Calvin cycle is the term which is used for the process by which the light reactions of photosynthesis produce energy in the form of Adenine tri phosphate (ATP).
Explanation:
Calvin cycle is an important phase of photosynthesis which consists of two stages. In the first stage, ATP and NADPH are produced from chemical energy in the presence of sunlight. In the second stage, water and carbondioxide combines with each other forming glucose molecule.
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
Answer: A) Physical Change because even though color change occurred, each solid maintained its original properties which you could see as soon as the magnet was applied .
