The final electron acceptor is not oxygen but some other INORGANIC molecule, such as nitrate (NO3), sulfate (SO4), nitrite (NO2) or an ORGANIC molecule such as fumurate. Overall, the process of glycolysis results in the incomplete oxidation of glucose to two molecules of pyruvate, the formation of NADH, and the formation of four molecules of ATP

This subject may not be covered in the lectures, but you are responsible for all of the information in these notes because it is important background for topics in this course, suchas muscle cell physiology (Chapter 7). When fats are being used as the primary energy source such as in starvation, fasting or untreated diabetes, an excess amount of acetyl CoA is produced, and is converted into acetone and ketone bodies
http://dictionary.reference.com/browse/metabolism Competition: low
the sum of the physical and chemical processes in an organism by which its material substance is produced, maintained, and destroyed, and by which energy is made available. Birds, for example, have a high metabolic rate, since they are warm-blooded, and their usual method of locomotion, flight, requires large amounts of energy

Repeat this procedure with the other tubes.The size of the gas bubble produced by the yeast can be measuring the amount of liquid remaining in the tube and subtracting it from the total volume of the tube. Yeast cells in water produced little CO2 because they do not have a source of sugar.Aerobic RespirationWe will measure the rate of aerobic cellular respiration in beans by measuring the volume of O2 consumed using the apparatus shown below
http://www.angelo.edu/faculty/cadkins/cellresp.doc Competition: low
First ATP bonds are broken, so that we are left with ADP + Pi, which releases energy; however, most of the energy stays with the broken-off phosphate, which we can then bond to the molecule that needs the energy. If you run a marathon, or jog for that matter, you use the oxygen you inhale to operate in these aerobic metabolic pathways to provide the energy your muscles need to contract
Carbohydrate Catabolism

Explain why 38 ATPs can be produced from the oxidation of one molecule of glucose in a prokaryotic cell whereas only 36 ATPs are produced from the same process in a eukaryotic cell
http://www.trueorigin.org/atp.asp Competition: low
Plants can also produce ATP in this manner in their mitochondria but plants can also produce ATP by using the energy of sunlight in chloroplasts as discussed later. Now that scientists understand how some of these highly organized molecules function and why they are required for life, their origin must be explained

All the energy in the gas tank when you get in your car is not released all at once but rather in small bursts which allow you to control the car's movement
http://www2.estrellamountain.edu/faculty/farabee/biobk/BioBookglossC.html Competition: low
The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP. Water flows across the respiratory surface of the gill in one direction while blood flows in the other direction through the blood vessels on the other side of the surface

During these reactions oxygen is typically consumed, however, the process may be anaerobic (without oxygen) or aerobic (uses oxygen), depending on availability. In cellular respiration, this oxidation process is controlled so that the energy is captured, and used to drive the other processes that go on inside the cell
Anaerobic Respiration
http://www.anaerobicrespiration.net/ Competition: low
Anaerobic digesters can also be used effectively for waste management, as the anaerobic respiration that is induced during the digestion process also reduces the emission of harmful gases into our atmosphere. There are three types of anaerobe: obligate anaerobe, which do not use oxygen for growth and even get harmed by it; aero tolerant organisms which cannot use oxygen for their growth but are able to sustain in its presence; and facultative anaerobes which can grow without the presence of oxygen and also can utilize its presence

As electrons move with hydrogen atoms from glucose to oxygen, the pull of the oxygen makes it seem as though the electrons were "falling." The electrons are not really falling in the sense of an apple dropping from a tree. But what happens when you sprint to catch a bus? Your leg muscles are forced to work without oxygen, because you are spending ATP more quickly than your lungs and bloodstream can deliver oxygen to your muscles

A series of metabolic pathways (the Krebs cycle and others) in the mitochondria result in the further breaking of chemical bonds and the liberation of ATP. Immediately after exposure to 14CO2, the plant's photosynthetic tissue is killed by immersing it in boiling alcohol, and all of the biochemical reactions cease

In some ways similar to the chloroplast, the mitochondria also has two main sites for the reactions: The matrix, a liquidy part of the mitochondrion, and the christae, the folded membranes in the mitochondrion. In our cells, anaerobic respiration results in the production of lactic acid, the molecule that builds up when you 'feel the burn' during or after strenuous exercise
Food energy - Wikipedia, the free encyclopedia
http://en.wikipedia.org/wiki/Food_energy Competition: low
An older metric system unit of energy, still widely used in food-related contexts, is the calorie; more precisely, the "food calorie", "large calorie" or kilocalorie (kcal or Cal), equal to 4.184 kilojoules. Conventional food energy is based on heats of combustion in a bomb calorimeter and corrections that take into consideration the efficiency of digestion and absorption and the production of urea and other substances in the urine

If oxygen is present in the cell, then the cell can subsequently take advantage of aerobic respiration via the TCA cycle to produce much more usable energy in the form of ATP than any anaerobic pathway. For example, when muscle cells are working very hard and exhaust their oxygen supply, they utilize the anaerobic pathway to lactic acid to continue to provide ATP for cell function

Where is ATP synthase located in the mitochondrion? inner membrane It is possible to prepare vesicles from portions of the inner membrane of the mitochondrial components. First, however, the pyruvate 1) loses a carbon, which is given off as a molecule of CO2, 2) is oxidized to form a two-carbon compound called acetate, and 3) is bonded to coenzyme A

Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP.In respiration, glucose is oxidized and thus releases energy. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.To regenerate NAD+ from NADH, the electrons from NADH are added to pyruvate to produce alcohol (plants, yeast) or lactate (animals, bacteria).The total ATP yield of fermentation comes from glycolysis; 2 ATP molecules are produced per glucose
Cell Respiration

Each and every cell in every organism (plant or animal) must have oxygen in order to make ATP so that each cell has the energy available to maintain its complex organization that is essential for that cell to carry out the basic functions required to stay alive. To make the electro leave the atom, you are going to have to add energy to it to make it move away from the positive charges--just like opposite poles of magnets require energy to be pulled apart
Cell Respiration: Introduction

Since most textbooks provide abundant details of the chemical reactions in respiration, this tutorial will focus on how the chemical energy in glucose is converted into ATP and where respiration occurs in the cell. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved
Cellular Respiration

Because there are a number of enzymes and steps involved in forming porphyrin rings, there are a number of possible points in the process where genetic defects could occur. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation (other types of fermentation such as methanol fermentation and acetone fermentation also exist)

Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.
