To identify the molecule that accepts $CO_{2}$ , Calvin and Benson manipulated the carbon-fixation cycle by either cutting off $CO_{2}$ or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The $CO_{2}$ acceptor concentration would increase when the $CO_{2}$ is cut off, but decrease when the light is cut off.

The correct option is d.

The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.

Calvin and Benson disrupted the carbon-fixation cycle by either removing $CO_{2}$ or removing light from cultures of photosynthetic algae in order to find the molecule that takes $CO_{2}$ . Following the alteration, they evaluated the concentrations of several metabolites.
