molecules Correct Answers allosteric
4 types of Macromolecules Correct Answers proteins, nucleic
acids, carbohydrates, and lipids
6 kingdoms Correct Answers Archaea, bacteria, Protista, Fungi,
Plantae, Animalia
7 Chemical Reactions•The starting molecules of a chemical
reaction are called the ___ or ____ Correct Answers reactants
or, substrates
a form of enzyme inhibition where the product of a reaction acts
as a repressor Correct Answers Feedback inhibition
A life defining property must be __________ to living things.
Correct Answers Exclusive. Living things always organized and
structured
a molecule of water is added to break the covalent bond between
the
monomers. This process is called? Correct Answers Hydrolysis
activators Correct Answers change the shape of the enzyme so
that it can bind the substrate
,Adhesion Correct Answers An attraction between molecules to
polar molecules
Ex. Capillary action
All chemical reactions require an initial input of energy called
the _______ Correct Answers activation energy
All the work carried out by living organisms involves the
______ of potential energy to kinetic energy Correct Answers
transformation
Are liquid lipids saturated or unsaturated? Correct Answers
unsaturated. these are lipds with less HC+ than maximum.
Double bonds: C only has one H+ attached.
funfact! people on the coast of southern italy eat lots of
unsaturated fats/ oils and it is thought to keep their bloodstream
lubricated
Are solid lipids saturated or unsaturated? Correct Answers
saturated lipids with the maximum number of HC+ possible.
single bonds: each C is attached to two other H+
atom Correct Answers a basic unit of matter that cannot be
broken down by normal chemical reactions
Atomic Mass Correct Answers the number of protons + the
number of neutrons in the nucleus
, Atomic Number Correct Answers the number of protons in the
nucleus of an atom. this is the identity of the atom.
ATP Correct Answers adenosine triphosphate - is the energy
currency of the cell
Bacteria Correct Answers Its own domain and Kingdom
single-celled, microscopic organisms
Base Correct Answers high pH number low number of H+,
Biology is.. Correct Answers the study of living organisms and
their interactions with one another and their environments. Very
Broad and Diverse
Blind Study Correct Answers participants do not know if they
are being given treatment/ are unaware of the experiment
Buffer Correct Answers Chemical substance that takes up or
releases hydrogen ions.
Organisms use buffers to minimize pH disturbances
Carbohydrates Correct Answers are monomers that
make up the structural framework of cells and play a critical role
in energy storage.
1:2:1 C,H,O ratio
carbohydrates Correct Answers sugars. rings structures. these
are monomers for polymer chains called monosaccharides.
