Term
Homeostasis
Definition
balance within the body to maintian a normal conditions
Term
Postive and negative feed back
Definition
Negative feedback is the body bringing the body back to a certain set point IE a fever. Postive feedback increases the reacation much like child birth.
Term
Protons Nutrons Electrons
Definition

Protons have a + Charge

Nutrons have a Neutrual Charge 

Electrons have a - Charge

Term
Ion
Definition
Atom or Groups of atoms whos number of electrons are not equal to the number of protons giving it a net -/+
Term
Anion
Definition
Negitive ion attracted to an anode
Term
Cation
Definition
Has a net postive charge and is attracted to a cathode
Term
Ellectron shell
Definition
Electrons cirrculate the nucules occupying diffrent energy levels call the shell lower energy are on the bottom(inner) higher ones on the outside
Term
nuclus
Definition
center of a atom has to have a possitive charge
Term
Electron Cloud
Definition
electrons that swirl around nucules
Term
how do atoms form molocules
Definition
Atoms with partially filed shells interact with outher partially filled atoms to form molocules
Term
Explain Isotopes
Definition
Atoms with a set certain number of protons and nutrons in the nucules like Hydrogen
Term
Covalent bonds
Definition
Bonds that are made by sharring electrons these form molucues
Term
Ph stands for what, also expalin PH values
Definition
Potentional hydrogen 7.4Ph is normal blood while anything above 7 is alkaline and anthing below acidic
Term
Carabohydrates
Definition

Monosychride meaning 1 (glucose)

Discharides meaning 2(surcose)

Polosycharides meaning 3 ( starches) 

These provide fuel 

Term

Definition
amino acids
Term
Enzymes
Definition
Enzymes are a 3d complex sturucte enzymes bind to very specific substrates on the activation site they lower the energy required to breakdown substrate

Definition
Potrion of cell contains water, dissolved minnerals, and orgonelles
Term
Cytosol
Definition
Gel like matrix Supporting the cells shape and orgonelles
Term
Cytoskeleton
Definition
Microfilliments and microtubrcules that form the cells "skelton"
Term
Orgonell
Definition
cells organs
Term
Plasma Memebrane PM
Definition
Protective wall Provides nutritens and excertaions
Term
Cytoskeleton and its parts
Definition

Protein frame work of the cell kind of like the skelton of the cell hold everything

Microvilli-finger like projections surface area of the cell for absorption (small Intestine) 

Centrioles groups of microtubulues surrounding this is the centersome 

 

Term

Endoplasmic reticulum

Smooth ER

Rough ER

Definition

Responsible for protein systhieis (ribosomes)

Smooth ER- contain no ribosmes 

Routh ER- Contians Ribsomies and provied Active transport 

Term
