Which of the following identifies the function of glycolysis within the entire process of cellular respiration?
breaks down glucose into two pyruvate molecules
reforms nad+ and fad to reuse in other parts of respiration
sends energy-rich molecules to electron transport chain
converts adp to atp for use as cellular energy

The correct answer is- Breaks down glucose into two pyruvate molecules.

Glycolysis is a metabolic process in which glucose is broken down into two molecules of pyruvate ( 3 carbon molecule) with the release of net 2 ATP and 2NADH molecules.

It occurs in cytoplasm the cell and it is the first phase of cellular respiration.

Glucose is one of the most significant source of energy for living organisms. Thus, through glycolysis, energy is extracted and utilized by the cell.

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.
