LIGHT DEPENDENT REACTIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Produces glucose. Light independent or light dependent stage?
A
Light independent stage
B
Light dependent stage
Explanation: 

Detailed explanation-1: -The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 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.

Detailed explanation-2: -What the products of the light independent reactions? Explanation: The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.

Detailed explanation-3: -Photosynthesis, a fundamental light-dependent reaction in plants that takes in carbon dioxide from the air, along with water, and light to produce glucose as a source for plant growth. The C6H12O6 is the glucose. This reaction requires light for it to proceed.

Detailed explanation-4: -Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.

Detailed explanation-5: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
