What are the products of light-dependent reactions and why are they important in light-independent reactions?

-The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.

What are the products of light-dependent reactions Why are they important in light-independent reactions quizlet?

The Light-Independent uses ATP and NADPH from the Light-Dependent reactions to produce high energy carbohydrates and oxygen.

What are the products of light-dependent and light-independent reactions?

Reading: Light-Independent Reactions The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years.

What is the purpose of the light independent reaction?

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 is required for light reactions to occur?

The reactants of photosynthesis are carbon dioxide and water. These are the molecules necessary to begin the process. But one more item is necessary, and that is sunlight. All three components, carbon dioxide, water, and the sun’s energy are necessary for photosynthesis to occur.

What is the difference between light reaction and dark reaction?

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.

Which of the following is the main function of the light dependent 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 produced in the light dependent reaction and used in the Calvin cycle?

Overview of the Calvin cycle This process is fueled by, and dependent on, ATP and NADPH from the light reactions. This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Where does water in the light dependent reaction come from?

The light-dependent reactions begin in photosystem II. In PSII, energy from sunlight is used to split water, which releases two electrons, two hydrogen atoms, and one oxygen atom.

Does light dependent reaction require sunlight?

Just as the name implies, light-dependent reactions require sunlight. 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 CO2.
