What happens during the light-dependent reactions of photosynthesis?
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
What happens during the light-dependent reactions of photosynthesis quizlet?
What happens during the light-dependent reactions? The light-dependent reactions use energy from sunlight to produce oxygen and convert ADP and NADP+ into the energy carriers ATP and NADPH. These reactions also produce oxygen as a by-product.
What happens during 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.
What are the steps in the light-dependent reactions?
These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.
Which of the following events occurs in the light reactions of photosynthesis?
The events occurring in the light reaction of the photosynthesis are: Absorption of sunlight by the chlorophyll and release of the electron to the carriers. Photolysis of water to provide the electron to the chlorophyll. The release of molecular oxygen due to the photolysis of water.
What is a 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.
What is the purpose of the light-dependent reactions of photosynthesis quizlet?
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP.
What happens during the light-dependent and independent reactions of photosynthesis?
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 light-dependent reaction quizlet?
Light-Dependent Reactions. Require light to grow, it also use energy from light to produce oxygen gas and convert ADP and NADP into energy carriers ATP and NADPH.
Which of the following occurs during the light-dependent reactions of plants?
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.
What is the main purpose of the light-dependent reactions?
-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 three events occur during the light reactions of photosynthesis quizlet?
The correct sequence of events in the light reactions is… absorption of sunlight, splitting of water, electrons flow down the electron transport chain, and ATP is made.
Where do the light-dependent reactions of photosynthesis occur quizlet?
The light-dependent reactions take place on the thylakoid membranes (the light is absorbed by the chlorophyll that is embedded in these membranes). The light-independent reactions (also called the Calvin Cycle or the dark reactions) take place in the stroma. The stroma is the fluid that fills the chloroplast.
What is the function of the light-dependent reactions?
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 steps of the light-dependent reactions?
Here are the basic steps:
- Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. …
- ATP synthesis. …
- Light absorption in PSI. …
- NADPH formation.

Which of the following occurs during the light reactions of photosynthesis quizlet?
– The light reactions take place inside the thylakoids of chloroplasts. – The light reactions produce chemical energy in the form of NADPH and ATP.

What are 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.
Which of the following occurs during the light-independent reactions of photosynthesis?
2) Calvin cycle, light independent reaction. Takes place on the stroma, inside the chloroplast. There are many enzymes in the chloroplast that aid to form starch by photosynthesis. The energy stored is transferred to the stroma and with the other raw materials chains of carbohydrate molecules are produced.
Which of the following occurs during the light-dependent reactions quizlet?
Which of the following occurs during the light-dependent reactions of plants? Light-driven electron transport in the chloroplast pumps H+ into the intermembrane space between the outer and inner membranes.
What happens during the light-dependent reactions and during the light-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.
Which of the following events occurs in the light reactions of photosynthesis quizlet?
Which of the following events occurs in the light reactions of photosynthesis? Light is absorbed and funneled to reaction-center chlorophyll a.
Which of the following occurs in the light-dependent reactions?
Which of the following occurs during the light-dependent reactions of plants? Light-driven electron transport in the chloroplast pumps H+ into the intermembrane space between the outer and inner membranes.
Where do light-dependent reactions occur in photosynthesis?
The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.
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.
