Does Active Transport Require energy?
Yes
100
What is endocytosis ?
Endocytosis- molecules are brought into cell
100
Does passive transport need energy?
No
100
What is diffusion?
Molecules move from high to low
100
What are protein transports for?
Help larger molecules cross the membrane
200
How do molecules in active transport travel through the concentration gradient ?
Against concentration gradient, low to high
200
What does against the concentration gradient mean ?
Low to high
200
What molecule does osmosis work with?
Water
200
What is the difference between diffusion and facilitated diffusion?
Facilitated needs transport proteins
200
Is low concentration inside or outside of the cell?
Inside the cell
300
Which active transport method uses a transport protein (helper)?
Pump
300
How many types of transports does active transport have?
3
300
How do molecules in passive transport travel through the concentration gradient ?
With concentration gradient, low to high
300
What happens in osmosis?
Water moves through membrane from high to low
300
What is the cell membrane for?
Regulate what goes in and out of cell
400
What is exocytosis ?
Exocytosis- molecules are thrown out of cell
400
What is ATP?
Energy
400
Which passive transport method uses a transport protein (helper)?
Facilitated diffusion
400
What does with the concentration gradient mean ?
High to low
400
What cells have cell membrane?
Eukaryotes and Prokaryotes
500
What are the three types of active transport?
Transport Protein, Endocytosis, and Exocytosis
500
What happens during protein transport?
What happens during pump?
500
What are the three types of passive transport?
Diffusion, Osmosis, and Facilitated diffusion
500
Why does facilitated diffusion need a transport protein?
Molecules are bigger and cannot cross
500
What is this?
Cell membrane
