Cellular Respiration: ATP Production What is ATP? -stands for Adenosine Triphosphate. -often called the “molecular unit of currency” -a chemical compound which cells use to store energy or to release energy. -consists of the adenine‚ ribose sugar‚ and 3 other phosphate groups. ATP’s main purpose is to transport chemical energy within cells for metabolism. In this production‚ the Mitochondrion is the production centers of ATP. NADH and FADH2 • Are electron carriers that

In the Krebs cycle‚ the oxidation of glucose that began with glycolysis is completed. 3. In the electron transport chain‚ NADH is use to make ATP. 4. In prokaryotes the reactions take place in the cytoeol. 5. In eukaryotes the reactions take place in the mitochondria. 6. The mitochondrial

Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the metabolic process that releases stored energy from the bonds of organic molecules‚ mainly glucose. There are three stages: 1) Glycolysis 2) Krebs Cycle (Citric Acid Cycle) 3) Electron Transport Chain What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis splits the glucose

performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration by putting the syringes in box containing

Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The main function of cellular respiration is to generate ATP for cellular work; it is the process of harvesting chemical energy from organic fuel and converting it to ATP energy. The three stages of cell respiration include: Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis

Chapter 4 Microscopes Two important factors in microscopy are: 1) Magnification: an increase in the object’s apparent size compared with its actual size. 2) Resolving Power: the ability of an optical instrument to show two objects are separate. Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0
