Membrane Structure
Another name for the Cell membrane is
Phospholipid Bilayer or Plasma membrane, or semipermeable membrane
What makes up the majority of a cell membrane
Phospholipid
A category of transport that does not require energy input
Passive Transport
Someone sprays perfume in the back of the class, it can be smelled in the front of the room
Diffusion
Name the type of solution: A cell has a 25% solute concentration while the solution has a concentration of 10%
Hypotonic Solution
The model that explains why a cell membrane can flex or move
The Fluid Mosaic Model
What provides the flexibility for a cell membrane
Cholesterol
This type of cell Transport moves small polar and nonpolar molecules across a cell membrane
Simple Diffusion
In an effort to remove slugs from your garden you sprinkle salt on them. The slugs shrivel up
Osmosis
Name the type of solution: An IV drips lactate ringer's solution into your bloodstream without any impact on your blood cells.
Isotonic Solution
Which 3 Biomolecules compose the cell membrane
Lipids, Proteins, Carbohydrates
What type of protein is found on only one side of the cell membrane
Surface ( Peripheral) Protein
This type of cell transport involves the movement of water across a cell membrane
Osmosis
In order for oxygen to be used in cellular respiration it must first cross the cell membrane. WHich process does it use?
Simple Diffusion
Which direction will the water move: A freshwater fish is placed in a saltwater aquarium
The water will move out of the fish and into the saltwater
The type of protein that travels through the membrane
Integral Protein
A protein that helps to move molecules across a cell membrane.
A Channel Protein
This type of cell transport requires the use of proteins to move large or charged molecules across a cell membrane
Facilitated Diffusion
With a signal from a hormone, glucose is able to pass through the cell membrane
Facilitated Diffusion
Explain why a toad will gain mass after sitting in a puddle
The water in the puddle will move through the toads skin and into its cells since there is a higher concentration of solutes and lower concentration of water inside the toad.
Combines 2 different biomolecules and is used for cell signaling or cell recognition
Glycoprotein
Identify the hydrophilic and hydrophobic parts of the cell membrane
Hydrophilic - Phospholipid Heads
Hydrophobic - Phospholipid tails
This type of cell transport moves large molecules such as polysaccharides into a cell with the use of a vesicle.
Endocytosis
The release of digestive enzymes by the pancreases using vesicles
Exocytosis
A plant cell and animal cell are both placed into pure water. What will happen to each cell? Will both cells survive this event, why or why not?
Water will rush into the cells. The plant cell will survive due to the cell wall but the animal cell will burst as it lacks a cell wall.
