WorksheetsWeekly L2 Bio Quiz 3: Passive and Active transport
Total questions: 10
Worksheet time: 6mins
Moves molecules down a concentration gradient
Cytosis
Cytokinesis
passive transport
active transport
moves molecules up a concentration gradient
cytosis
cytokinesis
passive transport
active transport
Types of passive transport
osmosis
diffusion
endocytosis
exocytosis
types of active transport
hypertonicty
exocytosis
facilitated diffusion
transcytosis
Must be facilitated by carrier proteins
protein channel
active transport
protein pump
facilitated diffusion
The cell membrane folds around and envelops the material being transported. The membrane then pinches off to form a free vesicle inside the cell that contain the material.
endocytosis
Protein channel
Protein pump
exocytosis
A vesicle inside the cell, containing the substance being transported, moves to the cell membrane. Here the membrane of the cell and the vesicle merge together, expelling the vesicle contents out of the cell.
exocytosis
channel protein
endocytosis
protein pump
Results in the creation of a charge imbalance across the cell membrane
hypotonicity
protein channel
sodium-potassium pump
hypertonicity
The solute concentration is the higher than the inside of the cell.
isotonic
hypertonic
hypotonic
icitonic
what happens if you eat too much salt?
no water movement at all
water moves out of the cell it shrivels
cells become turgid
water moves into the cell it becomes lysed
