Introduction to Cell Transport: Plasma Membrane Flashcards
What is the primary function of the Plasma Membrane?
Allows certain particles/molecules in and out of the cell.
What are all the organisms that have a Plasma Membrane?
Bacteria, Plants, Animals, and Humans.
What does Homeostasis mean?
Balance.
What terms best describe Homeostasis?
Balanced, and Stable.
What is the Plasma Membrane made mostly of?
Lipids, and Proteins.
How many layers is the Bilayer?
Two.
What is the Bilayer made up of that is water loving and water fearing?
Heads: Water Loving
Tails: Water Fearing
What process are Channel Proteins involved in?
Facilitated Diffusion.
Cells using passive transport USE ENERGY or DON’T USE ENERGY?
Don’t use energy.
Molecules move HIGH TO LOW or LOW TO HIGH during Passive Transport?
High to low.
Molecules move WITH or AGAINST during Passive Transport?
With.
What is diffusion?
The movement of particles from an area of high concentration to an area of low concentration.
How is spraying perfume an example of diffusion?
The paragraph says, “But, over time the particles begin to spread around the classroom, and eventually everyone can smell it.”
