Cellular Energy ReviewRespiration, comparing photosynthesis and respirationMultiple Choice: circle the correct answer.Which types of organisms carry out respiration (aerobic or anaerobic)?Plants AnimalsYeastCertain BacteriaALL Cells_______________________ is the first step in cellular respiration that begins releasing energy stored in glucose.A. Alcoholic fermentationB. Lactic acid fermentationC. GlycolysisD. Electron transport chainIf oxygen is NOT present, glycolysis is followed by _____________________A. Krebs cycleB. Electron transport chainC. FermentationName the 3-carbon molecule produced when glucose is broken in half during glycolysis.A. pyruvic acidB. lactic acidC. Acetyl-CoAD. citric acidSince fermentation does not require oxygen it is said to be __________________.aerobicanaerobicWhich of the following shows the correct sequence during cellular respiration?Electron transport chain → glycolysis → Krebs cycleGlycolysis → Electron transport chain → Krebs cycleKrebs cycle → Electron transport chain → glycolysisGlycolysis → Krebs cycle → Electron transport chain Where do the carbon atoms in pyruvic acid end up after cellular respiration?They carry energy to the many chemical reactions of the cell.They become part of a carbon dioxide molecule and end up in the atmosphereThey recombine to produce sugarsThey build up inside the mitochondriaBecause cellular respiration requires oxygen it is said to be _________________aerobicanaerobic In which organelle does cellular respiration occur?CytoplasmChloroplastC.

How are photosynthesis and aerobic respiration related to one another?The products of one are the reactants of the other.How much ATP is produced byFermentation _____2_______Aerobic Respiration _36-38___________Why do most complex organisms carry out cellular respiration instead of fermentation?Cellular respiration produces more energy (ATP) than pare and discuss how cells store energy and release energy using ATP. Be specific! You may draw the cycle.Cells use ATP as their primary energy carrying molecule. Energy is released when the bond between the 2nd and 3rd Phosphate group is broken. This produces ADP. Energy is stored when this same bond is made, producing high-energy pare and discuss how cells use ATP and simple sugars in different ways.Simple sugars, such as glucose, are used as the primary energy-storing compound. Through aerobic respiration and fermentation, simple sugars are converted into ATP. ATP is the primary energy storing compound for all cells. It provides energy to all chemical reactions. Further explained: glucose is much more efficient at storing large amounts of energy. However it is more complicated to release the energy from glucose. For this reason glucose is converted into ATP which is then used by the cell to power its chemical reactions.Tell the kind of fermentation used in each example: Yeast use this to make bread dough rise __alcoholic fermentation______Your muscle cells use this during rapid exercise when oxygen is low lactic acid fermentationBacteria and yeast use this to make beer and wine __alcoholic fermentation______Bacteria use this to make cheese, yogurt, and sour cream lactic acid fermentationCellular Energy and the EnvironmentWhich chemical reaction, carried out by plants, removes CO2 from the atmosphere?photosynthesisWhich chemical reaction, carried out by all living organisms, releases CO2 back into the atmosphere? Respiration (aerobic & anaerobic)What is carbon fixation? Conversion of inorganic carbon to organic carbonWhich organisms perform carbon fixation? autotrophsWhat is the name of the chemical reaction in which this process occurs? Calvin cycle/photosynthesis ................
