The light reactions provide ATP and NADPH to the carbon fixation
Which statement describes the relationship between the light reactions and the Calvin cycle in photosynthesis?
The light reactions
produce ATP and NADPH
, both of which are used in the Calvin cycle. The light reactions produce ADP and NADP+, both of which are used in the Calvin cycle. The light reactions produce water, ATP, NADPH, all of which are used in the Calvin cycle.
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use
light energy
to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO

.
Which of the following best represents the relationships between the light reactions and the Calvin cycle?
Which of the following statements best represents the relationships between the light reactions and the Calvin cycle? The light reactions provide
ATP and NADPH
to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.
What are the 3 stages of Calvin cycle?
The Calvin cycle reactions can be divided into three main stages:
carbon fixation, reduction, and regeneration of the starting molecule
.
What is the relationship between the light reactions and the Calvin cycle quizlet?
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the
Calvin cycle provides water and electrons to the light reactions
.
What do light reactions supply the Calvin cycle with?
The light reactions produce
carbon dioxide, ATP, NADPH
, all of which are used in the Calvin cycle. The light reactions produce ATP and NADPH, both of which are used in the Calvin cycle.
What best describes the relationship between the two sets of reactions of photosynthesis?
What best describes the relationship between the two sets of reactions of photosynthesis, which are the light-dependent reactions and the light-independent reactions? … During photosynthesis, carbon dioxide and water,
are converted through a series of reactions into two products: high-energy sugars and oxygen gas.
When oxygen is released as a result of photosynthesis?
Terms in this set (20) Where does the Calvin cycle take place? When oxygen is released as a result of photosynthesis, it is a direct by-product of: A:
reducing NADP+
.
What are the two major outputs of the light reaction used in the Calvin cycle?
Outputs of the light reactions are oxygen, which is released to the atmosphere, and ATP and NADPH, which go into the Calvin cycle. Outputs of the Calvin cycle are
ADP, P, and NADP
+
, which go into the light reactions, and sugar, which is used by the plant. 2.
Is CO2 oxidized or reduced in the Calvin cycle?
Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the
overall reduction
of CO2, using the electrons available from the oxidation of NADPH. … NADPH is oxidized to NADP+ and CO2 is reduced to glucose.
What is the primary function of the Calvin cycle?
The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for
energy and food
.
How does Calvin cycle begin?
In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3,
RuBP
, the molecule that starts the cycle, is regenerated so that the cycle can continue. In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO
2
.
Does the Calvin cycle release oxygen?
The Calvin Cycle converts three water and three carbon dioxide molecules into one molecule of glyceraldehyde. The
six left over oxygen atoms are released into the atmosphere
where they are available for use in respiration.
What is the most important result of the Calvin cycle?
What is the most important result of the Calvin Cycle?
The ‘fixing' of CO2 to yield two molecules of PGAL
. … The reations of photosynthesis that convert carbon dioxide from the atmosphere into carbohydrates using the energy and reducing power of ATP and NADPH.
Which products of the Calvin cycle are used by the light Reaction quizlet?
What are the products of light reactions and how are they used? The products are
ATP and NADPH, and oxygen
. ATP and NADPH supply energy for carbon fixation in the Calvin cycle . Oxygen is released into the atmosphere.
