Chapters 8 & 9: Photosynthesis & Respiration. Aka: Energetics. TOP. Secondary Consumers. Energy Pyramid. PRIMARY CONSUMERS. PRODUCERS. Where do we get all our energy from? Ultimately from the Sun By what process do we get this energy?. Photosynthesis.

By what process do we get this energy?
C6H12O6+ O2 + H2O
is a mixture of all the wavelengths (colors) of visible
3 phosphate groups
occurs only in the presence of light.
This one is my favorite!
can occur in light or darkness. Follows light reaction
THE LIGHT REACTION
NADPH & ATP are formed
5) The hydrogen (from NADPH) is taken to the stroma along with the grana's remaining light energy (ATP).
6) Carbon dioxide enters the leaf and passes into the chloroplast.
7) In the stroma the remaining light energy (ATP) is used to combine hydrogen (from NADPH) and carbon dioxide to make carbohydrates. This occurs during the Calvin Cycle
8) The energyrich carbohydrates are carried to the plant's cells.
9) The energyrich carbohydrates are used by the cells to drive the plant's life processes.
aka: Getting energy from the cake
The plant takes the raw materials (CO2 & H2O), puts them together using energy (heat), & synthesize the cake.
In order to get the energy out of the cake, the plant & us must ingest it (eat), digest it (break it down into its monomers) & then we must “burn it” to release the energy stored in the bonds of the cake.
THIS IS RESPIRATION
of Eukaryotic organisms
Respiration occurs on the Cristae
C6H12O6 + 6O2 6CO2 + 6 H2O + 36 ATP
C6H12O6 2CO2 + 2 Ethanol + 2 ATP
C6H12O6 2Lactic Acid + 2 ATP
Glucose (6 Carbons) is broken down into 2 Pyruvic (3 Carbons each) acid molecules + 2 ATP (activation energy)
Produces 4 ATP, netting 2 ATP
1. Alcohol + CO2 (if yeast & some bacteria)
2. Lactic Acid (some bacteria)
Both forms will not produce any more ATP molecules
Used in baking, wine making & brewing industry
Lactic acid production is used in cheese processing, buttermilk, sour cream, yogurt, sauerkraut, pickles. The souring of dairy products is actually the production of lactic acid by anaerobic bacteria
Using 2 ATP as activation energy, a glucose molecule is broken down into 2 Pyruvic Acid molecules. 4 ATP are produced, leaving 2 ATP netted Occurs in cytoplasm
2. Krebs Cycle – in the Mitochondria, the 2 Pyruvic acids are broken down, releasing CO2 & producing 2 ATP
3. Electron Transport Chain – Oxygen combines with hydrogen
32 ATP are produced
2 Carbon Dioxides
Aerobic respiration yields 2 + 2 + 3236 ATP
Anaerobic respiration yields 2 ATP 2 ATP _______
Aerobic Respiration is 18x’s more efficient!!!
