Energy All organisms use energy to carry our the chemical activities that allow them to live, grow, and reproduce. Cellular Energy Cellular Respiration Photosynthesis 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 6CO2 + 6H20 + light energy C6H1206 + 602 (Food) Carbon dioxide Water Glucose (Carbs) Oxygen

I don’t have lungs to breath! 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 C6H12O6 + 6O2 6CO2 + 6H2O + ATP Glucose Oxygen Carbon dioxide Energy Water (Energy)

Metabolism All the chemical activities in the organism: Making food Breaking down food Moving material in/out of cells Building cells http://www.runnersweb.com/running/bmr.html http://www.runnersweb.com/running/RunnersWeb_External_Links.html?http://www.bodytrends.com/tools.htm

Fermentation Muscle Fermentation Lack of oxy. causes burning feeling Small amt. of ATP (energy) is made Released as lactic acid. Sugar Fermentation Yeast make CO2 and alcohol. Bubbles of CO2 form bread.
