levels of organisation - ANSWER atoms, cells, tissue, organ level, organ
system
chemical bonds - ANSWER allow elements to combine and compounds to
form
all bonds affect mc shape/form- affect mc function
similar chemical shapes - ANSWER mimicking effect
mc of similar shapes have similar functions
synthesis - ANSWER combining atoms to form larger, more complex
molecules
A + B = AB
anabolic - energy is taken in
decomposition - ANSWER breaking apart molecules
AB = A + B
catabolic - energy released
exchange reaction - ANSWER bonds made/broken to exchange parts
AB + C = AC + B
AB + CD = AD + BC
anabolic - ANSWER energy taken in
, catabolic - ANSWER energy released
factors that influence the rate of reaction - ANSWER temperature
catalyst
concentration
pressure
particle size
pH
mixtures - ANSWER two or more components physically intermixed and not
chemically bonded
ex: blood cells
solution - ANSWER homogeneous (same) mixture
ex: NaCl, KCl
major elements of the human body - ANSWER carbon, hydrogen, oxygen, and
nitrogen
organic compounds - ANSWER contain carbon
molecules unique to living systems contain carbon
include 4 molecular biochemical polymers carbs, lipids, proteins, nucleic acids)
covalently bonded (share electrons) and usually large
inorganic compounds - ANSWER no carbon
ex: water, salts, many acids and bases
salts (NaCl, KCl, Na2SO4) - ANSWER inorganic compounds dissolve in
water
contain ionic cations other than hydrogen and anions other than OH-
electrolytes - conduct electrical current in solution
electrolytes - ANSWER conduct electrical current in solution
