Cell transport #3 & #4 10/26/22
This molecule powers the sodium-potassium pump
ATP
Which of the following is not a type of passive transport?
Endocytosis
which of the following is not a type of passive transport
Endocytosis
A form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.
Exocytosis
Which type of passive transport uses proteins to help molecules pass through the membrane?
Facilitated diffusion
The cells seem to be swelling and about to burst what type of solution are they most likely in?
Hypotonic
An example of pump transport is
Na+/K+ Pump
Most abundant type of lipid in the cell membrane
Phospholipids
This plant would most likely be
Stiff and rigid
Cell membranes are described as selectively permeable. Four students were asked to explain what this means. Which one is correct?
Student 3: Cell membranes regulate which substances can enter and exit the cell.
What will happen to the cell in the given solution?
Swell up
What would happen to a cell placed in a hypertonic solution
The cell would shrink
What is the force inside the central vacuole called?
Turgor Pressure
In this picture, which way will the water move?
Water will move into the cell
Movement of SOLUTE through the cell membrane from high to low concentration is called.....
diffusion
Nemo and other ocean dwelling fish cannot survive in freshwater because
freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burstfreshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst
What type of solution is this cell in?
isotonic
Moving from areas of LOW concentration to areas of HIGH concentration is called?
Active Transport
Passive Transport
Does NOT require cell energy
When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of
Equilibrium
In this picture, how do you classify the solution?
The solution is hypotonic
What type of organelle is used during endocytosis and exocytosis?
Vesicle
what type of organelle is used during endocytosis and exocytosis
Vesicle
What is the difference between active and passive transport?
Active uses ATP (energy) and passive does not need energy
white blood cells engulfing invading bacteria is an example of
Endocytosis
Which type of transport gets rid of wastes?
Excoytosis
The cells seem to be shriveled and dehydrated what type of solution are they most likely in?
Hypertonic
If the dots represent sugar what direction will the water flow?
Into the cell
This plant will most likely be ( look t the right side)
Limp or wilted
Energy from ATP changes the carrier protein's _______ to move molecules in and out of the cell.
Shape
What is diffusion?
The movement of particles from high conc. to low conc. in a given space
What protects carrot cells from swelling too much when it rains?
They have cell walls that keep them from swelling too much.
In plant cells, the force, exerted by the flow of water, within the cell that pushes the plasma membrane against the cell wall. This force gives plants structure and helps them stand up and not wilt.
Turgor Pressure
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. To move these molecules against their concentration gradient, a ___________ protein is needed.
carrier
Active transport across a cell membrane from low to high concentration, requires
energy (ATP)
What type of solution allows water to enter the plant cell?
hypotonic solution
In an isotonic solution which way will the water flow
it will flow both ways at equal rates
Active transport is the movement of large materials across a cell membrane from ______ to ______ concentration
low to high
The movement of water through a semi-permeable membrane is called
osmosis
What type of transport is this?
endocytosis
What type of solution is this cell in?
hypotonic
