Which form of cellular transport can move material from a low concentration area to a high concentration area?
Diffusion
Facilitated Diffusion
Osmosis
Active Transport
Your legs are swelling due to water retention. Which of the following would use the process of osmosis to reduce water retention in your legs?
Soaking in salt water
Blood-letting with leeches
Wrapping your legs in bandages
Laying in bed to rest
Which of the following is NOT a characteristic of the cell membrane?
Forms a protective boundary between the inside and outside of the cell
Controls what enters and leaves the cell
Composed of a double layer of phospholipids
Contains high amounts of cellulose to maintain structure
Which of the following best defines facilitated diffusion?
Water molecules pass through the cell membrane, moving from high to low concentration.
Small molecules move from high to low concentration across the cell membrane.
Molecules pass through a channel protein, moving from high concentration to low.
Molecules use energy from ATP to pass through a channel protein against the concentration gradient.
Semi-permeable membranes...
Allow all materials to pass through freely
Allow some materials to pass through freely, but stops other materials
Stop all materials from passing through
Are rigid to protect the cell from viruses
Which of the following best describes the difference between active and passive transport?
Active: moves material against the concentration gradient - Passive: moves material with the concentration gradient
Active: moves material with the concentration gradient - Passive: moves material against the concentration gradient
Active: uses no energy - Passive: uses energy
Active: allows water, oxygen, and carbon dioxide to enter the cell - Passive: allows large molecules like lipids to enter the cell
