Glucose
No, glucose is not a direct result of the light reactions of photosynthesis. The light reactions, which occur in the thylakoid membranes of chloroplasts, convert light energy into chemical energy in the form of ATP and NADPH. Glucose is produced during the Calvin cycle, which is the second stage of photosynthesis that occurs in the stroma of chloroplasts, using the ATP and NADPH generated from the light reactions to fix carbon dioxide.
The product of the light reactions of photosynthesis is ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules provide the energy necessary for the Calvin cycle (dark reactions) to produce glucose.
The initial reactions in photosynthesis are known as the light-dependent reactions. These reactions occur in the thylakoid membranes of the chloroplast and involve the absorption of light energy to drive the conversion of water into oxygen, ATP, and NADPH.
The two major sets of reactions involved in photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to produce ATP and NADPH, while in the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
light dependant reactions
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.

The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
There are two reactions. Those are light dependent and independent.
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
The Calvin cycle does not require light, these reactions are also called the Light Independent reactions.
