What distinguishes active transport from passive transport in the context of neurotransmitter reuptake?
Understand the Problem
The question is asking about the differences between active and passive transport specifically in relation to the reuptake of neurotransmitters in the nervous system. It seeks to clarify mechanisms and the conditions under which each type of transport operates.
Answer
Active transport requires energy to move substances against their concentration gradient.
Active transport distinguishes itself by requiring energy to move neurotransmitters against their concentration gradient, while passive transport does not require energy.
Answer for screen readers
Active transport distinguishes itself by requiring energy to move neurotransmitters against their concentration gradient, while passive transport does not require energy.
More Information
Active transport in the context of neurotransmitter reuptake involves the use of ATP to move neurotransmitters back into neurons or glial cells. This process is critical for resetting the synaptic cleft for another round of neurotransmission.
Tips
A common mistake is confusing the direction of the movement; active transport moves substances against their concentration gradient, while passive transport moves substances along the gradient.
