What is/are the overall function(s) of photosystem II? What is/are the overall function(s) of the Calvin cycle?   Q3: Are the compounds listed here used or produced in: Photosystem I?Photosystem II?The Calvin cycle?Glucose O2 H2O CO2 ATP ADP + Pi NADPH NADP+  C3 plants- stressful environments can and will kill these plants eventually. Ex. Fern Q4: Why do stressful environments affect C3 plants? Explain photorespiration and why is this considered a quick fix for the plant? Why is photorespiration an inefficient and wasteful method of carbohydrate production Some call photorespiration a mistake in the functioning of the plant cell? Explain the Pros & Cons to that statement C4 plants: these plants have a net photosynthesis rate of 2-3x as much as a C3 plant in a stressful environment. Ex. Corn Q5: How PGAL produced in a C4 plant? What differs between C3 and C4 plants when their stomates close? How is photorespiration avoided by C4 plants? CAM plants: These plants thrive in very harsh environments. Ex. Cactus Q6: How do these plants conserve water? How does the compound Malate contribute to the resistance of photorespiration by CAM plants? What compound is reduced into PGAL by CAM plants Q7: What makes C4 photosynthesis more efficient than C3 photosynthesis in tropical climates? Q8: What makes C3 photosynthesis more efficient than C4 photosynthesis in temperate climates? Q9: What makes CAM photosynthesis most efficient in desert climates? ./3s5 6 o p q v y z {           źź뤘ŤŤŤźźźźźźhaVhG4CJPJaJhaVhG46PJ]haVhG4PJhaVhG4B*PJphhaVhG4CJaJ haVhG4CJOJPJQJaJhaVhG4B*PJphh'8hG4 h'85\ hG45\ hU5\6./s % 5 6 N h o p $Ifl $7$8$H$IfgdaVl gdG4$a$p q r s t u v w `IIIIII$7$8$H$IfgdaVl kd$$IflF) ,"h h h  t06    44 lapytaVw x y z {  PKKgdG4kd$$IflF) ,"h h h  t06    44 lapytaV$Ifl  $Ifl $7$8$H$IfgdaVl  E55555$Ifl kd`$$Ifl\I ," F F F  t0644 lBap(ytaV H88888$Ifl kd $$Ifl\I ,"     t0644 lap(ytaV   H88888$Ifl kd$$Ifl\I ,"     t0644 lap(ytaV    H88888$Ifl kd$$Ifl\I ,"     t0644 lap(ytaV      H88888$Ifl kdN$$Ifl\I ,"     t0644 lap(ytaV    !
