What are the types of reactions in photosynthesis? - Answers -✔✔ Light and Dark
Reactions (Calvin Cycle)
What are the reactants of the light reactions of photosynthesis? - Answers -✔✔ Water
H+ ions
Light Energy
, What are the products of the light reactions of photosynthesis? - Answers -✔✔ ATP
(gets used for Calvin)
NADPH (gets used for Calvin)
Oxygen (gets released)
What are the reactants of the dark reactions of photosynthesis? - Answers -✔✔ ATP
NADPH
CO2
What are the products of the dark reactions of photosynthesis? - Answers -✔✔ ADP +
Pi (gets used for light reactions)
NADP+ (gets used for dark reactions)
Sugar (gets released)
Where is oxidative phosphorylation used? - Answers -✔✔ Final step of Cellular
Respiration
Electron Transport Chain (mito matrix ->inner mito. membrane)
ATP Synthase
Proton Pumping (inner mito. membrane ->intermembrane space)
What happens in oxidative phosphorylation? - Answers -✔✔ 1) H+ ions go against their
concentration gradient through proteins
2) movement of H+ ions fuel oxidation of NADH to NAD+ and simultaneously help
create H20
3) H+ ions are now in the intermembrane space
4) They go down their concentration gradient into ATP Synthase
5) ATP Synthase acts as a water mill and the movement of the H+ ions fuel the creation
of ATP from ADP
Where is substrate level phosphorylation used? - Answers -✔✔ Glycolysis and Krebs
Cycle
What happens in substrate level phosphorylation? - Answers -✔✔ ATP Synthesis
Requires a transfer of a high energy phosphate group from a substrate to an ADP. This
transfer of high energy will result in a change from ADP to ATP.
What is the difference between oxidative phosphorylation and substrate level
phosphorylation? - Answers -✔✔ Oxidative Phosphorylation uses electrons and the
electron transport chain to generate ATP
Substrate Level Phosphorylation uses the energy of the phosphate groups to generate
ATP
Oxidative Phosphorylation generates more ATP (30-32)
Oxidative Phosphorylation requires energy, Substrate Level Phosphorylation does not
(why it's able to work in Glycolysis and Krebs)
