This organelle functions in receiving vesicles

This preview shows page 13 - 18 out of 23 pages.

This organelle functions in receiving vesicles, sorting the contents, and re-packaging the contents into a new vesicle to be shipped to a new location.Two-sides the golgi: cisand trans.cis-side (closest to the ER) receives vesicles. Because the membranes are similar to the ER, the vesicles fuse with the golgi and dump their contents inside.These contents move through the golgi’s membrane layers, or cisternae, to the opposite side.During this process, the vesicle contents are sorted (size and chemical properties).Once sorted, the contents are then packed into new vesicles and shipped from the trans-side of the golgi.

LysosomeOrganelle that is a product of the golgi.A specialized vesicle created that contains up to 40 different enzymes that all can be used for digestion of cellular material.Can change the pH on their interior to become rather acidic (~pH 5).Enzymes within, known as acid hydrolases, are activated upon acidic conditions.These membranous organelles fuse with other vesicles that contain digestible material.What does a cell need to digestFood particlesBacteria that enter the bodyOld/Non-functional OrganellesONLYSOME

Many plant cells lack lysosomes, but they do have a large membranes where they store both water and enzymes used for digestion.Large = Can take up 80% or more of the cell’s volume!Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.Plant cells also have a cell wall that keeps the cell’s shape rather ridged.The central vacuole, when full, provides the cell with internal support by filling in areas between the membrane and cytosol.Central Vacuole

Membrane-bound organelle that is much like a lysosome in structure, but is not created by the golgi.Contents are enzymes that are made from free-floating ribosomes and later packaged into a vesicle. Many of the enzymes found within are oxidizing enzymes used for detoxification and energy synthesis in both plant and animal cells.Detoxification of chemical substances such as drugs and alcohol occurs here.So many enzymes with in the structure that the interior can crystalize.The term “peroxisome” comes from the byproducts created through the oxidizing enzymes chemical reactions: hydrogen peroxide (H2O2).PeroxisomeHydrogen peroxide (H2O2) can be hazardous to a cell (think of what happens when you use this to clean a cut).Another enzyme, catalase, is also a component of peroxisomes to chemically change 2H2O2 to less hazardous substances: 2H20 + O2
