Cellular Respiration Lab Report

Cellular Respiration is the physiological process of converting molecules into ATP. This process can occur in bacteria, protists, fungi, plants, and animals. It uses Oxygen (02) and Glucose (C6H1206) to transfer and transform electrons. Then it produces carbon dioxide (CO2) and Water (H2O). Thus, it is read as C6H12O6 + 6O2 --> 6H2O + 6CO2 + 32ATP. Respiration is split into three steps Glycolysis, Citric Acid Cycle, and Electron Transfer Chain (ETC).

In contrast, there are four metabolic stages happened in cellular respiration, which are the glycolysis, the citric acid cycle, and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm, in which catabolism is begun by breaking down glucose into two molecules of pyruvate. Two molecules of ATP are produced too. Some of they either enter the citric acid cycle (Krebs cycle) or the electron transport chain, or go into lactic acid cycle if there is not enough oxygen, which produces lactic acid. The citric acid cycle occurs in the mitochondrial matrix, which completes the breakdown of glucose by oxidizing a derivative of pyruvate into carbon dioxide. The citric acid cycle produced some more ATPs and other molecules called NADPH and FADPH. After this, electrons are passed to the electron transport chain through

This process does not require oxygen and is referred to as fermentation. This process partially breaks down carbohydrates and it obtains a small amount of energy, again in the form of ATP. Pyruvic acid has to be broken down in respiration when formed by breaking down of glucose molecules, this can't be done in the same way as in aerobic respiration. When anaerobic respiration is taking place carbon dioxide and ethanol is formed.

There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration occurs when there is oxygen present and in the mitochondria (in eukaryotic cells) and the cytoplasm (in prokaryotic cells). Aerobic respiration requires oxygen; it proceeds through the Krebs cycle. The Krebs cycle is a cycle of producing carbon dioxide and water as waste products, and converting ADP to thirty-four ATPs. Anaerobic respiration is known as a process called fermentation. It occurs in the cytoplasm and molecules do not enter the mitochondria for further breakdown. This process helps to produce alcohol in yeast and plants, and lactate in animals. Only two ATPs are produced through this process. In yeast fermentation is used to make beer, wine, and whiskey.

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

No, glycolysis does not require the presence of oxygen. It occurs in the cytoplasm of all cells. a single glucose molecule in glycolysis produces a total of 2 molecules of pyruvic acid, 2 molecules of ATP, 2 molecules of NADH and 2 molecules of water.  More ATP molecules are generated in step 7 and 2 more in step 10. This gives a total of 4 ATP molecules produced total with a final total of 2 ATP molecules remaining.

In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP.

Anaerobic respiration occurs when there is no oxygen present in the cycle. Organisms that use anaerobic respiration are mostly prokaryotic organisms. Organisms with habits where there no oxygen is presented such as the deeper part of the ocean

Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a

The first part of cellular respiration is glycolysis where energy is spent to break a glucose molecule down into two pyruvate molecules. A glucose molecule comes from your food and has 6 carbons on it. Glycolysis partially breaks

Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy. Alcohol or lactic acid or other compounds are produced as waste products depending on the kind of cells that are active Use images to provide 2 different examples of

All cells in the human body require sufficient amount of energy in order to sustain life. Cells get their energy through a process called cellular respiration. In this process cells use glucose in the presence of oxygen as a fuel source to synthesize highly energetic molecules of adenosine triphosphate (ATP). ATP is immediately consumed after its formation, so the process of cellular respiration is constantly ongoing. The starting components, glucose and oxygen are converted into carbon dioxide, water and energy. The process of cellular respiration can be divided into three stages: glycolysis, Krebs cycle (citric acid cycle), and the electron transport chain. At the end of the process a total of 38 ATP molecules are produced. In this experiment,

When cellular respiration is in process, hydrogen atoms are removed from glucose and transferred to oxygen atoms that form CO2 and H2O. A major process of cellular respiration is Glycolysis, which occurs in the cytoplasm just outside of the mitochondria. Glycolysis is the process by which glucose is broken down into two pyruvate molecules. Energy is used to release glucose, which gains 2 ATP. Oxidation follows which produces NADH. . (Mader, 2009)

Uniquely, glycolysis is both anaerobic and aerobic. The end product pyruvate, from glycolysis, is anabolized to lactic acid when there is a need for energy without an adequate supply of oxygen available. This last step or reaction enables glycolysis to continue producing ATP without the need for oxygen, which is why it is called the anaerobic energy system (Fink, 2009).

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
