Homework Answers
The answer is The calvin cycle uses energy stored previously during the light dependent reactions of photosynthesis.
In the light reactions, the sunlight is used make ATP and NADPH which are utilised in the dark cycle to produce sugars.

Chloroplasts that are in the dark do not carry out photosynthesis. The light reactions do not occur to use light energy to make ATP and transfer electrons to NADPH. The Calvin Cycle is then not able to produce sugars from CO2. In an experiment, isolated chloroplasts were first made acidic by soaking them in a solution of pH 4. After the thylakoid space reached ph 4, the chloroplasts were transferred to a basic solution at pH 8. The chloroplasts then...
