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
