What is Cellular Respiration?
Cellular Respiration OverviewTransformation of chemical energy in food into ATP (chemical energy cells can use)These reactions proceed the same way in plants and animals. Process is called cellular respirationIt happens in the mitochondria
Glucose+ Oxygen Carbon Dioxide + Water + EnergyThe equation=Overall Reaction:C6H12O6 + O2 CO2 + H2O
CELLULAR RESPIRATION EQUATION: C6H12O6 + O2 CO2 +H2O +Energy
PHOTOSYNTHESIS EQUATION: CO2 + H2O + LIGHT C6H12O6 + O2
3 StepsThere are three steps in the process of cellular respiration: 1. Glycolysis2. Krebs Cycle (Citric Acid Cycle)3. Electron transport chain.

All 3 steps produce ATP. The electron transport chain produces the most!
Types of Cellular Respiration: Aerobic vs. AnaerobicAerobic- oxygen requiredAnaerobic- no oxygen requiredIf oxygen is not present, products such as ethanol and CO2 (single cell fungi (yeast) in beer/bread) or lactic acid (muscle cells) are produced.Some organisms thrive in environments with little or no oxygenMarshes, bogs, gut of animals, sewage treatment ponds

Steps in the process
Where it takes place
Gas ExchangeStoma- opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leafGuard cell- specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure
How it gets foodI can make my own food= A______.
I cannot make my own food=H____.

*********Digestive system in animals. Xylem (water), Phloem (food), Roots for plants.*Hormones in plants: How they respond to the environment. -Ethylene makes plants ripen. One bad apple can spoil the bunch. What happens when you put fruits or veggies in a bag? Ripen faster/rot. Light and gravity- phototropism.*Stoma- opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leafGuard cell- specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure
