19. Part 1: Sequence analysis: Arrange the sequence of events from
start to finish in the process of photosynthesis.
The photon is absorbed by the chlorophyll
receptors in the PSII, causing the excitation
of the unenergized electrons.
Energized electrons will pumped
out of the PSII and be transferred
in the Electron Transport Chain.
Electrons are being replaced in the
PSII by splitting water molecules into
hydrogen and oxygen ions.
Hydrogen are forced to go inside the thylakoid
as the electrons passes through the ETC,
making Concentration Gradient of Hydrogen ion
in the Thylakoid.
Through chemiosmosis, ATP synthase will
pump out hydrogen ion which will generate
ATP by adding phosphate in ADP
Electrons in the Primary ETC will lose energy
as they reach PSI. It will regain energy in the
P700 and soon be pumped out the PSI
Energized Electrons in the PSI will
phosphorylate NADP+ through ferredoxin
to become NADPH
RuBP is a 5 carbon molecule which
attaches to a carbon of CO2 which
quickly breakdown to form 3PGA.
3PGA undergoes reduction
process by converting it to
BPA using ATP and to G3P
using NADPH.
The Calvin cycle needs to run
twice to produce 1 molecule of
Glucose.
