study guide elaborated correctly.
hydrogen bonds - Answer weak electrostatic intermolecular bonds
formed between polar molecules containing at least one hydrogen
atom
monomer - Answer small molecule that is a single unit of a larger
molecule called a polymer
polymer - Answer long chain molecule made up of many smaller
repeating monomer units joined together by chemical bonds
,macromolecule - Answer very large molecule formed by polymerisation
starch - Answer energy store in plants made of amylose and
amylopectin. Insoluble and compact and can be broken down rapidly to
release glucose
sucrose - Answer sweet tasting disaccharide formed by the joining of a
glucose and fructose by a glycosidic bond
glucose - Answer hexose sugar
triose sugar - Answer sugar with 3 carbon atoms and important in
mitochondria
pentose sugar - Answer sugar with 5 carbon atoms and important in
nucleic acid
ribose - Answer pentose sugar that makes up part of the structure of
RNA
deoxyribose - Answer pentose sugar that makes up part of the
structure of DNA
, deoxyribonucleic acid - Answer nucleic acid that acts as the genetic
material in many organisms
ribonucleic acid - Answer nucleic acid which can act as the genetic
material in some organisms and is involved in protein synthesis
hexose sugar - Answer sugar with 6 carbon atoms and taste sweet
isomers - Answer molecules that have the same chemical formula, but
different molecular structures
nitrate ions (NO3)- - Answer needed in plants for formation of amino
acids and DNA
phosphate ions (PO4)3- - Answer forms ATP, ADP, DNA and RNA
calcium ions (Ca)2+ - Answer forms calcium pectate for middle lamella
between cell walls
magnesium ions (Mg)2+ - Answer produces chlorophyll in plants
water- polar solvent - Answer ionic substances dissolve in it and can
carry other substances
