Light Reactions
Input: H₂O, Light
Output: O₂, ATP, NADPH
Here, Light energy and water is utilized to create ATP and NADPH which will go into the Calvin Cycle and power it to create sugar the plant can use as food.

Calvin Cycle
Input: CO₂, ATP, NADPH
Output: Glyceraldehyde 3-phosphate [G3P]
This is an anabolic action that uses ATP’s energy and NADPH’s reducing power [gain of electrons, storage of energy] to build sugar. Carbon dioxide enters the cycle and is fixated by the enzyme rubisco, then reduction occurs as the carbon dioxide becomes sugar. But, this must occur three times for one G3P to be formed. So, once carbon dioxide is fixated and reduced,the CO₂ acceptor RuBP is regenerated so that the next carbon dioxide entering the cycle can be fixated. Once this process occurs thrice, a sugar [G3P] is created.

p.s. It's not called the 'Calvin Klein Cycle'. It's just Calvin.
