Chapter 9- Cellular Respiration & Metabolism Life is Work! Living Cells- we all require transfusion of energy from the outside For us- it comes from food Plant Friends- sun (light) Most ecosystems- flows in as sunlight & out as heat Panda- obtains energy from eating plants Catabolic Pathways Yield energy by oxidizing food Exergonic reaction- gives up energy Ex. Cellular Respiration Most efficient Take in food‚ break it down‚ yields energy Yield energy by transferring electrons Redox Reaction

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the

Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the aerobic harvesting of energy from food molecules. The first stage of cellular respiration is Glycolysis. The second stage of cellular respiration is the citric acid cycle. Lastly‚ the third stage of cellular respiration is the electron transport. • What is the role of glycolysis? Include the reactants

and cellular respiration make one large cycle that sustains life on earth. Through photosynthesis the suns energy is constantly being transformed into glucose‚ which is a chemical energy. Respiration is the chemical activity that occurs in all plants and animal cells that release the energy from the glucose. Photosynthesis cannot exist with cellular respiration‚ they are completely linked together in providing the energy through the food we eat. Cloud‚ D (2012). Photosynthesis and cellular respiration

Inside the body they preform cellular respiration‚ they take in nutrients from the cell‚ break it down‚ and turn it into energy. This energy is then used by the cell to carry out various life processes. Without this energy‚ none of the organelles within the cell would be able to function

questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process by which cells harvest energy that is stored in food. The three stages are glycolysis‚ citric acid cycle‚ and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis which mean splitting sugar‚ with oxygen it is the first step in cell respiration‚ without oxygen

and energy as follows: C5 H12 O6 2C3 H6 O3 + energy Anaerobic respiration is a stage of cellular respiration that happens in the absence of oxygen. The first step is the breakdown of glucose in glycolysis. During this step glucose is broken down to two pyruvic acid molecules. The fate of pyruvic acid depends on whether there is oxygen available or not. In the absence of oxygen‚ pyruvic acid continues the anaerobic respiration pathway and is converted into lactic acid. Only six ATP molecules
