Use the Pyruvate Concentration Table to answer the question. The researcher adds a chemical to the cytosol at the one-hour mark. The full effect of the chemical can be observed at the two-hour mark. Which of the following hypotheses regarding the effect of the chemical is MOST reasonable?

A.
The chemical inhibits the carrier protein for pyruvate in the mitochondrial inner membrane.

B.
The chemical inhibits the carrier protein for glucose in the plasma membrane.

C.
The chemical inhibits the carrier protein for glucose in the mitochondrial inner membrane.

D.
The chemical inhibits the protein channels in the mitochondrial outer membrane.

The Answer is A. the chemical inhibits the carrier potein for pyruvate in the mitochondrial inner membrane.

Explanation:

I just took the test so I know this is right

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.
