50 POINTS I NEED THIS ANSWERED IMMEDIATELY Describe the overall changes in matter that occur during the light-independent reactions. What does the plant start with and what does it end with? What is the source of energy that powers this change?

There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is called the "dark reaction", the Calvin cycle does not actually occur in the dark or during nighttime.

The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
