If a membrane protein in an animal cell is involved in the cotransport of glucose and sodium ions into the cell, which of the following is most likely true?

a) the sodium ions are moving down their electrochemical gradient while glucose is moving up.
b) glucose is entering the cell along its concentration gradient.

c) sodium ions can move down their electrochemical gradient through the cotransporter whether or not glucose is present outside the cell.
d) potassium ions move across the same gradient as sodium ions.
e) a substance that blocked sodium ions from binding to the cotransport protein would also block the transport of glucose.

The correct answer is E) A substance that blocked sodium ions from binding to the cotransport protein would also block the transport of glucose.

Explanation:

Cotransport means that one molecule is being transported through the membrane while another molecule is transported with that energy by the same transporter. Therefore if one substance is blocking the sodium ions from binding to the protein, therefore the glucose couldn't be transported either.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

i don't know why i put this, i know its not the i was just bored : p
