Photosynthesis is the process
by which plants capture light energy and use it to produce their own organic compounds
by which bacteria capture glucose and use it to produce energy
by which animals produce energy
that only occurs in prokaryotic organisms
Photosynthesis occurs in
mitochondria
ribosomes
the golgi apparatus
chloroplasts
the light-dependent stage of photosynthesis occurs in the
cristae
thylakoid membrane
stroma
chlorophyll
ATP is produced during the light-dependent stage. What is this ATP used for?
it is a waste product and not used for anything
to split water
to provide the energy needed for the light-independent stage
to absorb the light energy required for photosynthesis
A major product of photosynthesis is
carbon dioxide
ATP
NADPH
glucose
At which stage of photosynthesis is oxygen released as a by-product?
The light-independent stage
The light-dependent stage
During the Calvin cycle
During Krebs cycle
ATP is the universal source of free energy for all living organisms. It is composed of adenine and ribose with how many phosphate groups attached?
1
2
3
4
requires energy
is irreversible
provides the energy needed to drive cellular processes
only occurs in prokaryotes
In periods of high light intensity, the rate of photosynthesis will
increase indefinitely
increase until another factor like carbon dioxide becomes limiting
decrease indefinitely
decrease until another factor such as carbon dioxide becomes limiting
Rubisco is the enzyme that enables carbon dioxide to join with the 5C intermediate Ribulose biphosphate in order to continue through the metabolic pathway that produces glucose.
It would be expected that rubisco is found in high concentrations in the
cytoplasm
matrix
stroma
thylakoid
Chloroplasts
contain glycogen
are found in all plant cells
are found in some bacterial cells
contain layers of internal membranes
The chloroplast is the organelle responsible for photosynthesis in eukaryotic cells. In chloroplasts
the light independent reactions require water as the initial reactant
the light independent reactions occur in the inner membrane area
the final product of the light reaction is glucose
the light reactions occur in the grana
the rate of the light independent reactiosn on the thylakoid membranes of the chloroplasts increases
water loss from the leaf decreases, resulting the availability of water for photosynthesis increasing
Which of the following statements about photosynthesis in the chloroplasts is correct?
The grana are the site of the light-independent stage
Chlorophyll found in the stroma traps light for use during the light-dependent stage
The light-dependent stage produces ATP for the light-independent stage
The light-independent stage captures carbon dioxide for use during the light-dependent stage to produce glycose
What is/are the products of light independent reaction?
ATP
NADPH
H₂O
C₆H₁₂O₆
pyruvate
What is NOT the product of light dependent reaction?
ATP
NADPH
H₂O
O₂

RuBP (Ribulose bisphosphate)
RuBisCo (Ribulose Bisphosphate Carboxylase)
PGA (3-Phosphoglycerate)
G3P (Glyceraldeyhyde 3-Phosphate)
H₂O and O₂
electrons and H+
ATP and NADPH
