It is notably the site of tissue respiration." [GOC:giardia, ISBN:0198506732] EOG8H48HH GO:0048488 1/153 synaptic vesicle endocytosis biological_process "An endocytosis process that results in the invagination of the axonal plasma membrane to create a membrane-bounded vesicle. This process takes up excess membrane that would otherwise accumulate at the presynaptic terminal due to fusion of vesicle membranes during neurotransmitter release. The vesicles created may subsequently be used for neurotransmitter storage and release."
