MPI U2 Quest Flashcards
anything that takes up space
matter
basic unit of matter
atoms
A charged atom
ions
pure substance
that is made up of
only 1 type of atom
elements
atoms of the same element that have a different number of neutrons
isotopes
graphite
carbon
the chemical element of atomic number 1.
hydrogen
(biological catalysts)
are proteins
-ase
enzyme
the chemical element of atomic number 8 and the life-supporting component of the air.
oxygen
element needed to make protein
nitrogen
a substance formed when two or more elements are chemically bonded together
compounds
smallest part of a compound
molecules
“sharing of electrons” to form an electrical attraction
covalent bonds
process where molecules are broken apart by “adding” water.
hydrolysis
Water is the most important….
inorganic compounds
Made by organisms
Contain C H (Carbon and hydrogen)
often form HUGE macromolecules from long chains of smaller molecules.
organic compounds
sugars and starches
Elements: C H O
ratio of elements H:O 2:1
carbohydrates
Building blocks of carbohydrates, simple sugars
“ring pop”
monosaccharides
two monosaccharides combined
disaccharides
“many” (3 or more) monosaccharides linked together in a single chain.
used for storage and structural components of organisms.
polysaccharides
used for energy storage in roots, stems, and leaves
starch
branched polysaccharide used for energy storage in the liver of organisms
glycogen
is made of polysaccharide chains
cellulose
A sequence of amino acids (polypeptide chain) interact to form shapes, these shapes fold up to form three dimensional structures
Elements – CHON (nitrogen!)
Building blocks – amino acids (20 different ones)
proteins
2 amino acids combined by dehydration synthesis.
dipeptide
covalent bond that joins two amino acids together
peptide bond
3 or more amino acids combined together
polypeptide
build two types of proteins, structural and chemical
amino acids
speed up or slow down a reaction, control rate of activity!
catalyst
area of enzyme that touches the substrate, chemical reaction takes place here.
active site
distortion of an enzyme molecule at high temperatures.
denaturation
- Problem -?
- Research
- Hypothesis -.
Scientific Method
the substance on which an enzyme acts
substrate
