|
A precedure performed before an organ from one individual is transplanted into another. |
tissue typing |
|
|
The organellies that can digest and destroy cells are called |
Lysosomes |
|
|
-membranous-walled organellies -contain digestive enzymes -have a protective function (eat microbes) -formerly though to be responsible for apoptosis (programed cell death) |
Lysosomes |
|
|
small fingerlike cell extension of the plasma membrane that increases absorptive surface of the cell. |
microvilli |
|
|
______ increase the absorption rate of nutrients in the blood. |
microvilli |
|
|
-composed of inner and outer membranous sacks -involved with energy-releasing chemical reactions -contains one DNA module |
Mitochondria |
|
|
The _____ provide energy-releasing chemical reactions that go on continuously. |
mitochondria |
|
|
A cellular structure that has the ability to secrete digestive enzymes |
lyposomes |
|
|
—synthesizes proteins, nicknamed “protein factories.”
—may attach to rough endoplasmic reticuli or lie free in cytoplasm |
Ribosome |
|
|
—a stack of flattened membranous sacs that chemically process and then package substances from the endoplasmic reticulum.
|
Golgi apparatus
|
|
|
—a membranous capsule containing a large folded membrane encrusted with enzymes.
—Major function is ATP synthesis, called the “powerhouses” of the cell. |
Mitochondria
|
|
|
—contain chemicals (enzymes) that can digest food compounds and destroy microbes that invade the cell. They are called “digestive bags.” Paradoxically, if their enzymes escape from the lysosome sacs into the cytoplasm, they can also digest and kill the cell. Hence they are also called “suicide bags.”
|
— Lysosomes
|
|
|
—paired organelles that exist in every cell. They play an important role in cell division.
|
Centrioles
|
|
|
movement of particles from an area of high concentration to an area of lower concentration. Particles scatter themselves evenly throughout an available space.
|
Diffusion
|
|
|
movement of both water and small solute particles through a membrane because of a greater pushing force on one side of the membrane than on the other side. Movement is from an area of high pressure to an area of lower pressure.
|
Filtration
|
|
|
An _____ _______ is a protein structure in the cell membrane that acts as a carrier. It uses energy from ATP to actively move ions across cell membranes against their concentration gradients; that is, against diffusion.
|
ion pump
|
