Cellular Respiration & Photosynthesis
Cellular Respiration:
Glycolysis - O2 absent (Anaerobic, fermentation-lactic acid, ethanol)-O2 present- Pyruvate oxidation (Aerobic)-kreb cycle- ETC & Chemiosmosis
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP (flip the arrow to turn into photosynthesis
Electrons during cellular respiration come from NADH & FADH2
When electrons move from the membrane, they become H2O
2nd protein complex breaks down NADH
Hydrogen has a HIgh concentration between matrix
Cellular Respiration
Fermentation: is a partial degradation of sugars that occurs without oxygen and yields ATP
Aerobic Respiration- consumes organic molecules and oxygen and yields ATP
Redox Rxn- Electron donor= reducing agent. Electron Acceptor = oxidizing Agent
Oxidative phosphorylation- is powered by redox reactions
Substrate-level phosphorylation- occurs when an enzyme transfers a phosphate group form a substrate to ADP
Krebs Cycle- has to spin 2x
cytochromes- are carrier molecules that contain metals that make electrons in the ETC, flow easier
Photosynthesis
sunlight is used to synthesize foods from carbon dioxide & water
Light- dep rxn- occurs in the thylakoid membrane, re continuos supply of light energy, H2O is converted into O2, light energy is converted into ATP + NADPH
Calvin Cycle- takes place in the stroma of the plant, does not reg light & uses ATP + NADPH to make glucose
Three steps to Calvin Cycle- carbon fixation, reduction stage, & regeneration stage
Carbon Fixation & Reduction
Carbon fixation- RuBP-Ribulose 1,5- Biphosphate; G3P-glyceraldehyde-3-phosphate
Reduction- ATP & NADPH are used to convert 3-PGA into G3P, each molecule of 3-PGA receives a phosphate from ATP to make a carbon intermediate molecule
Regeneration- some G3P molecules go in to make glucose, while others must be recycled to regenerate the RUBP acceptor
3 Turns of Calvin Cycle= 1G3P, 2G3P= 1 Glucose, 6 Turns of Calvin Cycle= 1 glucose
