What is the significance of the light-independent reactions?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast's own genetic material (separate from that of the cell) is also stored in the stroma.
What is the biological significance of the light-independent reactions dark reaction of photosynthesis?
The main purpose of the light reaction is to generate organic energy molecules such as ATP and NADPH which are needed for the subsequent dark reaction. Chlorophyll absorbs the red and blue segment of the white light and photosynthesis occurs most efficiently at these wavelengths.
What is the purpose of light-dependent and independent reactions?
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.
What is the main purpose of light-dependent reactions of photosynthesis quizlet?
-The purpose of the light-dependent reactions is to use water and light to produce ATP and NADPH or energy that the cell can use.
What is the overall purpose of the light reactions in photosynthesis?
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.
What are the three major light-independent reactions in photosynthesis?
The light-independent reactions (also known as the Calvin cycle) can be organized into three basic stages: fixation, reduction, and regeneration (Video 13.6. 1).
What is the role of light reaction of photosynthesis?
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.
What is the importance of the light and dark reactions in photosynthesis?
What is the importance of the light and dark reactions in photosynthesis? During the light reactions of photosynthesis, light energy from the sun is captured and used to make ATP and NADPH. During the dark reactions, ATP, NADPH, and carbon dioxide combine to make glucose and other compounds.
What happens during the light dependent and light-independent reactions of photosynthesis?

Which purpose is the main function of the light Dependant reactions of photosynthesis?
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.
What is the biological significance of the Calvin cycle reactions of photosynthesis?
The function of the Calvin cycle is to create three-carbon sugars, which can then be used to build other sugars such as glucose, starch, and cellulose that is used by plants as a structural building material. The Calvin cycle takes molecules of carbon straight out of the air and turns them into plant matter.
What is the main purpose of the light-dependent reactions Quizizz?
Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane. Light causes the conversion of water into carbon dioxide, oxygen, and electrons.
Which best describe light-independent reactions?
Which best describes light-independent reactions? They are the first stage of photosynthesis. They utilize the energy stored in ATP and NADPH.
What is the importance of the light reactions of photosynthesis since they do not directly produce energy rich carbohydrates?
What is the importance of the light reactions of photosynthesis since they do not directly produce energy-rich carbohydrates? They produce ATP and NADPH that are used by the carbon cycle.
How are the light reactions of photosynthesis important to the production of glucose?
Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced.
What is the importance of the light reactions of photosynthesis since they do not directly produce energy-rich carbohydrates?
What is the importance of the light reactions of photosynthesis since they do not directly produce energy-rich carbohydrates? They produce ATP and NADPH that are used by the carbon cycle.
Why is it important in photosynthesis that there is a light and dark reaction What are the key features of these processes and how do they interact with each other?
What is the importance of the light and dark reactions in photosynthesis? During the light reactions of photosynthesis, light energy from the sun is captured and used to make ATP and NADPH. During the dark reactions, ATP, NADPH, and carbon dioxide combine to make glucose and other compounds.
What is the light independent stage of photosynthesis?
The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.
What is the purpose of the light-dependent reactions of photosynthesis?
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.
What are the products of the light dependent reaction in photosynthesis Quizizz?
form oxygen, water, NADPH, and glucose. pump hydrogen ions into the stroma, producing a concentration gradient that will later be used by an enzyme to form ADP and phosphate.
Which substance from the light-dependent reactions of photosynthesis is a source of energy for the light independent reactions Quizizz?
ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy. Q.
Where do light-independent reactions occur during photosynthesis?
Photosynthesis occurs in the chloroplasts, the light-dependent reactions are located on the innermost membrane of chloroplasts called thylakoid membrane and light-independent reactions occur in the cytoplasm of the chloroplasts called stroma (17).
What is the importance of light in photosynthesis?
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
Why is it important for plants to have light independent dark reactions?
While sunlight is used during the light reactions to produce ATP and the electron carrier NADPH, the dark reactions use these products to complete photosynthesis without the use of light energy. The light reactions produce ATP and NADPH in the thylakoids of chloroplasts.
What is the purpose of light reactions?
Explanation: The light reactions are the steps of the photosynthesis that function to convert solar energy into chemical energy that can be used during the Calvin cycle. The light reactions use solar energy to reduce to and to convert to .
What is the main purpose of light-dependent reactions Quizizz?
Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane. Light causes the conversion of water into carbon dioxide, oxygen, and electrons.
