LIGHT DEPENDENT REACTIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does the Calvin cycle differ from the light-dependent reactions? It ____
A
requires light
B
takes place in the stroma
C
takes place in the grana
D
takes place in the chloroplasts
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The light-dependent reactions release oxygen as a byproduct as water is broken apart. In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.

Detailed explanation-3: –The purpose of the light-dependent reactions is to use water and light to produce ATP and NADPH or energy that the cell can use.-The Calvin Cycle uses the energy produced in ATP and NADPH to produce glucose.

Detailed explanation-4: -The light-independent reactions release energy, and the light-dependent reactions require energy. The light-dependent reactions pass electrons through an electron transport chain to the light-independent reactions.

Detailed explanation-5: -What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
