Term
| Function of the cell membrane |
|
Definition
•Separates intracellular from extracellular environment
• Controls movement into and out of cell
• Signal transduction (provides communication) |

• membrane protein
(channel, carrier, cell recognition, receptors, enzymatic, junction) |
|
|
Term

|
Definition
| Decreases the effective temperature on cellular membrane |

|
Term
|
Definition
| Maintains cell shape and assistant movement of cell parts |
|

Term
|
Definition
| Cylinders of protein molecules present in cytoplasm, centrioles, cilia, and flagella |
|
|
Term

| Protein fibers that provide support and strength |
|
|
Term
|
Definition
| Protein fibers that play a role movement of cell organelles |
|
|
Term
|

Cellular structure built of microtubules that organize the mitotic spindle
Not found in plant cells |
|
|
Term
|

Vesicles that digest macromolecules and even cell parts
Not found in plant cells |
|
|
Term
| Components of the nucleus |
|
Definition
• Nuclear envelope
• Chromatin
• Nucleolus |
|
|
Term
|
Definition
| Double membrane with nuclear pores that enclose nucleus |
|
|
Term
|
Definition
| Diffuse threads containing DNA and protien |
|
|
Term
|
Definition
| Region that produces subunits ribosomes |
|
|
Term
|
Definition
Studed with ribosomes
Ribosomes of rough ER our site of protein synthesis
Proteins then move to tubules the endoplasmic reticulum to the Golgi apparatus for furtur processing
|
|
|
Term
|
Definition
| Contains enzymes that are important in synthesizing lipids, absorbing fats from digestive tract, and breaking down drugs |
|
|
Term
|
Definition
stacks of a half a dozen or so flattened, membranous sacs called cisternae.
This organelle refines, packages, and delivers proteins synthesized on the rough ER |
|
|
Term
|
Definition
Has two layers-an outer membrane and inner membrane
The inner membrane folds extensively in, forming shelf life partitions called cristae.
Adenosine triphosphate ATP
Powerhouse of the cell |
|
|
Term
|
Definition
| Vesicle that has various functions; breaks down fatty acids and converts resulting hydrogen peroxide water |
|
|
Term
|
Definition
| particles that carry out protein synthesis |
|
|
Term
|
Definition
| String of ribosomes simultaneously synthesizing the same protein |
