PPT-Cellular Respiration Chemical Energy and Food

Food is the energy source for cells The energy in food is measured in calories A calorie is the amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius There are 3811 calories in one gram of sugar glucose. ENERGY IN THE CELL. ENERGY IN THE CELL. ENERGY CONVERSIONS. PHOTOSYNTHESIS. CELLULAR RESPIRATION. ATP for cell usage. Is about. Starting with. Transformed by. Converted to. Plants & photosynthesis. Chap 9: Cellular Respiration. THINK ABOUT IT. You feel weak when you are hungry because food serves as a source of energy. . How does the food you eat get converted into a usable form of energy for your cells?. to . Describe Cycle of Matter and Energy in. Organism and Ecosystems. Created . by:. D. Peters. MS LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. [Clarification Statement: Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released.] [Assessment Boundary: Assessment does not include details of the chemical reactions for photosynthesis or respiration.]. Photosynthesis. - the process of absorbing light energy and converting it into stored chemical energy.. Chemical equation:. Cellular Respiration. - the breaking down of a food substance into usable cellular energy in the form of ATP. Outline. I. Photosynthesis. A. Introduction. B. Reactions. II. Cellular Respiration. A. Introduction. B. Reactions. What organisms go through photosynthesis?. Producers/autotrophs. , . such as plants, trees, algae, some bacteria. Key Concept. How do cells release the energy from glucose?. Agree or Disagree. Cellular respiration only occurs in lungs . cells. Disagree. Without oxygen cellular respiration cannot continue. .. Disagree. Levels of Organization. Since ene. rgy is always lost as it is transferred. , the amount of total energy (or biomass) decreases as we move up the pyramid.. There will always be a much . greater overall number of producers. Let’s review!!. The Role of ATP, Photosynthesis, and Cellular Respiration. Write this at the top of page . Would you rather . have 50 $1 bills or 1 $50 bill? Make a decision and provide 3 reasons why. Cell Respiration. Cell. Breathing. O. 2. Cellular respiration carried out in 2 stages: . Glycolysis and Oxidation. The equation for cellular respiration is the opposite of the equation . for photosynthesis. Cellular Respiration:. During the respiration reaction glucose bonds are broken and the carbon is released to form CO2. . (Use the NAMES of the molecules) According to your equation, the process of cellular respiration uses ____________________ and ___________________ to produce ________________________, ___________________ and release ____________________.. WHAT IS CELLULAR RESPIRATION?. Metabolic reactions in the cell that are designed to convert nutrients from food into Adenosine Triphosphate (ATP). Carbohydrates, fats, and proteins can all be used as fuel. Energy releasing process in . which organisms . take in glucose and oxygen and produce carbon dioxide, water and ENERGY. Materials needed for respiration. Glucose (sugar). Oxygen. Products of respiration. These . organisms are called HETEROTROPHS or CONSUMERS. . . Some Organisms use sunlight to make food in a process called photosynthesis:. Some . organisms cannot use sunlight to make . food-they . is the set of chemical reactions that happen in all cells of living organisms to sustain life. . Metabolism is all about . staying alive. . . The reactions of metabolism that take place in our bodies are to maintain growth and normal functioning. .
