The remain three-carbon compounds are converted back into five carbon molecules (RuBP) through the addition of phosphates from ATP 14Harvesting Chemical EnergyPlants and animals both use products of photosynthesis (glucose) for metabolic fuel Heterotrophs must take in energy from outside sources, cannot make their own e.g. Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles
How it works - Respiration - Forms of Respiration, How Gases Move Through the Body
This compound is carried by the bloodstream back to the gills or lungs, and, at the end of the journey, it breaks down and releases the carbon dioxide to the surrounding environment. Birds have specialized lungs that use a mechanism called crosscurrent exchange, which allows air to flow in one direction only, making for more efficient oxygen exchange
Breaking Down Fat and Losing Weight - HowStuffWorks
Once in the liver, the glycerol and fatty acids can be either further broken down or used to make glucose.Losing Weight and Losing FatYour weight is determined by the rate at which you store energy from the food that you eat, and the rate at which you use that energy. However, your body is always using energy; and if you're not absorbing food, this energy must come from internal stores of complex carbohydrates, fats and proteins
Cellular Respiration -- Exploring Nature Educational Resource
What happens if there is no oxygen where an organism lives (anaerobic conditions)? In that case, the organism can still create energy, but through the process of fermentation. Yeast can also release carbon dioxide in this process, which is what causes bread to rise.In animals, the lack of oxygen will drive muscle cells to carry on lactate fermentation which creates lactic acid causing sore and cramping muscles
Cellular Respiration
Remember that for each molecule of glucose, two Acetyl Co-A molecules are produced; therefore the KCAC occurs twice for each glucose, so all products here are X 2.
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

You know that shirt you're wearing? If it is made of cotton, that's cellulose, too! There can be thousands of glucose subunits in one large molecule of cellulose
Enzymes - How Cells Work
Breaking molecules apart and putting molecules together is what enzymes do, and there is a specific enzyme for each chemical reaction needed to make the cell work properly. The active site on the enzyme breaks the bond, and then the two glucose molecules float away.You may have heard of people who are lactose intolerant, or you may suffer from this problem yourself
While the molecules are being rearranged in this cycle, carbon dioxide is produced, and electrons are pulled off and passed into an electron transport system which, just as in photosynthesis, generates a lot of ATP for the plant to use for growth and reproduction. They conserve water a lot better than we do.Can plants live without animals? Can animals live without plants?Thanks for asking.Click Here to return to the search form
Where Does Plant Respiration Take Place? Does Cell Respiration Only Take Place in Plant Cells? Cellular respiration is a metabolic process essential to the functioning of all cells. The cell makes a tiny amount of ATP during glycosis, but the primary reason for this step is the creation of intermediary chemical substances from glucose
These cellular structures primarily function for the breakdown of complex molecular substances, such as carbohydrates, lipids, proteins and nucleic acids. These components can be utilized to give energy when it is needed and are an important part of powering metabolic processes and constructing new cellular components
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
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
Electron Transport Chain and Oxidative Phosphorylation In the electron transport chain, which in animal cells is located mostly on the inner membranes of mitochondria, reduced products such as NADH and FADH2 are used to create a proton gradient -- an imbalance in the concentration of unpaired hydrogen atoms on one side of the membrane vs. Cellular respiration, on the other hand, involves taking electrons away from a substrate (glucose, for instance), which is to say oxidation, and in the process the substrate is degraded so that its carbon atoms are released as CO2, while oxygen is consumed
Cellular Respiration:
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
Cellular Respiration
This has strengthened the theory that mitochondria are the evolutionary descendants of a bacterium that established an endosymbiotic relationship with the ancestors of eukaryotic cells early in the history of life on earth. (Defects in either process can produce serious, even fatal, illness.) The Outer Membrane The outer membrane contains many complexes of integral membrane proteins that form channels through which a variety of molecules and ions move in and out of the mitochondrion
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)
How does an animal cell react when there is no glucose available to carry out cellular respiration
Today, cell biology still drives unique and fundamental discussion as to how life works and how organisms function.Once known as cytology, cell biology is a subdivision of biology that focuses on the structure and function of cells.
