Which is a product of the light reaction?

NADPH and ATP

Explanation:

The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
