To identify the molecule that accepts 
, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The acceptor concentration would increase when the 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 or removing light from cultures of photosynthetic algae in order to find the molecule that takes . Following the alteration, they evaluated the concentrations of several metabolites.

<span>Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen. When enough proteins have been synthesized, they collect and are pinched off in vesicles.</span>
The major evolutionary episode corresponding most closely in time with the formation of Pangaea was the Permian Extinctions.
The Permian Extinctions happened around 300 million years ago and lasted for around 15 million years. It eliminated over 95 percent of water life and 70 percent of species on land. It was one of the largest extinctions in the history of Earth.
