Premium Adenosine triphosphate Photosynthesis Cellular respiration
to produce high energy adenosine triphosphate (ATP) molecules. This procedure is carried out by every cell in both plants and animals and is essential for everyday living. There are three main stages to cellular respiration – glycolysis‚ the citric acid cycle and the electron transport chain. Glycolysis means “sugar splitting” and takes place within the cytosol of a cell and can continue in both aerobic and anaerobic conditions. Glycolysis is able to produce energy in the absence of oxygen‚ however

Objectives for Lecture 9 Know the difference in resolution and magnification between light and electron microscopes. Understand the process of cell fractionation based on centrifugation and know what the purpose of cell fractionation is. Know what the differences in cell structure are between prokaryotic cells and eukaryotic cells Know that most eukaryotic cells are between 10-100 m in diameter‚ whereas most prokaryotic cells are about 1 m in diameter. Know the following terms‚ plasma

before the Krebs cycle will take place? 6. What molecule is found at the beginning of acetyl co-A formation? 7. a. How is pyruvic acid changed to acetyl co-A? b. When pyruvic acid is changed to acetyl co-A‚ is it being oxidized or reduced? 8. Summarize all of the important products (and their quantities) yielded after one pyruvic acid molecule “leaves” glycolysis and goes through the acetyl co-A formation stage. 9. What is another name for the Krebs cycle? Citric acid cycle 10. How is the

monoglycerides‚ and triglycerides are all types of lipids. Triglycerides are a main form of energy for both plants and animals. Triglycerides are broken down into 3 fatty acid chains. Each fatty acid chain is further broken down into multiple groups of Acetyl CoA. Acetyl CoA molecules go through the citric acid cycle and the electron transport chain. 12 ATP are formed from each Acetyl CoA molecule. Carbon chains that are saturated with hydrogen atoms Chains are straight and can pack tightly

Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? In glycolysis‚ the 6-carbon sugar‚ glucose‚ is broken down into two molecules of a 3-carbon molecule called pyruvate. This change is accompanied by a net gain of 2 ATP molecules and 2 NADH molecules. Glycolysis occurs in the cytosol (Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of the citric acid cycle

9–2 The Krebs Cycle and Electron Transport (p. 226-232) How much of the energy that is available in glucose‚ has been used/released by the end of glycolysis? Only about 10%. To get the rest of the energy released‚ what powerful electron acceptor does a cell use? oxygen Define aerobic: refers to a process that requires oxygen Look up and define anerobic: refers to a process that is ‘not in air’ or does not require oxygen Cellular respiration specifically refers to

1. Citric Acid * Citric acid is a weak organic acid with the molecular formula C6H8O7‚ which means a molecule of the acid contains six carbon atoms‚ eight hydrogen atoms‚ and seven oxygen atoms. When it is dissolved in water‚ it partially ionizes to yield three H+ ions (hydrogen atoms which are missing their electron) and a C6H5O7(3-) ion (the 3- means that it has three extra electrons.) The resulting solution is called an "electrolyte." Chemical Reaction When two dissimilar metals are put
