Photosynthesis by Mind Map: Photosynthesis

1. 6 CO2 + 6 H20 -------> C6H12O6 + 6O2

2. Chloroplasts

2.1. Inner and Outer Membranes Enclose STROMA-Interior Compartment

2.2. Contains THYLAKOIDS

2.2.1. called GRANA when stacked together

2.2.2. consist of THYLAKOID MEMBRANE and THYLAKOID SPACE

3. Light Dependent Reactions

3.1. Convert light energy into chemical energy in the form of ATP and NADPH H2O--->O2

3.2. Occurs in CHLOROPLAST

3.3. When pigment ABSORBS LIGHT, ELECTRONS EXCITED TO HIGHER ENERGY STATE

3.3.1. Energy is transferred until it reaches the REACTION CENTER CHLOROPHYLL P680

3.3.1.1. Photosystem II

3.3.1.1.1. Located in THYLAKOID MEMBRANE

3.3.1.2. ELECTRONS ARE EXCITED and TRANSFERRED to PRIMARY ELECTRON ACCEPTOR ALONG WITH ELECTRONS TAKEN FROM WATER

3.3.1.2.1. H+ are generated and MOVED TO THE INSIDE OF THE THYLAKOID

3.3.1.2.2. PRIMARY ACCEPTOR PASSES ELECTRONS ONTO ELECTRON TRANSPORT CHAIN

3.3.2. PIGMENT MOLECULE CHLOROPHYLL A

3.3.2.1. primary pigment involved in absorbing light energy.

3.3.2.2. Absorbs RED AND BLUE wavelengths of light

3.3.2.2.1. High transmittance of GREEN light

3.3.2.3. PORPHYRIN RING-light absorbing "head" of molecule with Mg

3.3.2.3.1. HYDROPHOBIC tail

4. Light Independent Reaction: The Calvin Cycle

4.1. CO2 is joined with a sugar (carbon fixation), reduced (NADPH is oxidized), and sugar is produced

4.1.1. REQUIRES ATP

4.2. Occurs in STROMA

4.3. CARBON FIXATION

4.3.1. CO2 is taken DIRECTLY from atmosphere and added to 5-Carbon molecule called RIBULOSE BISPHOSPHATE

4.3.1.1. via RUBSICO enzyme

4.4. 3 CO2 ENTER

4.4.1. ADDED TO RIBULOSE BISPHOSPHATE via RUBISCO

4.4.1.1. 3 SHORT-LIVED INTERMEDIATES ARE CREATED

4.4.1.1.1. BREAKS APART TO FORM 6 3-PHOSPHOGLYCERATE s

4.5. 1 CYCLE REQUIRES 9 ATPs and 6 NADPH from LIGHT REACTION

4.5.1. this makes HALF a GLUCOSE molecule

4.6. MUST GO THROUGH CYCLE TWICE TO PRODUCE ONE GLUCOSE

4.7. RETURNS NADP+, inorganic phosphate, and NADP+ to LIGHT DEPENDENT REACTIONS
