PPT-Diffusion, Osmosis and Cellular Respiration

Mr Black Warm Up February 10 2016 What is an organelle During a chemical reaction Reactants increase while the products decrease Reactants decrease while the products increase Products always equal the reactants . The Cell in its Environment. Ch 7, Section 2. L3 Biology. Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Diffusion. Movement of molecules from an area of high concentration to an area of lower concentration . CHAPTER 2/ O’LEVEL BIOLOGY 5090 / GCE.. 2. Diffusion and osmosis. Content. 2.1 Diffusion. 2.2 Osmosis. 2.3 Active . transport. Learning outcomes. Candidates should be able to:. (a) define diffusion as the movement of molecules from a region of their higher concentration to a region of. 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. Keywords: lactic acid, exercise, muscles, energy, cramp. B2 Topic 2 Organisms and Energy. This topic looks at:. Respiration – aerobic and anaerobic. Photosynthesis and limiting factors. Organisms and their environments. Mr. Greenberg. Warm Up 2//201. Sun’s energy+6CO. 2. +6H. 2. O. C. 6. H. 12. O. 6. +6O. 2. Where in the plant cell would you expect to find this reaction? . How many CO. 2. molecules are in this reaction? . 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?. . SIMPLE DIFFUSION. WHAT IS DIFFUSION. Diffusion is the movement of molecules or particles from a region of high concentration to a region of low concentration. . . 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. 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. Photosynthesis. Photosynthesis. is the process by which plants, some . bacteria use . the energy from sunlight to produce sugar and starches ……which . cellular respiration. converts into . ATP. 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. 2. Diffusion and osmosis. Content. 2.1 Diffusion. 2.2 Osmosis. 2.3 Active . transport. Learning outcomes. Candidates should be able to:. (a) define diffusion as the movement of molecules from a region of their higher concentration to a region of. 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.
