Kim chi lab
what made the water leave the cabbage the day of kimchi lab!
what is salt!
True or false: A substance naturally moves from an area of higher to lower concentration!
what is True!
What is osmosis?
Osmosis is the movement of water molecules across the cell membrane from an area of low concentration to an area of high concentration.
Is simple diffusion passive or active transport?
What is Passive Transport
what has lower concentration, salt or the cabbage!
what is salt!
Molecules that pass through the cell membranes by facilitated diffusion:
A: Large molecules
B: hydrophobic molecules
C: Oxygen molecules
D: two of the above
Two of the above!
what are Hydrophobic molecules and Large molecules!
which type of transport requires energy!
what is Active transport!
True or False:
Simple diffusion requires an input of energy.
False
Does the cabbage shrink or swell!
what is shrinking!
True or false:
The two basic ways transport can occur are passive transport and simple diffusion!
what is False!
The sodium potassium pump moves___ ions out of a cell!
what is Sodium!
True or False:
Facilitated diffusion is passive transport.
True
if there was salt in the cabbage would that that make it shrink or swell!
what is swelling!
The sodium potassium pump involves:
A: Carrier proteins
B: Channel proteins
C: Vesicles
D: All of the above
what are Carrier Proteins!
True or false:
Exocytosis releases substances outside of a cell
what is True!
What is facilitated diffusion?
A passive form of transport where molecules move across a cell membrane down their concentration gradient with the help of transport proteins, requiring no cellular energy.
Why is salt added to cabbage when making kimchi?
so all the water leaves the cabbage so you can make kimchi
True or false:
Only very small molecules can pass through the cell membrane by simple diffusion!
what is True!
The diffusion of water is termed?
What is Osmosis!
What is a simple diffusion?
The passive movement of small, uncharged, or lipid-soluble molecules directly across a cell membrane from an area of high concentration to an area of low concentration, requiring no external energy.
