structural hierarchy basic cell chemistry
cell chemistry structural hierarchy fall 2014
everything is made up of 1 or more?
atoms are also known as
atoms can be?
living and nonliving
made up of more than 1 atom
ex of macromolecules
information systems, carry genetic material
large, stable molecules used to regulate physiology in body
proteins are good for
structure and enzymes
molecular level consists of?
cellular level is made of?
basic unit of all living systems?
specialized to perform specific tasks by the cell
T or F, you can not see most cells with the unaided eye
what makes up the tissue level?
groups of cells collected together to perform a common function
material between cells in tissues
how many types of tissues are there?
two types of tissues?
little to no intracellular material
lighter tissues ?
lots of intracellular material
made of multiple tissue types, diff combos
groups of different tissues working together for a common function
organ systems are?
order of structural hierarchy?
the structural hierarchy all together creates?
an individual unit
interconnection of structural hierarchy?
if something changes in one level, it will effect all other levels
3 levels of structural hierarchy?
what makes up gross anatomy?
what makes up microanatomy?
how many different types of atoms in nature?
92 atoms in nature are known as
all atoms are made up of various combos of?
atomic mass of proton?
determine the identity of an atom by the number of
atomic number =
number of protons
if you know the number of protons, then you know
atomic mass of electrons?
determines the chemical properties of an atom
for an unchanged atom, the number of protons = the number of _____
affect the chemical behavior of an atom
so much smaller than protons, that their atomic mass is irrelevant
these are about the same size of a proton
atomic mass of an atom?
#protons + #neutrons
atomic mass - atomic number =
number of neutrons
atomic mass of neutron?
atoms of any element that differ from one another by their neutrons.. changes the atomic mass
holds the protons and neutrons
electrons are in constant motion moving around the nucleus
orbitals are aka
outermost orbital holds?
8 valence electrons
all atoms want? to be stable
simplest type of bonding
give and take
in nuclear reactives, the isotope causes?
the element with an exception to the octet rule?
unequal sharing where molecule has a charge
polar covalent bonding
water molecules have ?
6 valence electrons
very weak bonds
effect the way other molecules interact with each other
through hydrogen bonding?
water clings together

6 main elements
most important inorganic compound
water makes up?
60-80% of cell volume
water must be in what form to be useable?
2 components of a solution

nonpolar compound, will only dissolve in nonpolar solvent
compounds with charges dissolve in?
polar covalent compounds
can dissolve together or in each other
can dissolve itself
what is partially ionized

concentrations of H+ and OH- are bother the same in?
when water is ionized it only releases?
either H+ OR OH-
in water having more of one than the other creates either an ?
acid or base
