By increasing the length of time a neurotransmitter remains in the synaptic gap, strengthening its effects B. by blocking a receptor site and preventing the neurotransmitter from acting C. by bonding with the neurotransmitter and changing its molecular weight and shape D. by mimicking a particular neurotransmitter and producing the same effect

by bonding with the neurotransmitter and changing its molecular weight and shape

Explanation:

Here is the complete question:.

Which of the following is NOT one of the ways discussed in the text that drugs can interfere with synaptic transmission?

A) by blocking a receptor site and preventing the neurotransmitter from acting

B) by mimicking a particular neurotransmitter and producing the same effect

C) by increasing the length of time a neurotransmitter remains in the synaptic gap, strengthening its effects

D) by bonding with the neurotransmitter and changing its molecular weight and shape

The answer is

D. by bonding with the neurotransmitter and changing its molecular weight and shape

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
