Examples of Passive and Active Transport
Review from previous chapters
100
The movement of material without using cellular energy.
What is passive transport?
100
Passive transport does NOT require this
What is energy?
100
During Active transport, this IS required for molecules to pass through the cell membrane.
What is energy?
100
The two types of Endocytosis.
What are Phagocytosis and Pinocytosis?
100
The four groups of macromolecules.
What are proteins, carbohydrates, nucleic acids, and lipids?
200
The diffusion of water through a selectively permeable membrane.
What is Osmosis?
200
During passive transport, molecules move from an area of ---- concentration to an area of ---- concentration.
What is high to low?
200
During Active transport, molecules move from an area of --- concentration to an area of --- concentration.
What is low to high?
200
This allows some substances to pass through and not others.
What is a semi-permeable membrane?
200
An organized way of gathering and analyzing evidence about the natural world
What is Science?
300
When molecules cannot directly diffuse across the membrane, they pass through special protein channels in this process.
What is Facilitated Diffusion?
300
The three types of passive transport discussed in class.
What are Diffusion, Facilitated diffusion, and Osmosis?
300
The two main types of bulk transport.
What are Endocytosis and Exocytosis?
300
The state at which two solutions are at equal concentration.
What is equilibrium?
300
The variable that changes in response to the independent variable.
What is the dependent variable?
400
Water channel proteins that allow water to pass right through them.
What are Aquaporins?
400
Osmosis refers to this specific molecule traveling across a semi-permeable membrane.
What is water?
400
These are the forms of energy you would see in a cell membrane diagram when it is illustrating Active transport.
What are ADP or ATP?
400
The difference between Diffusion and Facilitated diffusion.
What are the use of protein channels?
400
The four key attributes of a scientist.
What are Curiosity, Skepticism, Creativity, and Open-Mindedness?
500
The force exerted by a net movement of water out of or into a cell.
What is Osmotic Pressure?
500
The lack of these in the cell membrane allows frogs and fish to lay their eggs in fresh water without the egg cells swelling and bursting.
What are Aquaporins?
500
These special enzymes are used during molecular transport to get large ions into or out of the cell.
What are protein pumps?
500
Single-celled organisms, like amoebas, eat by taking in materials through this process.
What is Endocytosis?
500
Allows experts to go over scientific papers for reliability and unbiased support.
What is Peer Review?
