Answer:
because the Calvin cycle requires the products from light dependent reaction in order to proceeds.
Step-by-step explanation:
The Calvin cycle is one of the two stages of photosynthesis. It is also commonly referred to as light-independent reaction.
During photosynthesis, the light dependent reaction generates ATP and NADPH from the photolysis of water. Thereafter, the ATP and NADPH generated are utilized in Calvin cycle to fix carbon dioxide to generate glucose.
It thus means that if the light dependent reaction is hindered, there will not be ATP and NADH available to drive the Calvin cycle. Hence, the so called light-independent reaction indirectly depends on the light dependent reaction.
Therefore, it is not entirely accurate to adopt the phrase 'light-independent reaction' when referring to the Calvin cycle because the Calvin cycle requires the products from light dependent reaction in order to proceeds.
