Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts) . This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
How does the Calvin cycle differ from the light-dependent reactions quizlet?
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma. The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions. During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.
How does the Calvin cycle dark reactions differ from the light-dependent reactions?
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma . The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions. During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.
How are light reactions and the Calvin cycle similar?
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.
How does light affect the Calvin cycle?
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 is the difference between light-dependent reaction and light-independent reaction?
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
Does the Calvin cycle require light?
The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.
Where does the light-dependent reaction take place quizlet?
In photosynthesis, the light-dependent reactions take place on the thylakoid membranes . The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
How does the Calvin cycle work?
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase . Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
What is the difference between the light reactions and dark reactions?
The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light ...
What is the difference between light and dark?
Light exists in many wavelengths we cannot see, but those wavelengths do not constitute ‘darkness' . Something that appears dark in visible light might be giving off light in a wavelength we cannot see. True darkness is the absence of all light, it cannot be transmitted or otherwise moved.
What are the differences between light phase and dark phase?
Answer: Dark reaction takes place with the presence or absence of sunlight. Light reaction is considered as the light dependent reaction . Light reaction is also called as photo-chemical phase.
What is the difference between the light and dark cycle of photosynthesis?
The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light ...
Why is the light reaction and Calvin cycle dependent on each other?
The light dependent reaction of photosynthesis provides two important requirements ATP and NADPH to the Calvin Cycle . ATP-It is a energy rich compound. The light energy is stored in it. It provides the energy for the formation of energy rich chemical bonds in glucose.
Why are the light-dependent reactions important to the Calvin cycle?
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy . This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
How do the light reactions help the Calvin cycle work together to build glucose?
How does the light reactions and Calvin cycle work together to build glucose? The Calvin Cycle uses the NADPH and ATP from the Light Reactions to “fix” carbon and produce glucose . Carbon dioxide enters the Calvin Cycle when Rubisco attaches it to a 5-carbon sugar.
What are the differences between the light-dependent reactions and the light-independent reactions quizlet?
The light-dependent reactions require light and water, occur in the thylakoids, and produce ATP and NADPH. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars.
Which of the following is an important difference between the light dependent and the light independent dark reactions of photosynthesis?
What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH , whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
Why is the Calvin cycle referred to as a dark reaction?
Only the light reaction directly uses light. The Calvin cycle is fueled by products from the light reaction, but doesn't need light . Therefore it is called the dark reaction.
Where does light reaction occur?
The light reaction takes place in the thylakoid discs . There, water (H 2 0) is oxidized, and oxygen (O 2 ) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
What are the products of light reactions that are used in the Calvin cycle?
ATP and NADPH produced by the light reactions are used by the Calvin cycle to make carbohydrates.
Where does the Calvin cycle take place?
Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts) .
What does the light dependent reaction use?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
How do you define light-dependent reactions quizlet?
light dependent reactions. reactions of photosynthesis that use energy from light and water to produce ATP and oxygen that is released into the atmosphere .
