PPT-Diffusion, Osmosis and Cellular Respiration

Mr Greenberg Warm Up 2201 Suns energy6CO 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 . 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:. . Intermediate 2 Biology. Unit 1: Living Cells. Diffusion. Learning Objectives. Name the method by which substances move in and out of cells.. Define the term . ‘. diffusion. ’. State when diffusion will stop.. . Really smelly demonstration…... Put a few drops of vanilla in a balloon. Shake the balloon, then wait about 30 seconds. Smell the outside of the balloon. What’s going on?. EVIDENCE. INFERENCE. Osmosis. When the diffusing substance is water, and when the diffusion takes place through a semi permeable membrane the process is called osmosis.. Also the movement of water down a concentration gradient from an area of high solvent concentration (weak solution) to an area of low solvent concentration (stronger solution.). 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 . 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?. Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Concentration gradient. Concentration Gradient - change in the concentration of a substance from one area to another.. GK-12 Workshop II. Ashley . Vorhees. and Sarah Park. Cesar E. Chavez High School. Cricket Respiration Lab. Water level. Pipette. Students will measure oxygen consumption in crickets at different temperatures using simple . 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. Oxidative Phosphorylation. Figure 9.16. Electron shuttles. span membrane. MITOCHONDRION. 2 NADH. 2 NADH. 2 NADH. 6 NADH. 2 FADH. 2. 2 FADH. 2. or. . 2 ATP. . 2 ATP. . about 26 or 28 ATP. Glycolysis. 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. 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. 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.
