Which of the following lists the stages of the Calvin cycle in order, starting with the stage where carbon dioxide is added? PGAL synthesis → carbon fixation → light reactions → regeneration of RuBP carbon fixation → PGAL synthesis → regeneration of RuBP regeneration of RuBP → carbon fixation → PGAL synthesis photorespiration → PGAL synthesis → regeneration of RuBP → carbon fixation

In a scientific experiment, thylakoids put in an acidic solution and then transfered to a basic solution were able to produce ATP. This was due to what process?   Question 40 options:   Photosystem I   Chemiosmosis   calvin cycle   Photosystem II

After electrons are raised to high energy levels in photosystem II, they travel down an electron transport chain.  As they are stepped down in energy, the lost energy is used to power which process.      The pumping of high energy electrons into the intermembrane space.  This creates a large difference in concentration and in electric charge between the intermembrane space and the lumen of the thylakoid.  When these high energy electrons rush back into the thylakoid lumen, they are forced to travel through one of the ATP synthase molecules that sits embedded in the thylakoid membrane.  ATP synthase uses the flow of hydrogen ions to phosphorylate ADP, converting it to ATP.     The pumping of hydrogen ions into the stroma.  This creates a large difference in concentration and in electric charge between the stroma and the lumen (watery interior) of the thylakoid.  When When the hydrogen ions in the stroma rush back into the thylakoid lumen, they are forced to…
