Cell membrane structure depicts the plasma membrane composed of a double layer or lips molecules with protien molecules. |
Fluid mosaic model |
|
Contains a polar hydrophilic head and non polar hydrophobic tail |
Phospholipids |
|
Are lipids with attached sugar groups located on the outer layer of the call membrane |
Glycolipids |
|
Inserted into the lipid bylayer. This structure feature allows them to interact with both nonpolar lipid tails in the membrane and the water inside and outside the cell |
Integral protiens |
|
Primary energy transferring molecule in cells the provide a form of energy that is immediately usable by all body cells |
ATP |
|
Membrane protiens that can be enzymes that a loosely attached to integral protien. The are used cell division and muscle contraction. |
Peripheral protiens |
|
Used as an identification tag for cells. Help communicate with other cells. Know as sugar covering of cells |
Glycocalyx |
|
Helps prevent molecules from passing through the extracellular space between adjacent cells. |
Tight junctions |
|
Known as building bodies, serve as anchoring junctions. They prevent the separation of adjacent cells |
Desmosomes |
|
Know as communicating junctions between cells. |
Gap junctions |
|
Are chemicals that bind specifically to plasma membrane recepters |
Ligands |
|
A regulatory molecule that acts as a middleman or relay to activate a membrane bound enzymes or I lon channel |
G protien |
|
The cellular material between the plasma membrane and nucleus;also the site of most cellular activity |
Cytoplasma |
|
The power plant of the cell, provides most of the cells ATP |
mitochondria |
|
Small dark granules composed of protiens and RNA. the are the site for protien synthesis |
Ribosomes |
|
External surface is stubbed with ribosomes. It ribosomes manufacturers all protiens secreted from cells. |
Rough er |
|
Does not synthesis protiens but metabolize lipids and synthesize cholesterol.also works as a detoxifier |
Smooth er |
|
Consists of stacked and flattened membrane sacs . Know as the traffic director for cellular protiens |
Golgi apparatus |
|
Resembles small small lysosomes. Know as peroxide bodies. Contains powerful enzymes. |
Peroxisomes |
|
Know as disintegrator bodies. They contain activated digested enzymes. |
Lysosomes |
|
Is a tendency for molecules or ions to move from a higher concentrated area to a lower one |
Diffusion |
|
Refers to the ability of a solution to change or tone cells by altering the cells internal water volume |
Tonicity |
|
The transport or large particles in vesicles is called |
Vehicular transport |
|
The moving of items into each the cell |
Endocytosis |
|
The moving of teams out of the cell |
Exocytosis |
|
The moving of items across the cell |
Transcytosis |
|
Know as cell drinking. The intake of fuilds into the cell |
Pinocytosis |
|
Called a network within the cells. Two different types |
ER |
|
Stubbed with ribosomes that synthesize protiens and sends them to the golgi apparatus. |
Rough er |
|
Does not synthesize protiens but other like cholesterol and metabolize lipids. |
Smooth er |
|
Known as a traffic director in the cell for protiens. It's primary functions is to modify, concentrate, and package the protiens and lipids made in the rough er. It also exists these items from the cell |
Golgi apparatus |
|
Are spherical sacs containing powerful enzymes oxidases and catalases. |
Peroxisomes |
|
Born as endosomes that contain inactive enzymes. Known as disintegrator bodies and demolition crew. Digest particles during endocytosis. |
Lysosomes |
|
Known as the cell skeleton. |
Cytoskeleton |
|
It acts as a microtubule organizing center. |
Centrosome |
|
Known as the control center of the cell |
Nucleus |
|
The process of cell division |
Mitosis |
|
The four phases of mitosis in order |
PMAT: prophase, metaphase, anaphase, and telephase |
|
The study of the microscopic structure of tissues |
Histology |
|
Carbohydrates are stored in the liver and muscles in the former of |
Glycogen |
|
Average body temperature is |
37 degrees centigrade |
|
Functional characteristics of life |
Digestion excretion growth, maintenance of boundaries movement responsiveness reporduction |
|
The most abundant protien in the human body is |
Collegen |
|
What is a chain of 25 amino acids |
Polypeptide |
