Exam 2 Flashcards
Photorespiration
A series of reactions in which O2 is attached to RuBP, eventually resulting in the release CO2 from the plant
Rubisco
An acronym for the enzyme ribulose-1,5 - bisphosphate carboxylase/oxygenase
Light Reactions
Light Energy Driven
Water provides electrons and protons
Enery stored as ATP and NADPH
Dark Reactions
CO2 converted to carbohydrates
ATP and NADPH provides energy

Sucrose
A soluble disaccharide containing a glucose and a fructose residue
Photosystem II (PSII)
Light Harvesting Complex
Reaction Center → P680
Water Splitting or Oxygen Evolving Complex
Main Products of PSII Reaction
H2O & O2
Photosystem I (PSI)
Light Harvesting Complex
Reaction Center → P700
Accepts electrons from PC
Electrons passed to ferredoxin (Fd)
Electrons in Fd donated to NADP+ at the Ferredoxin NADP Reductase Complex to produce NADPH
Main Products of PSI Reaction
NADPH
Main Substrate of PSII Reaction
H2O
Main Product of Calvin Cycle
Glucose
