ribonucleic acid
MRNA and TRNA
what is RNA? single stranded
shorter
AU CG
what are biological molecules made and used by living organisms eg.
molecules? lipids, carbs, DNA, AT, water, inorganic ions
-energy source (respiration)
what are the functions of
-energy store (starch and glycogen)
carbohydrates?
-structure (cellulose)
1 adenosine 3 phosphates
ADP and energy= ATP
condensation reaction using ATP synthase
ATP structure? carries energy in bonds
hydrolysis breaks down into ADP and energy using
ATP hydrolase
releases energy from phosphate group bonds
what are the building monosaccharides
blocks of carbohydrates
called?
, immediate release, only need to break one bond
why is ATP a good source
releases small amounts of energy at a time,
of energy?
manageable
examples of glucose, fructose, galactose
monosaccharides
protein synthesis
organelle synthesis
dna replication
mitosis
uses of ATP?
active transport
metabolic reactions
movement
homeostasis
formula for c6h12o6 -same formula but arranged differently
monosaccharides?
acts as a habitat for organisms
role of water in biology? make up cytoplasm, tissue fluid, blood, xylem and
phloem
dipolar
partially positive hydrogen partially negative oxygen
water properties?
so separate water molecules form hydrogen bonds
with eachother
difference between alpha on carbon 1, alpha glucose has an OH group on the
and beta glucose? bottom. beta glucose has it at the top.
how are monosaccharides condensation reaction between 2 OH groups
joined together?
