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 . . Notes. Energy:. Energy for living things comes from . food. . Originally, the energy in food comes from the . sun. .. Organisms that use . light energy. from the sun to produce food—. autotrophs. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. . 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. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. . 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. Overview of . Cellular Respiration. the . process that releases energy by breaking down glucose and other food molecules in the . presence . of . oxygen. This is an . aerobic. process, meaning that it requires oxygen. . 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. 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. Respiration can be considered the opposite process of photosynthesis. It is the transformation of food energy into chemical energy in the form of ATP. Plants and animals go through the same process of cellular respiration. What is the path of carbon from CO. 2. in the air into coal deep in the earth?. Burning Fossil Fuels has the . SAME. formula . as Cellular Respiration. . C. 6. H. 12. O. 6. + 6 0. 2. —>  6 CO. 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. 1. Cellular respiration. Cellular respiration and fermentation. Fermentation = An ATP-producing catabolic pathway in which both electron . donors . and . acceptors are organic compounds.. • Can be an anaerobic process.
