Active Transport APbioU2

made and studied on my only free day

why does active transport use energy?

substances can be moved against (up) the gradient (low→high)

sodium-potassium pump is used to…

create a electrochemical gradient that will be used to ______.

Exocytosis

EXO →leaves, vesicle (from inside) with a substance fuses with PM

Endocytosis

ENDO → enter, substance (from outside) fuses with PM and makes a vesicle

Neurotransmitters use _____ when….

exocytosis when secreted out of the axon terminal

Pinocytosis

Form of endocytosis, PINO → small substances, liquids & blood cells

Phagocytosis

Form of endocytosis, PHAGO → large substances, food & cells & viruses & RBCs, digests w/ lysosomes

Co-Transport

ATP creates a gradient and a substance moves out of the PM (primary), that substances is used to help a substance outside the PM inside with a protein (secondary)
