hemolysis
the rupture or destruction of red blood cells.
Which of these can rapidly pass directly through the phospholipids of the plasma membrane, without the help of a transport protein?
A
What property of dishwashing liquid makes it useful to wash grease from pans?
Amphipathic nature
You can recognize the process of pinocytosis win
Cell is in golfing extracellular fluid
Endocytosis
Decreases the surface area of the plasma membrane, forms vesicles from inward folding of the plasma membrane
Identify structure A
Glycoprotein
If a red blood cell is placed in a salt solution and burst, what is the tenacity of the solution relative to the interior of the cell?
Hypotonic
Yes I ptosis moves materials __________ a cell via _______
Into... Membranous vesicles
Exocytosis
Kris large molecules out of the cell, increases the surface area of the plasma membrane, requires fusion of vesicles with the plasma membrane
Which of the following particles can diffuse easily through a cell membrane?
Oxygen
Facilitated diffusion is a type of
Passive transport
White blood cell engulfing a bacterium is an example of
Phagocytosis
Both exocytosis and endocytosis
Requires cellular energy, transported substance never physically cross the plasma membrane
Structure a is a
Solute
Crenation
This happens when a cell shrinks and shrivels; can result in cell death if severe.
Structure a in the figure is a
Transport proteins
Structure be is a
Transport proteins
Osmosis is a type of diffusion
True
The water soluble portion of a phospholipid is the polar head, which generally consist of a glacier molecules linked to a phosphate group
True
Identify structure D
phospholipid bilayer of membrane
What is the function of structure E?
stabilization of the phospholipids
