Unit 2: Cells- active transport across cell membrane Flashcards
1
Q
active transport
A
requires energy (usually ATP)
2
Q
in active transport cells move from ________ concentration to ________
A
low to high
*against concentration gradient
3
Q
gated channels
A
only open to allow passage with stimulation
4
Q
ion-gated channels
A
get stimulation from neurotransmitter activity
5
Q
voltage-gated channels
A
get stimulation from a change in electrical charge
6

A
form of active transport that gets large molecules into the cell
- 2 types
7
Q
phagocytosis
A
cellular eating
- type of endocytosis
8
Q
pinocytosis
A
cellular drinking
- type of endocytosis
9
Q
exocytosis
