The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions. The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II.

What are the 3 products produce during light reaction?
The Light Reactions The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced.
What are the products of the light-dependent reactions quizlet?
The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH.
Which of the following are two products of the light-dependent reactions quizlet?
PGAL and PGAL. Glucose is actually formed in photosynthesis when two molecules are joined together. These two molecules are? NADPH is produced during the light dependent reaction of photosynthesis.
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 produced during the light reaction quizlet?
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 are the light independent products?
The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.
What is the input and output of the light-dependent reactions?
Light-dependent reactions convert solar energy into chemical energy in the form of NADPH and ATP. the input molecules are carbon dioxide and the output molecules are sugar, ADP, NADP+, and inorganic phosphate.
What are the 2 products of the light reactions that are used in the Calvin cycle?
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
What is the product of the light reaction of photosynthesis?
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
What are light-independent reactions quizlet?
The light-independent reaction: The second and final stage of photosynthesis. It uses the products of the light-dependent reaction (ATP and reduced NADP) to make organic substances for the plant.
What is the function of the light-dependent reactions?
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 produces ATP and NADPH?
Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.
What happens during the light dependent reaction 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.
Which molecule is produced during the light reactions?
What two molecules are produced by the light reactions and used to power the Calvin cycle? ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.
What is the final product of the light-independent reactions?
The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
What are produced at the end of light independent reaction?
After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build carbohydrate molecules.
What are the important events and end products of light reaction?
Answer: The important events of light reaction are (i) Excitation of chlorophyll molecule to emit a pair of electrons and use of their energy in the formation of ATP from ADP + Pi. This process is called photophosphorylation. Splitting of water molecule (a) (b) End products of light reaction are NADPH and ATP.
What is the two product of light reaction?
There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions.
Which best lists the end products of the light-dependent reactions of photosynthesis?
Which best list the end products of the light dependent reactions of photosynthesis? ATP, NADPH, and 02.
What are the 3 products of the light reactions 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.
Where do light-dependent reactions occur quizlet?
Light dependent reaction occurs in the thylakoid membranes of the chloroplast.
What are the roles of ATP and NADPH in photosynthesis quizlet?
What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy; in the case of NADPH, it has reducing power that is used to fuel the process of making carbohydrate molecules in light-independent reactions. Which of the following statements is true?
Which process occurs during the light dependent reaction of photosynthesis quizlet?
Which process occurs during the light-dependent reactions in photosynthesis? Water molecules are split.
How many ATP are produced in light-dependent reactions?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
