LIGHT DEPENDENT
WHERE DOES THE LIGHT DEPENDENT REACTION OCCUR?
WHERE DOES THE LIGHT INDEPENDENT REACTION OCCUR?
- THYLAKOID MEMBRANE
- STROMA
THE REACTANS OF THE LIGHT DEPENDENT REACTION ARE
NADPH
ATP
LIGHT
H2O
WHAT ARE THE PRODUCT(S) OF THE LIGHT INDEPENDENT REACTION?
1 G3P
WHICH IS FORMED FIRST: G3P OR 3-PGA
3-PGA
THIS TYPE OF ORGANISM MAKES THEIR OWN FOOD USING LIGHT
PHOTOAUTOTROPH
SOLAR ENERGY IS ABSORBED USING WHAT?
PIGMENTS
WHICH WAVELENGTH/COLOR HAS HIGHER ENERGY.
BLUE OR ORANGE
BLUE
THE CALVIN CYCLE CAN BE BROKEN DOWN INTO THREE STAGES, WHAT ARE THESE & PUT THEM IN CORRECT ORDER.
1. CARBON FIXATION
2. REDUCTION
3. REGENERATION
WHAT IS CARBON FIXATION "FIXING" & HOW DOES THIS PROCESS DO THIS?
- USES AN ENZYME KNOWN AS RUBISCO
THIS IS THE PREDOMINANT PRODUCER OF OXYGEN ON THE PLANT
PHYTOPLANKTON
THE THREE CATEGORIES OF PIGMENTS IN PLANTS ARE
CHLOROPHYLL A
CHLOROPHYLL B
CAROTENOIDS
IN BOTH PHOTOSYSTEMS ELECTRONS ARE FIRST PASSED FROM P680 AND P700 TO A:
PRIMARY ELECTRON ACCEPTOR
THE REDUCTION STAGE OF CALVIN CYCLE USES WHAT TWO MOLECULES TO CHANGE 3-PGA INTO G3P
- NADPH
- ATP
HOW MANY CO2 MOLECULES MUST ENTER THE CALVIN CYCLE TO PRODUCE 1 G3P MOLECULE?
3 CO2
H+ IONS DIFFUSING DOWN ATP SYNTHASE IS AN EXAMPLE OF ACTIVE OR PASSIVE TRANSPORT.
(+100 - WHAT SPECIFIC TYPE OF TRANSPORT IS THIS)
- FACILITATED DIFFUSION
ELECTRONS FROM PSI ARE USED TO REDUCE WHAT INTO WHAT
NADP+ INTO NADPH
PUT THIS IN CORRECT ORDER:
1. ELECTRON IS PASSED TO A PRIMARY ELECTRON ACCEPTOR
2. ELECTRONS ARE USED TO REDUCE NADPH
3. ELECTRON IN PS1 IS ENERGIZED BY A PHOTON
4. AN ELECTRON FROM PS2 IS USED TO REPLACE ONE LOST IN PSI
3. --> 1. --> 2. --> 4.
DESCRIBE THE REGENERATION STEP OF THE CALVIN CYCLE
5 G3P ARE REARRAGNED USING ATP TO FORM 3 RUBP
WHICH PROCESS IS CATABOLIC AND WHICH IS ANABOLIC - PHOTOSYNTHESIS & CELLULAR RESPIRATION
PHOTOSYNTHESIS - ANABOLIC
CELLULAR RESPIRATION - CATABOLIC
DESCRIBE THE DIFFERNECE BETWEEN OXIDATIVE PHOSOPHORLATION AND PHOTOPHOSPHORYLATION
OXIDATIVE - OXIDIZE NADH & FADH2 TO HELP ATTACH A PI TO ADP AND MAKE ATP
PHOTO - USE LIGHT TO HELP ATTACH PI TO ADP AND MAKE ATP
DESCRIBE HOW AN ETC IS USED TO PRODUCE ATP. (INCLUDE CONCENTRATION GRADIENT, STROMA, LUMEN)
ELECTRONS ARE PASSED THROUGH AN ETC, WHERE THEY RELEASE ENERGY INTO A CYTOCHROME MOLECULE. THIS HELPS PUMP H+ FROM THE STROMA INTO THE LUMEN. HIGH CONCENTRATION OF H+ IN THE LUMEN. H+ THEN DIFFUSES DOWN ATP SYNTHASE
WHAT WOULD OCCUR IF THE MEMBRANE WAS LEAKY TO H+ IONS?
THE CONCENTRATION GRADIENT WOULD NOT BE ESTABLISHED AND ATP COULD NOT BE FORMED.
PREDICT WHAT WOULD OCCUR IF NADPH IS UNABLE TO REDUCE 3-PGA
- NO G3P WILL BE FORMED
- THE LIGHT DEPENDENT REACTION WILL BREAK DOWN AS THERE IS NO NADP+
DESCRIBE HOW RUBP IS ALTERED AND ULTIMATELY REGENERATED THROUGH THE CALVIN CYCLE
RUBP --> 3-PGA --> G3P --> RUBP
DURING CELLULAR RESPIRATION TO PRODUCE ATP
