Cellular Respiration?

This brings back dreadful memories! Glucose is the principal sugar in the biological world. Breakdown of glucose happens in two stages. The first stage is glycolosis, which consists of 10 successive steps in which the glucose, a 6-carbon molecule, is converted into two 3-carbon molecules (pyruvate) and two ATP molecules are synthesized from two ADP molecules and two P i. The second stage of glucose breakdown is called celular respiration, converts the pyruvate molecules into CO2 and H2O through 15 steps, some of which are coupled to the synthesis of many molecules of ATP from ADP +Pi. When pure glucose is ignited and burned, it is completely converted to CO2 and H2O with the release of heat. C6 H12 6O2---->6CO2 + 6H20. The breakdown of glucose in a cell leads to the same result. Six O2 molecules are needed to catabolize each molecule of glucose, and 6 molecules of CO2 and 6 molecules of H2O are the end products. For one mole (180 grams) 686 kilocalories are released. In a cell, the breakdown occurs stepwise, with some energy released at each step. By coupling certain of the steps to synthesis of ATP from ADP, energy is captured. Glycolysis carries the breakdown to pyruvate, during which some energy is transferred into a net gain of two ATP molecules. Glycolysis, however, taps very little of the free energy in glucose; about 93% of this energy is still present in the two pyruvate molecules left after glycolysis. This energy is released in stepwise fashion by conversion of pyruvate to CO2 and H2O in cellular respiration, with the generation of 36 ATP molecules. Cellular respiration occurs in two stages. In the first stage, the pyruvate is oxidized in a sequence of reactions to CO2 and H2O, and electrons are transferred to coenzymes. In the second stage, the passage of the electrons along an electron transport chain is coupled to the synthesis of ATP from ADP and Pi in a manner similar to the transfer of electrons and generation of ATP that occurs in phase 1 reactions of photosynthesis. Then you go on to the citric acid or Krebs cycle. I hope this helps. I remember drawing it out over and over to memorize it. The main thing is to remember as the process goes on what the byproducts are-ATP, etc.

Without oxygen your cells would die.  The reason being oxygen is crucial to cellular respiration.  The classic metaphor is to compare cell respiration to a burning trash fire.  If you throw a blanket over the burning pile of trash you smother it (block the oxygen) and the fire goes out.  Without red bloods to carry oxygen to the cells the cellular fires would go out.   If you want to know more about cellular respiration, the Krebs Cycle, ATP and all that good stuff I suggest you start with the reference given below.  Meanwhile keep on asking questions.

respiration..\n\nco2 is given off, it goes through our blood stream, reabsorbed by the alveoli, switched out with o2 by respiration

fermentation:2 ATP\n respiration:36-38 ATP

If you mean cellular respiration, then it would be about 70%.  The majority of the rest is used for neuronal transmission-specifically for maintanence of the ionic gradient.  If you are speaking of merely gross respiration (the movement of air in and out of your lungs) then it would be a very small percentage.

All living organisms require energy to function. This energy may be obtained from the consumed foods. The most efficient way for cells to harvest energy stored in food is through cellular respiration, a catabolic pathway for the production of adenosine triphosphate, or ATP. ATP is a high-energy molecule and it is expended by working cells. The starting material of cellular respiration is the sugar glucose, which has energy stored in its chemical bonds. \n\nThere are actually two general types of respiration, aerobic and anaerobic. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration does not use oxygen. Both types of cell respiration begin with the process of glycolysis, after which the two diverge. \n\n\nAerobic respiration is more efficient and more complicated than anaerobic respiration. Aerobic respiration uses oxygen and glucose to produce carbon dioxide, water, and ATP. More precisely, this process involves six oxygen molecules for every sugar molecule:\n6O2 + C6H12O6 6CO2 + 6H2O + ATP (energy)\n\nAerobic respiration requires oxygen. However, some organisms live in places where oxygen is not always present. Similarly, under extreme exertion, muscle cells may run out of oxygen. Anaerobic respiration is a form of respiration that can function without oxygen.\n\nIn the absence of O2, organisms continue to carry out glycolysis, since glycolysis does not use oxygen in its chemical process. But glycolysis does require NAD+. In aerobic respiration, the electron transport chain turns NADH back to NAD+ with the aid of oxygen, thereby averting any NAD+ shortage and allowing glycolysis to take place. In anaerobic respiration, cells must find another way to turn NADH back to NAD+. \n\nThis “other way” is called fermentation. Fermentation’s goal is not to produce additional energy, but merely to replenish NAD+ supplies so that glycolysis can continue churning out its slow but steady stream of ATP. Because pyruvates are not needed in anaerobic respiration, fermentation uses them to help regenerate NAD+. While employing the pyruvates in this way does allow glycolysis to continue, it also results in the loss of the considerable energy contained in the pyruvate sugars. \n\nThere are two principle forms of fermentation: lactic acid fermentation and alcoholic fermentation. \n\nIn lactic acid fermentation, pyruvate is converted to a three-carbon compound called lactic acid: \npyruvate + NADH lactic acid + NAD+\n\nIn this reaction, the hydrogen from the NADH molecule is transferred to the pyruvate molecule. \n\nLactic acid fermentation is common in fungi and bacteria. Lactic acid fermentation also takes place in human muscle cells when strenuous exercise causes temporary oxygen shortages. Since lactic acid is a toxic substance, its buildup in the muscles produces fatigue and soreness. \n\nAnother route to NAD+ produces alcohol (ethanol) as a by-product:\n\npyruvate + NADH ethyl alcohol + NAD+ + CO2\n\nAlcoholic fermentation is the source of ethyl alcohol present in wines and liquors. It also accounts for the bubbles in bread. When yeast in bread dough runs out of oxygen, it goes through alcoholic fermentation, producing carbon dioxide. These carbon dioxide bubbles create spaces in the dough and cause it to rise. \n\nLike lactic acid, the ethanol produced by alcoholic fermentation is toxic. When ethanol levels rise to about 12 percent, the yeast dies.

Anaerobic respiration occurs without oxygen.  In yeast, it produces carbon dioxide and alcohol, in humans, it produces lactic acid and carbon dioxide.

Cellular respiration is the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes. Oxidation of organic material—in a bonfire, for example—is an exothermic reaction that releases a large amount of energy rather quickly. The equation for the oxidation of glucose is:\n\nC6H12O6 + 6O2 → 6CO2 + 6H2O + Energy released (2830 kJ/mole) \nIn a fire there is a massive uncontrolled release of energy as light and heat. Cellular respiration is the same process but it occurs in gradual steps that result in the conversion of the energy stored in glucose to usable chemical energy in the form of ATP.

the answer is CARBON DIOXIDE

According to the lab experiment we performed, carbon dioxide had to be introduced in a solution to make it more acidic and then the plant was submerged and placed under a light source to act as photosynthesis process. This process takes quite a while, however cellular respiration was already taking place. So I'm thinking the answer is no.

Oh Biology, how do I miss thee!!!!!  Ah that was some good times.  Cytochrome c oxidase is part of the respiration cycle and it accepts electrons.  That about all I can remember but thanks for the points and a trip down memory lane.

ATP maybe.\nGlucose if not.
