converts solar energy into the chemical energy of a carbohydrate- Solar energy + 6CO2 +6H2O = C6H12O6 + 6O2. Organisms include plants, algae and certain bacteria.
Chemical reactions which involve a partial or complete transfer of electrons. Called redox reactions.
OIL RIG / LEO says GER
Oxidation Is Loss of elections, Reduction Is Gain of electrons / Loss of Electrons is Oxidation, Gain of Electrons is Reduction
enzyme that adds P directly onto ADP to make ATP- used for quick energy, anaerobic, occurs in cytoplasm
The breakdown of glucose by the removal of hydrogens- used for short term energy production, anaerobic, occurs in cytoplasm- produces 2 molecules of pyruvate
Lactic Acid Fermentation
Animal cells. Pyruvic acid is converted to 3 carbon lactic acid. Diffuses into blood, transported to liver and converted back to pyruvic acid when oxygen is present.
Plant cells and yeast convert pyruvic acid to ethyl alcohol (ethanol) and CO2
Occurs in the matrix, pyruvate combines with coenzyme A (CoA) to produce acetyl CoA. 2 NAD is reduced to NADH + H. 2 CO2 is released.
used for long term energy production, aerobic, occurs in mitochondria matrix, can use glucose, fats or proteins as fuel.
Citric Acid cycle- Acetyl CoA combines with 4C. 6C is oxidized as NAD reduced to NADH, CO2 removed. 5C is oxidized as NAD reduced to NADH, another CO2 is formed, ATP is generated. 4C is oxidized as FAD and NAD reduced to FADH2 and NADH. 4C molecule.
protein that uses energy released by movement of protons down concentration gradient to make ATP
absorb different wavelengths of light from chlorophyll. They appear red, yellow and orange to us.
Light dependent reactions step 4
Light excites e- in photosystem I and move to an e- acceptor. e- are replaced by e- from photosystem II.
Light dependent reactions step 5
e- are transported along another ETC and combine with NADP+ to make NADPH
Restoring photosystem II
enzyme in thylakoid splits water into protons, electrons and oxygen. Electrons replace photosystem II, protons are left inside thylakoid, oxygen diffuses.
