Active transport Flashcards
1
Q
Active transport
A
Process that enables materials to move across a cell membrane
against a concentration gradient. Requires energy (ATP)
2
Q
Two types:
A
Pumps, bulk transport
3
Q
definition of
Pumps:
A
Movement of molecules against the concentration gradient
using a protein, and requiring energy (ATP)
4
Q
Bulk Transport:
A
Movement of large molecules in a membrane-bound sac across
the membrane
5
Q
Bulk transport 4 types:
A
Endocytosis, Pinocytosis, Exocytosis, Phagocytosis
6
Q
Endocytosis:
A
Process by which large molecules exit the cell
7
Q
Pinocytosis:
A
small, dissolved substances are taken up by membrane folding
8
Q
Exocytosis
A
a process of taking material into the cell by pockets in the cell membrane
9
Q
Phagocytosis
A
particles being taken in are solid and large
