Suppose that the concentration of Na outside the cell is 100 and inside the cell is 100 mmol/liter. The Nernst equation at 20oC is: You set the membrane voltage at 58 millivolts using a voltage clamp, and measure membrane current. If Na is the only ion crossing the membrane, you would expect to see:

0 current

Explanation:

Given that:

The concentration of Na inside the cell is 100 mmol/liter

The concentration of Na outside the cell is 100 mmol/liter

where;

z(valence of the ionic species for Na⁺ ) = +1, and the membrane voltage is 58 millivolt

Therefore;

answer; i believe the correct answer is (sporophyte);

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
