• Pasteur Effect, Glucose, Photosystem, and Other Short Answer Questions

  Explain this Pasteur effect. 2) If a plant is kept for many days in the dark, glucose is not produced, even though the sugar producing reactions are called light-independent. Why is glucose not produced in this case?

• Experiment

  The second part of the reaction, called the dark reaction, make use of the carbon dioxide and the remaining hydrogen atoms left from the light reactions to make up the glucose.

• Photosynthesis and Cellular respiration description

  The light reactions occur in the grana of the chloroplast. DARK OR LIGHT INDEPENDENT REACTIONS NADPH is used in the light independent reactions to form macromolecules. This is also called the Calvin Cycle.

• Effect of Light Intensity on Photosynthesis: Lab Experiment

  Because the reactions in the second stage do not require the direct use of light energy, they are called the dark reactions of photosynthesis.

• Light-Dependent Reactions

  Water molecules are oxidized during the Light-Dependent Reactions and oxygen gas is released. 2. ATP and NADPH enter the Light-Independent Reactions. These reactions take place in the stroma of the chloroplast.

• Photosynthesis

  However, many students believe (incorrectly) that the dark reactions can occur in the dark. No, not so! The dark reactions are better known as "light-independent" reactions.

• DNP & Photosynthesis in plants

  NADPH will still be synthesized as a result of this process. However, since ATP is no longer being produced, the light-independent reactions (the "dark" reactions) will come to a standstill. How come?

• Structure and Function of ATP

  It is a light independent process in which the products of the light reaction (i.e., ATPs) are used to form carbon-carbon covalent bonds of carbohydrates. During this process ATP formed during light reaction are utilized.

• Photosynthetic reactions

  The dark reaction involves a cycle called the Calvin cycle in which CO2 and energy from ATP are used to form sugar. For complete answer and references, please see the attached file.
