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
