ADENOSINE TRI-PHOSPHATE Energy stored in the phosphate bond.
Plant cells have both chloroplasts and mitochondria! Photosynthesis takes place in chloroplasts Cellular Respiration takes place in mitochondria All other Eukaryotes only have mitochondria!
What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for cellular respiration? GLUCOSE
Photosynthesis Why are Photosynthesis and Cellular Respiration Opposites? Cellular Respiration
Photosynthesis Reactants of one are products of the other!!!! Reactants Products Cellular Respiration
What is the equation for Cellular Respiration? (Hint: Think Photosynthesis in reverse) Must know this equation!!!!
Once a cell has glucose, what process takes place to convert the glucose into 2 ATP (energy) and 2 Pyruvates? Glycolysis • Where does this process take place in the cell? • Cytoplasm
What type of living things do Glycolysis? STEP #1 of Cellular Respiration Animals Plants Protists Fungi Bacteria NADH 2 3 Kreb’s Cycle Electron Transport Chain 1 Glycolysis All living things do glycolysis!!!! Most bacteria only use glycolysis to make 2 ATP’s and don’t need more to function because they are so small. 2 ATP
4 ATP’s are made but 2 ATP’s go back into Glycolysis Net 2 ATP’s 2 Pyruvates (Pyruvic Acid) NAD+ → NADH (energy carriers) ADP → ATP (chemical energy) Glycolysis takes place in the cytoplasm and needs ATP to break 1 Glucose→ 2 PGAL’s
CYTOPLASM Oxygen present Cellular Respiration (aerobic) 2 Pyruvates Oxygen not present Anaerobic Fermentation Anaerobic Fermentation (Lactic Acid or Alcoholic)
AnaerobicFermentation (no oxygen) takes place in the Cytoplasm Alcoholic - Yeast Lactic Acid – Animal Muscles Important Product of Fermentation = 2 NAD+
GLYCOLYSIS – In Cytoplasm STEP #1 Mitochondria Kreb’s Cycle takes place in the Matrix (space )of the Mitochondria STEP #2 Matrix STAGE 2 Electron Transport Chain takes place in the INNER MEMBRANE of the Mitochondria STAGE 3 STEP #3 Inner Membrane Hint: “Cycles take place in the SPACE” (Matrix)
Step #2: Kreb’s Cycle: What products are made? CO₂, NADH, FADH₂, 2ATP Charged Battery Charged Batteries NADH FADH2 NADH 2 3 1 Kreb’s Cycle Citric Acid Cycle Glycolysis 2 Pyruvates CO₂ out 2 ATP 2 ATP
Step #3: Electron Transport Chain: NADH, FADH₂, O₂ goes in H₂O, ATP comes out Charged Battery NADH FADH2 NADH O₂ in 2 3 1 Kreb’s Cycle Citric Acid Cycle Glycolysis 2 Pyruvates Electron Transport Chain H₂O out 32 ATP CO₂ out 2 ATP 2 ATP
