What is the raw material used for light reactions of photosynthesis?

The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.

What are needed in the light phase of photosynthesis?

During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.

What are the materials needed in light reaction?

Co2, water, chlorophyll, and sunlight are four important requirements for this process. Photosynthesis occurs in two steps: Light reaction and Dark Reaction.

Which raw material of photosynthesis is used in Calvin cycle?

The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

What is the raw materials of light independent reaction?

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 are the raw materials needed and products created in the Calvin cycle dark reaction )?

During the Calvin cycle of photosynthesis, the plant uses carbon dioxide with the ATP and NADPH from the light-dependent reactions to produce glucose.

What raw materials are needed for the dark reactions?

This phase is called the dark reaction, since light is not required for the process to proceed. In the dark reaction, carbon and oxygen from the carbon dioxide molecule, along with the hydrogen left over from the light reaction, combine (in a series of complex reactions) to form glucose, a simple sugar.

What are the raw materials of dark reactions?

What is a dark reaction? In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose. It takes place in the stroma of the chloroplast.

Why does Calvin cycle need products of 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.

What are the two products of the light reactions that are needed for the Calvin cycle?

ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.

What is required for the Calvin cycle to occur?

All three necessary conditions are required – chlorophyll pigments, the chloroplast “theater,” and enzyme catalysts. The first stage transforms light energy into chemical energy, stored to this point in molecules of ATP and NADPH.

What is light independent in 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 are the requirements of light-independent reactions?

The requirements or ingredients for light-independent reactions are carbon dioxide and energy in the form of ATP and NADPH.

How does light phase differ from Calvin cycle?

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.

What is required for both the light-dependent and light-independent reactions to proceed?

Light dependent reactions occur in Grana of Chloroplasts, Light Independent reactions occur in Stroma of Chloroplasts. Hence Chloroplasts are required for both the light-dependent and light-independent reactions to proceed. Elaine C. The answer is energy.

Do light-independent reactions require sunlight?

The light-independent reaction uses the electrons from the light-dependent reactions to energize the process, particularly during the conversion of inorganic compounds into organic compounds, such as carbohydrates. They do not require light or energy from the sun to initiate the reaction.

What is the main product of the light-dependent reactions of photosynthesis?

The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.

What is required for both the light-dependent and light-independent reactions to proceed quizlet?

ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions. … The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

What are the products of light-independent reactions quizlet?

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

What two reactants do light-independent reactions need?

This dependency comes from the required reactants ATP and NADPH, which are quickly used up by the Calvin cycle reactions.

What process occurs during the light-independent reactions of photosynthesis 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.
