If the dots represent sugar what direction will the water flow?
Into the cell
Out of the cell
Both equally (equilibrium)
Which molecule is in equilibrium? How can you tell?
Molecule A; equal amounts inside and outside
Molecule B; passive movement into the cell
Molecule C; equal amounts inside and outside
Molecule C; all molecules are inside the cell
What is the difference between active and passive transport?
Active is high to low; Passive is low to high
Active uses no cell energy; Passive uses cell energy
Passive is high to low and uses no energy; Active uses energy and is low to high
Passive uses no cell energy
What are the types of passive transport? Select all that apply.
Simple diffusion
Facilitated diffusion
Endocytosis
Osmosis
Protein pumps / carrier proteins
Fill in the blank:
Osmosis is the movement of ________ across a cell membrane from high to low.
Carbon dioxide
Starch
Water
Oxygen
What is ATP and what kind of transport uses it?
Energy; passive transport
Protein; simple diffusion
Energy; active transport
Protein; endocytosis
Why does molecule A move into the cell?
Active transport by moving from high to low concentrations
Passive transport by moving from high to low concentrations
Active transport by moving from low to high concentrations
Passive transport by moving from low to high concentrations
_____________ is the free movement of particles across the membrane with the concentration gradient
diffusion
facilitated diffusion
active transport
fusion
What is the movement of particles with the concentration gradient using protein "helpers"?
diffusion
facilitated diffusion
active transport
enzymatic reactions
Some cells move large particles out of the cell through the process of:
Protein Synthesis
Endocytosis
Exocytosis
Cytoplasmic Streaming
Active transport is when molecules move ________ the concentration gradient.
against
up
down
with
This picture is a representation of what type of transport?
Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.
Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
