Transport in Cells Flashcards
(8 cards)
1
Q
What two processes are part of transportation in the cells?
A
Osmosis and Diffusion
2
Q
What does movement of gases, nutrients, water, and electrolytes dependent on?
A
- Differences in concentration
- Membrane permeability
- Molecule size
3
Q
What is the net movement of particles?
A
Diffusion
4
Q
What is the concentration gradient for diffusion?
A
High concentration to lower concentration
5
Q
What is the typical result of diffusion?
A
Equilibrium of particles
6
Q
Does diffusion require energy?
A
No due to the concentration gradient
7
Q
What are examples of diffusion?
A
Alveoli in the lungs (diffusion of gases in the blood) and Villi in the small intentine (diffusion of digested products into blood)
8
Q
What is the diffusion of a solvent, in most cases water, across a selectively permeable membrane?
A
Osmosis
