Answer: Time required for 100 molecules of valinomycin to transport enough $K^{+}$ to change the concentration inside an erythrocyte is 10 minutes.

Explanation:

The given data is as follows.

Ions to be transported = $(10 mM) \times (100 \mu^{3})(N)$

= $0.010 mol \times 10^{-13} L \times 6.02 \times 10^{23} ions/mol$

= $6.02 \times 10^{6}$ ions

Here, there are 100 ionophores are present and each one of ionophores are required to transport a value of ions.

Therefore, the time required for 100 molecules of valinomycin to transport enough $K^{+}$ to change the concentration inside an erythrocyte is as follows.

$6.02 \times 10^{6} ions \times \frac{1 sec}{10^{4} ions}$

= 602 sec

or, = 10 minutes (as 1 min = 60 sec)

Thus, we can conclude that time required for 100 molecules of valinomycin to transport enough $K^{+}$ to change the concentration inside an erythrocyte is 10 minutes.

What has to happen for a feather and a ball to fall at the same rate

Digiron [165]

If the ball is dropped from a higher height than the feather their rates of displacement (acceleration) could match.
