Photosynthesis 1. If light intensity increases in an atmosphere of excess carbon dioxide, the limiting factor on the rate of photosynthesis is most likely to be: chlorophyll type light intensity temperature carbon dioxide concentration 2. In photosynthesis, carbon dioxide is fixed during: the light-dependent stage non-cyclic phosphorylation cyclic phosphorylation the light-independent stage 3. In photosynthesis, excited electrons leave a chlorophyll molecule during: the light-independent stage the light-dependent stage non-cyclic phosphorylation cyclic phosphorylation 4. In the light-independent stage carbohydrate is synthesized from: NAPD ATP PGA ADP 5. Phosphoglyceric acid (PGA) is formed when carbon dioxide is fixed onto the 5C compound: edenosine triphosphate ribulose bisphosphate adenosine monophosphate nicotinamide adenine dinucleotide phosphate 6. The first stable product of the Calvin Cycle is: PGA ADP NAPD ATP 7. The greenhouse effect is likely to: increase the rate of photosynthesis globally decrease the rate of photosynthesis globally reduce the rate at which carbon is incorporated into carbohydrate globally have no effect on the rate of photosynthesis globally 8. The two principal stages of photosynthesis are: the light-dependent and light-independent reactions photolysis and ATP synthesis photosystem I and photosystem II cyclic and non-cyclic phosphorylation 9. In photosynthesis, carbohydrates are produced during: the light-dependent stage the light-independent stage cyclic phosphorylation non-cyclic phosphorylation 10. In photosynthesis, oxygen is produced during: non-cyclic phosphorylation cyclic phosphorylation the light reactions the light-dependent stage
