is anything that occupies space and has mass
State of mater
solid, liquid and gaseous state
is the capacity to do work
is energy in action
Is stored energy
form of energy
chemical energy, electrical energy, mechanical energy, radiant energy or electromagnetic energy
Make up about 96% of our body
carbon, oxygen,hydrogen,and nitrogen
means indivisible, are clusters of even smaller particles called protons, neutrons and electrons.
a major componenof both organic(carbon conaining) and inorganic (non-carbon contain) moleculas. t it is need for the production of cellular energy.
a primary component of all organic molecules, which include carbohydrates, lipids(fat) proteins and nucleid acid.
a component of proteins and nucleic acid.
is equal to tne number of protons
the mass number
is the sum of the protons and neutrons
elements have two o more structural variation
the disintegration of a radioactive nucleus may be compared to tiny explosion
combination of two or more atoms bind, they form molecules of a compound
Are substance composed of two or more component phisically intermix
homogeneous, will not settler
Are heterogeneous mixtures. Often appear translucent or milky and although the solute particle are larger that those in true solutions, they still o not settle out.example jell-O
Are heterogeneous mixture with large, often visible solutes that tent to settle out. Example mixture of salt and water and blood
It is a energy relationship between the electrons of the reacting atoms.
All the chemical reaction has occur in a living organs
Chemical that help speed up chemical reaction with out itself being used up
Something oxide is remove
Any chemical that does not contain carb
Any chemical that contain carb
Everything disolve.ex salt
Is never a true solution . Ex. Flour
Is not a truly dissolve because is too heavy
Ph is the scale on the number of hydrogen ion in solution
Is an ionic compound containing cations and anions
Opposite of dehydration synthesis
Types of chemical bonds
Ionic bond, covalent bond, hydrogen bond
a bond which electrons are complely lost or gained by the atoms involved
Containing atoms with different electrons -attracting ability
Two different atoms share the same electrons
Is the study of the chemical composition and reaction of living matter
Is the most abundant and important inorganic compound in living material. It make up 60-80% of volume of most living cells
Have a sour taste, can react with many metals.
Acid and bases
Like salt they are electrolyte
A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH.
A group of molecules that includes sugar and starches
Or simple sugar , ex. Glucose , fructose, galactose.
Double sugar, it's formed when two monosaccharides are join by dehydration synthesis
Simple sugar linked together by dehydration synthesis
Contain carbon, hydrogen,and oxygen.( fat in the body)
Neutral fats, it composed of two types of building block, fatty acid and glycerol. Fat deposits
Are linear chains of carbon and hydrogen atoms with an organic acid group at the end.
electrically charged particle due to loss of an electron
a bond which electrons are shared equally
legs moving the pedal of a bicycle
when the bondsof ATP are broken, is released to do cellular work
represented by the flow of charged particles along a conductor, or flow of ions acrossa membrance
the structural basic for manufactory of all body steroids. a component of cell membrane
increasing the risk of heart disease even more that the solid animal fat
are modified triglycerides
are fat soluble and contain little oxygen
the building block of proteins
two united amino acid
the nucleic acid
composed of carbon, oxygen, hydrogen, nitrogen and phosphorus, are the largest molecules in the body. has two major class of molecules Deoxiribonucleic acid(DNA) and ribonucleic acid (RNA)
is the genetic material
carried out the genetic instructions for protein synthesis
Adenine, guanine, cytosine, thymine
Adenine, guanine, cytosine, uracil
