Exam-bio 1108 Exam 2 (Herrick)Questions withComplete Solutions 100% Pass
photosynthesis CORRECT ANS-biochemical process for building carbohydrates using energy
from sunlight and carbon dioxide taken from the air
what is the photosynthesis equation? CORRECT ANS-CO2 + H2O ---> C6H12O6 + CO2
reduction (in photosynthesis) CORRECT ANS-molecules acquires electrons and gains
energy
oxidation CORRECT ANS-molecules loses electrons and releases energy
what is being reduced in the photosynthesis equation? CORRECT ANS-CO2 ---> C6H12O6
what is being oxidized in the photosynthesis equation? CORRECT ANS-H2O ---> O2
who is the electron donor? CORRECT ANS-water; oxygen is transformed as a by product

photosynthetic electron transport chain CORRECT ANS-series of reactions that links
oxidation of water to reduction of carbon dioxide
where is the electron transport chain located? CORRECT ANS-the thylakoid membrane
where does the light cycle occur? CORRECT ANS-the grana
calvin cycle CORRECT ANS-sugars are synthesized from CO2
calvin cycle requires: CORRECT ANS-two molecules of NADH and three molecules of ATP
for each CO2 incorporated into carbohydrates
steps of the Calvin cycle CORRECT ANS-1. carboxylation
2. reduction
3. regeneration

carboxylation CORRECT ANS-CO2 +(rubisco)+ RuBP = 2(3-PGA)
-the addition of CO2 to the 5-carbon compound RuBP
rubisco CORRECT ANS-catalyzes carboxylation reaction which originally would take a long
time
reduction (in Calvin cycle) CORRECT ANS-3-PGA---(ATP and NAPH)----> triode phosphate
-NADPH transfers two electrons and one proton; inorganic phosphate is released
regeneration CORRECT ANS-triose phosphate -------(ATP)----> RuBP ---> beginning of cycle
-(regeneration of RuBP) a multistep process where 3-carbon compounds are reorganized and
combined to produce RuBP

light reaction CORRECT ANS-water is broken apart in the chlorophyll molecule into H+ and
OH- ions in the presence of light, resulting in the formation of NADPH and ATP
photosystems CORRECT ANS-PSI and PSII; protein-pigmented complexes; the functional
and structural unit that absorbs light energy and uses it to drive electron transport
chlorophyll light absorption CORRECT ANS-z-scheme; absorption of visible light by an
antenna chlorophyll results in the transfer of energy to an electron in a neighboring
chlorophyll molecule
reaction center CORRECT ANS-configured pair of chlorophyll molecules where energy is
transfered to, then converted to chemical energy (from antennae chlorophyll)
PSII CORRECT ANS-energizes electrons to the beginning go the electron transport chain;
when it loses an electron, it is able to pull electrons from water
PSI CORRECT ANS-energizes electrons with a second input of light energy so that they can
be used to reduce NADP+
