What is Active Transport?
200
Name the two structural components of the cell membrane.
What are Phospholipids and Protein Channel or Surface Proteins?
200
What is the function of the cell membrane?
to control what exits/enters the cells
200
The main function of the cell membrane

200
What type of transport is osmosis?
Passive Transport
200
Water moves into a cell when the solution surrounding the cell is
What is Hypotonic?
300
The sodium-potassium pump is a form of active transport that moves sodium ions outside the cell and potassium ions inside the cell. Why is energy needed for active transport?
2. Ions are moving Low to High (against the concentration gradient)
300
What does the term semi-permeable mean?
Some materials are allowed in the cell, while others are blocked.
300
The type of transport is shown in the diagram
What is Facilitated Diffusion?
300
__________ is the diffusion of water across a semipermeable membrane.
What is Osmosis?
300
Water will move OUT of a cell when the surrounding solution is______________
What is HYPERTONIC?
400
What cellular transport did this cell model demonstrate?
What is Osmosis (movement of water in/out of cell)?
400
The reason cells move substances in and out
What is maintain homeostasis, release waste, and/or transmit molecules to other parts of the body?
400
What is 2 differences between active and passive transport?
One uses energy on does not
400
The direction substances move during active transport
What is AGAINST the CONCENTRATION GRADIENT?
400
What type of cell or how will the water move?
hypotonic; water will move into the cell.
500
The structure that makes facilitated diffusion different from other types of passive transport
What is a CHANNEL PROTEIN?
500
Which picture represents endocytosis and exocytosis.
Explain.
1st-exocytosis (goes OUT)
2nd-endocyctosis ( INTO)
500
If a freshwater fish was moved from a freshwater aquarium to a saltwater aquarium, what will occur?
The fish cells will shrink, saltwater will pull the water out of the cells.
500
During transport water will move in what direction?
out of the cell; hypertonic
500
A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level. Name the term?
Homeostasis
