Answers

1
Passive transport
substances move from low to high concentration
Requires energy from the cell
Does not require cellular energy
Requires carrier proteins to change shape
2

Simple diffusion
Osmosis
Carrier proteins
Endocytosis
3
sodium potassium pump
Is a form of passive transport.
Increases cellular concentration of sodium.
Decreases cellular concentration of sodium.
Requires protein channels.

Hypertonic solution increases swelling.
11
Purpose of the cell membrane
All the above.
Allow movement of substances in and out of the cell.
Maintain homeostasis.
Protect cell from outside environment.
12
Simple diffusion
Movement across membrane from hogh to low concentration
Requires channel proteins
Is a form of osmosis
Requires energy from the cell
13
Concentration gradient
Exists while studying
Concentration is the same on both sides of membrane.
Concentration is higher inside the cell.
Exist only in equilibriums.
14
process if engulfing large substances to get them inside the cell
Endocytosis
Facilitated passive transport
Exocytosis
Does not require cellular energy
15
Cells in equilibrium
Low concentration inside the cell compared to outside.
No concentration gradient exists.
High concentration inside the cell compared to outside.
Concentration gradient exists.
