Question
Chapter 8.4, Problem 2EQ
Summary Introduction
To determine: The use of 14C labelled CO2 in the experiment of the Calvin cycle.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that uses the energy from the light-dependent reactions. It then employs the energy (ATP and NADPH) to synthesize carbohydrates that can be further used by the plant.
Summary Introduction
To determine: The results of the examination of the samples taken from the Calvin cycle at different times.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that was discovered by Melvin Calvin, Andrew Benson and their colleagues. The cycle uses energy from the light-dependent reactions.
Summary Introduction
To determine: The method by which different samples were identified in the experiment.

Q. 16
Please answer correctly well explained and not from google internet.
The first researchers who worked on the process of photosynthesis had difficulty finding the enzyme that performed the fixation of carbon dioxide, because they were looking for an enzyme that could attach CO2 to a two-carbon compound.
Explain why these researchers were looking for a two-carbon compound.
WHAT IF? The Calvin cycle requires ATP and NADPH,products of the light reactions. If a classmate assertedthat the light reactions don’t depend on the Calvin cycleand, with continual light, could just keep on producingATP and NADPH, how would you respond?
Please explain thoroughly. Thanks.
