To examine: Whether the statement, “Transport by transporters can be either active or passive, whereas transport by channels is always passive” is true or false. Concept introduction: In the cell membrane, transporter conducts both active and passive transport. Both the transport system allows the cell to maintain homeostasis by sustaining equilibrium of the molecules inner and outer side of the cell. They both are mediated by membrane transport protein.

Answer 1

Question

Chapter 11, Problem 1P

Summary Introduction

To examine: Whether the statement, “Transport by transporters can be either active or passive, whereas transport by channels is always passive” is true or false.

Concept introduction:

In the cell membrane, transporter conducts both active and passive transport. Both the transport system allows the cell to maintain homeostasis by sustaining equilibrium of the molecules inner and outer side of the cell. They both are mediated by membrane transport protein.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is true.

Explanation of Solution

Transporters attach with specific molecules that undergoes spontaneous conformational changes. These conformational changes carry the molecule across the cell membrane to facilitate transport. The molecules can transport passively down the electrochemical gradient.

On the other hand, the channels create aqueous pores through which molecules travel depending on the concentration gradient. In this case, the transportation of molecules is always in downhill movement, which is the passive movement of molecules. They interact with the solutes weakly. Also there is no need of conformational changes for the transportation process.

Hence, the statement is true.

Conclusion

Therefore, the statement, “Transport by transporters can be either active or passive, whereas transport by channels is always passive” is true.
