Cellular RespirationGetting Energy to make ATP!
Plant Energy vs. Animal EnergyWhat would we look like if we had chlorophyll in our skin?What if all our energy was from photosynthesis?Luckily, it isnt! Our mitochondria break down materials to give us energy!
Cellular RespirationWhere? MITOCHONDRIAWhat? BREAKS DOWN FOOD TO MAKE ATPHow?1) GLYCOLYSIS2) CITRIC ACID CYCLE3) ELECTRON TRANSPORT CHAINWhy? TO GET ENERGY in the form of ATP!!!!
O2D2-Hehe-a little Star Wars humorget it? R2D2ANAEROBIC-no oxygen requiredGLYCOLYSIS
AEROBIC-oxygen requiredCITRIC ACID CYCLEELECTRON TRANSPORT CHAIN
GLYCOLYSIS - glycolysisWhere? CytoplasmWhat? A series of chemical reactions that break down glucoseHow? Breaks down glucose into 2 molecules of pyruvic acidWhy? To make pyruvic acid, ATP, and NADH!p. 238
This is important.
Citric Acid Cycle (Krebs Cycle)Where? MitochondriaWhat? Breaks down acetyl-CoA to form ATP, NADH, FADH2, and CO2Why? Drives ETC to make huge amounts of ATP!!!p. 239
ELECTRON TRANSPORT CHAINWhere? Inner membrane of mitochondriaWhat? Energized electrons move from protein to protein to O2How? NADH and FADH2 give up electronsWhy? To make 32 ATP!!!p.240
ATP FROM 1 GLUCOSE MOLECULE
FERMENTATIONWhen? When cells are short on oxygenWhat? Anaerobic process that follows glycolysis until oxygen is available.How? Lactic Acid Fermentation (muscles) Alcoholic Fermentation (Yeast)Why? To produce ATP when oxygen is low
FERMENTATION(ITS ANAEROBIC!)LACTIC ACIDGlucose
Lactic Acid + 2ATP
Occurs in bacteria, plants, and animalsResults in muscle fatigue and sorenessALCOHOLICGlucose
Alcohol + 2ATP + CO2Yeast do it
