homeostasis. This process needs energy from ATP. All of those start the major energy reserve through glycogen catabolism because the reaction using creatine phosphate in postmortem muscle lasts shortly. Glycogen must first be degraded by glycogen phosphorylase to form glucose-1 phosphate. The whole process produces three ATP with glycogen as starting material.
Cellular Respiration In Yeast Lab Report
780 Words | 4 PagesThe Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Lab Report On Fermentation
1432 Words | 6 PagesThen, 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.
