Question 2

What consits of stage 1 on photosynthesis and where does it happen

Answer 2

Occurs in the thylakoid membrane and lumen, consists of chemiosmosis and non cyclic cycle

Question 3

Why is it called non-cyclic

Answer 3

The electrons never return back to starting place so its basically one way trip

Question 4

What are the products and reactants of the noncyclic cycle

Answer 4

Reactants: Photon (sunlight), H+ and NADP+, ADP+Pi, chlorophyll, water
Products: NADPH, ATP, Oxygen

Question 5

Explain the process of chemiosmosis and non-cyclic cycle

Answer 5

• Photon strikes the PS11, exciting the electron
• Two water molecules bind to enzyme Z which split them up into H+ (protons) and Oxygen as waste
• PQ picks up that excited electron
• PQ passes the electron to the b6-f complex, which pumps are H+ into the thylakoid space. this is done using the energy from the electron
• H+ gradient leads to the synthase of ATP via the ATP synthase - because of PMF and chemiosmosis
• The electrons are picked up by PC, which passes it to PSI, which is again stuck by photons
• The excited electrons are picked up by Fd (ferdoxin) which are bought to the NADP+ reductase, which will make NADPH.
