Chapter 3 Cell Transport Flashcards
General term for the type of transport that requires ATP
Active transport
Term used to describe the ability of the cell membrane to allow some substances to pass but not others
Selective permeability
characteristics of compounds that can pass through the cell membrane
Small fat soluble proteins and carrier (for polar substances) and positive charge
Four basic examples of passive transport
Osmosis, diffusion, filtration, & facilitated diffusion
Movement of fat soluble substances from high to low concentration across the membrane
Diffusion across cell membrane
Three substances that diffuse (simple diffusion) across the membrane
Oxygen carbon dioxide and fat
Movement of polar substances through a protein carrier from high to low concentration across the membrane
Facilitated diffusion
Three substances that will move across the membrane by facilitated diffusion
Polar amino acids glucose and ions
Of water across the cell membrane from areas of high concentration to low concentration
osmosis
of two solutions the one that has more salt (solutes)
Hypertonic solution
Of two solutions the one that has less salt (solutes)
Hypotonic solution
Solutions that contain the same amount of salt (solutes)
Isotonic solutions
Concentration of an isotonic NaCl solution (relative to blood)
0.9% NaCl
Concentration of an isotonic glucose solution (relative to blood)
5% glucose
Exploding of a red blood cell in a hypotonic solution
Hemolysis
