The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO 2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.

In the light-dependent reactions of photosynthesis, the energy from light propels the electrons from a photosystem into a high-energy state. In plants, there are two photosystems , aptly named Photosystem I and Photosystem II, located in the thylakoid membrane of the chloroplast .
Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP.
Nov 9, 2024 · The purpose of the light-dependent reactions is to convert light energy into chemical energy in the form of ATP and reduced NADP (NADPH). ATP serves as the energy currency of the cell, while NADPH provides the reducing power needed for the synthesis of glucose in the Calvin cycle. Both products are essential for driving the next phase of ...
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
