Bio 203 Exam 2 Homework Questions And Correct Answers



If 5 molecules of G3P are to be used to produce one molecule of RuBP, how many ATP
molecules are required in the Calvin Cycle? Answer 3 ATP molecules.



Starting with RuBP how many CO2 molecules are required to make one glucose
molecule?-Answer 6 CO2 molecules, which would yield two G3P molecules that could
combine to make 1 glucose.



After the phosphorylation of 3-PGA, it is reduced by? -Answer: NADPH provides the
electrons for reducing the 3-PGA after phosphorylation.



During carbon fixation, CO2 is added across? -Answer: RuBP



What step ensures the Calvin Cycle can produce a continuous supply of glucose?
-Answer: The regeneration of RuBP is because carbon dioxide is fixed into an organic
molecule that undergoes utilization in producing sugar.



How do the light-dependent and light-independent reactions interrelate? - Answer The
light-dependent reactions produce ATP and NADPH, which are used by the
light-independent reactions.

Light Independent Reaction Biological Importance- What biological significance do the
light-independent reactions of photosynthesis have? - Answer They convert CO2 to
sugar, and all organisms use this sugar to generate energy.



What is the ultimate product of Photosystem I? -Answer NADPH, which would be used to
generate energy in the synthesis of sugars in the process of photosynthesis.



What happens in light-dependent reactions of photosynthesis? -Answer H2O molecules
are cleaved to replace electrons in photosystem II, leaving protons behind to be used
for a gradient to make ATP. Oxygen is produced as a by-product.

, What is the importance of the light-independent reactions for the carbon flux through
the biosphere? - Answer The light-independent reactions transform CO2 gas into an
available carbon form in sugar.



Which, light-dependent or independent reactions use H2O to produce O2? - Answer
Light-dependent reactions



Which of the two processes, cellular respiration or photosynthesis produces oxygen? -
Answer Photosynthesis as a by-product of.



Where is chlorophyll present with regard to the electron transport chain? - Answer Both
of the photosystems I and II.



Which energized electrons enter an electron transport chain and are used to reduce
NADP+? - Answer Photosystem I energized electrons.



What is responsible for splitting water into 1/2 O2, H+, and electron(s)? - Answer
Photosystem II.



What is produced and consumed in the process of moving H+ ions from the stroma into
the thylakoid compartment? - Answer The energy yielded when electrons are shuffled
down the electron transport chain.



The light-dependent reactions of photosynthesis consume ____ and yield ____. - Answer
They consume H2O and generate NADPH.



The Calvin cycle occurs in the _____ of a plant cell. - Answer stroma of the chloroplasts.



What is the immediate source of energy for oxidative phosphorylation? - Answer Kinetic
energy released as H+ ions diffuse down their concentration gradient, the gradient is a
form of potential energy.
