The movement of water from an area of high concentration to low, across a partially permeable membrane
(a)
What is the definition for Monomer?
a molecule that can be bonded to other identical molecules to form a polymer.
a substance that takes part in and undergoes change during a reaction.
the species formed from chemical reactions.
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
What is the definition for Protein?
large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
used to specify the acidity or basicity of an aqueous solution.
a molecule that can be bonded to other identical molecules to form a polymer.
What is the definition for Nucleic Acid
small molecules that are the building blocks of proteins.
large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
What is the definition of Amino Acid?
large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
any of the class of sugars that cannot be hydrolyzed to give a simpler sugar.
a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
small molecules that are the building blocks of proteins.
The end product of respiration, used as the universal energy carrier molecule
(a)
Movement against the concentration gradient, requiring ATP
(a)
The maintenance of a constant internal evironment, despite changes in the external conditions
(a)

(a)
The first stage in a cell signalling pathway
Response
stimulus
Transmission
reception
Molecule in the cell membrane which recieves signal molecule
(a)
The signalling cascade is triggered by the (a) protein
Which factor does not affect the rate of diffusion?
Temperature
Concentration Gradient
Size of molecule
Shape of molecule
The surface area: volume ratio decreases as the size of the object (a)
diffusion of a substance
through transport proteins in a cell membrane; the
proteins provide hydrophilic areas that allow the
molecules or ions to pass through the membrane which
would otherwise be less permeable to them.
(a)
