Organism is an autotroph http://www.inclusive.co.uk/downloads/images/pics2/tree.gif AUTOTROPHS ___________ use energy from sunlight or chemicals to make their own food (What type Organism is an autotroph In the last chapter green plants used ________________ to trap energy from __________ and make ______________ PHOTOSYNTHESIS sunlight food (glucose) http://206.173.89.42/REALTYWITHALOHA_COM/piphoto/funny%20sun%20with%20sunglasses.gif

In this chapter, we will learn how this carb/sugar is ____________ by organisms and the _______ is stored as _______ in a process called ___________________ broken down energy ATP CELLULAR RESPIRATION What kind of organisms do this?

What kind of organisms do this? plants fungi animals bacteria ________ (Including _______) ______ ______ ______ humans ALL LIVING THINGS NEED ENERGY!

How do we get the sugar from the plants? REMEMBER! _______________ get their energy by eating other organisms. HETEROTROPHS We get the energy the plants stored as glucose by _____________ directly or eating the _________ that ate the plants. eating plants animals  Image from: http://ag.ansc.purdue.edu/sheep/ansc442/Semprojs/2003/spiderlamb/eatsheep.gif http://www.cibike.org/Eating.htm

REMEMBER CELL BIO

Power plant of cell that burns glucose and stores the energy as ATP Image from: http://vilenski.org/science/safari/cellstructure/cytoplasm.html Power plant of cell that burns glucose and stores the energy as ATP = _______________ mitochondria http://www.clickatutor.com/mitochondria.jpg

MITOCHONDRIA = cell power plant Surrounded by ___________ membrane Outer membrane & Inner membrane (called _______________ ) Compare the structure of Chloroplast to Mitochondria: Similar, but Different. DOUBLE CRISTAE

All organisms (heterotrophs AND autotrophs) use the _____________ to  Image from: http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.html All organisms (heterotrophs AND autotrophs) use the _____________ to charge up their _______ energy in food ATP

energy from FOOD (glucose) to make _____ = ________________ This process of releasing the energy from FOOD (glucose) to make _____ = ________________ ATP CELLULAR RESPIRATION  Image by Riedell Image from: http://www.biologyclass.net/mitochondria.jpe  

slowly in ________________. many steps CELLULAR RESPIRATION happens __________ in ________________. If all the energy was released in one step… most would be lost as ____________________! slowly many steps light and heat http://plato.acadiau.ca/COURSES/comm/g5/Fire_Animation.gif  

PHOTOSYNTHESIS CELLULAR RESPIRATION 6 CO2 6 H2O C6H12O6 6O2 C6H12O6 ___________ + _________ + ___________ →_______________ + __________ 6 CO2 6 H2O C6H12O6 6O2 CELLULAR RESPIRATION C6H12O6 6 CO2 _____________ + _________ →________ + __________ + __________ ______________________________________________________________ 6O2 6 H2O The two equations are exact opposites!

Calorie UNITS FOR MEASURING HEAT ENERGY Food is Energy trapped http://hesperia.gsfc.nasa.gov/sftheory/images/boilingif UNITS FOR MEASURING HEAT ENERGY Food is Energy trapped Unit for measuring energy in food = _______________ Calorie http://www.raytechcatalog.com/images/products/mainstay_food_3600_nutrition.gif

Plants do ____________ but Flooded Corn Field photosynthesis By:http://skyways.lib.ks.us/towns/ElkCity/2007flood.html plants need ______________________ too. So plants do Photosynthesis to make their food, then they do cellular respiration to get energy from their food! Does that mean plants are cannibals?!! oxygen for cellular respiration

Factors Affecting Cellular Respiration Temperature – usually the rate of cellular respiration increases as temperature increases This is why you sweat more if its hot when you work out or dance or whatever you do to sweat. You are burning Food for energy, doing more cellular respiration

Factors that affect Cellular Respiration Glucose and Oxygen – The more reactants the cell has, the more energy it can produce What happens when you don’t eat enough? No Energy!!!! Weak!!!!

Check for Understanding Write the equation for Cellular Respiration. What is the name of the molecule the cell uses to store energy taken from sugar and other food? Besides sugar what does an organism need in order to do cellular respiration? What is the name of the organelle where cellular respiration takes place? If I am not feeling energetic what can I do to increase my cellular respiration?
