Biology Questions and Answers
- What are the chemical
substances produced by water
photolysis? What is the
destination of each of those
substances?
Free electrons, hmolecular oxygen are liberated, afterydrogen ions and (^)
the water photolysis.
The electronselectrons lost by will replace chlorophyll molthose (^) ecules
in photophosphorylation. Tions will be incorporated into hhe hydrogenydrogen
acceptor molecules (NADP) and later
will be used in the synthduring the chemical stage. Molecularesis of glucose
oxygen is liberated to the atmosphere.
- In sulfur photosynthetic
bacteria what is the molecule
that donates hydrogen for
photosynthesis?
In sulfur photosynthetic bacteria thsubstance that donates hydrogen ise
hydrogen sulfide (HTherefore there is no liberation of 2 S) and not water.
molecular oxygen but there is
production o(Oxygen and sulfur have same nf molecular sulfur (Sumber 2 ). (^)
of valence electrons.)
- Why is it said that during
photosynthesis carbon dioxide
is enriched to form glucose?
During photosynthesis carbon dioxide is
energeticallyfrom water. Water b enriched with hroken by photolysisydrogen (^)
is the hydrogen donor of the reaction.
Glucose atoms obtained from carbois made of carbon and oxygn dioxide anden (^)
of hydrogen atoms obtained from water.
- What is the complete
chemical equation of
photosynthesis?
The completphotosynthesis is the following:e chemical equation of
6 CO 2 + 12 H 2 O + light --> C 6 H 12 O 6 +
6 H 2 O + 6 O 2 - What is an example of a
lab experiment that shows the
variation of the
photosynthesis efficiency in
relation to different photic
energy frequencies to which
the reaction is exposed? Was
it expected that green light
frequency favored the
reaction?
The experiment: Plantsand ages are placed each under of same species
(respecting thsources emitting eir photoperiods) lightonly one of the colors (^)
of the light spectrum (violet, anil, blue,
green, yellow ais executed with end red). The experimentach of the colors and
after days each plant's development is
compared. Those plants whosedevelopment was normal performed (^)
satisfactory photosynthesis while those
with abnormal development underusedthe offered light.
