Question

use the diagram above to answer the next question. which one of the following actions causes material to enter the gap shown in the diagram? select one: a. endocytosis b. exocytosis c. facilitated diffusion d. diffusion

Explanation:

The diagram likely shows a synaptic cleft (gap) between a neuron and target. Exocytosis is the process where vesicles fuse with the cell membrane to release neurotransmitters (material) into the synaptic gap. Endocytosis takes material into the cell, facilitated diffusion and diffusion are passive transport of small molecules, not releasing material into a gap like this. So exocytosis causes material to enter the gap.

Answer:

b. exocytosis
