Why do you get hungry?
Energy All organisms use energy to carry our the chemical activities that allow them to live, grow, and reproduce. Cellular Energy Photosynthesis Cellular Respiration Fermentation
Photosynthesis Occurs in plants and is bottom of food pyramid. Is the process of changing sunlight into energy (food).
Pigments Are molecules in plant cells that absorb the energy of light. Chlorophyll: the pigment that is green in chloroplasts.
Photosynthesis 6CO 2 + 6H light energy C 6 H (Food) Carbon dioxide Water Glucose (Carbs) Oxygen
Cellular Respiration Process of breaking down food so the energy from your food can be converted for cell use. Uses Oxygen Not the same as breathing. Oxy. is necessary for process & carbon dioxide is waste. Respiration happens in plants & animals I don’t have lungs to breath!
Cellular Respiration & Energy C 6 H 12 O6 + 6O 2 6CO 2 + 6H 2 O + ATP GlucoseOxygen Carbon dioxide Water Energy (Energy)
Metabolism All the chemical activities in the organism: Making food Breaking down food Moving material in/out of cells Building cells
Fermentation Muscle Fermentation Lack of oxy. causes burning feeling Small amt. of ATP (energy) is made Released as lactic acid. Sugar Fermentation Yeast make CO 2 and alcohol. Bubbles of CO 2 form bread.
Create a Venn Diagram describing how respiration and fermentation are similar and different.
