week 3 Flashcards
during ionisation, water molecules disrupt the ionic bonds of a solute & a mixture of ions is produced . this ion is called?
electrolytes
if a molecule has 2 equal and opposite electrically charged poles separated by a small distance it is called?
dipolar
in an aqueous solution cations move toward ?
anions
in an aqueous solution sodium moves towards?
chloride
a solution with equal no. of hydrogen ions and hydroxide ion is ?
neutral
is a pH of 6 least or more acidic?
least
a substance with a pH 7+ is called
alkaline
an important buffer in the body is a- NaCl b-NaOH c-HCL d-NaHCO3
d
in the body an inorganic compound serves as what ?
buffer
hydrophilic moelecules associate with what molecule?
water
an excess of H ions in the body fluids can do what ? a-break down chemical bonds b-change shape or large complex molecules c-distrupt tissue function d- all of above
d
an inorganic compound when place in water, dissociates 99% forming H ions and anions. what type of acid would it be ?
strong
an acid has a pH level of what?
less than 7
__ is a product of the reaction of an aicd with a base
salt
if solution A has a pH of 7.48 and 7.39 which one has a higher concentration og H ions
solution b
a common buffer found in extracellular fluid a-glucose b-bicarbonate ion c-sodium ion
b
what is the normal range of pH for blood
7.35-7.45
glucose is the only source of energy for this organ
brain
a complex carb that we cannot digest
cellulose
this hormone increases the transport of gluose in cells
insulin
the structural lipid molecule that is the chief component of cell membrane
phospholipid
used universally by all cells in the body
glucose
an important component of cell membranes and precursor of sex hormones
cholesterol
glucose + glucose =
maltose
20 carbon fatty acids found in cell membrane
eicosanoids
glucose + fructose =
sucrose
contained by molecules unique to living systems
carbon
the fluid portion of blood
plasma
excess H+ in the body fluid (low pH)
acidosis
solutions that have equal H+ & OH - concentration
neutral
an inorganic compounds that contain cations other than H+ and anions other then OH-
salts
excess OH- in fluid ( high pH)
alkalosis
the concentration of H+ ( H ions) in a solution
pH
tissue that carries less water than muscle tissue
adipose
the fluid in the spaces between our cells
interstitial
humans that have 73% water
infants
