What are biomolecules?
Molecules of life
What are macromolecules?
They are large molecules composed of made of covalently bonded atoms
What is a polymer
a long molecule made of similar and repeated building blocks called monomers
Name the 3 classes of life organic molecules which are polymers
Carbohydrates
Protein
Nucleic acids
Which organic molecule is not a polymer
Lipids
How do monomers join to form polymers
Condensation reactions called dehydration reactions
How do polymers disassemble to monomers
Hydrolysis
Where do all living things get energy and nutrients
Food in the form of biomolecules
What is a polymer most simar too
a chain
what is a monomer most similar too
a link
What does it mean when biomolecules are digested
this means that they are broken apart to obtain the building blocks (monomers) and the energy inside them
What does it mean when a biomolecule is synthesized
the biomolecule is built by the cells to complete certain tasks and store energy for later use
Which are carbohydrates also known as
Saccharides
What are the 3 saccharides in carbohydrates
Monosaccharides
Disaccharide
polysaccharide
How is sugar produced
by plant during photosynthesis
What is the primary source of energy for most organisms
Sugar
Equation for photosynthesis
6H2O + 6CO2 + energy > C6H12O6 + 6O2
What are cell walls made of
Cellulose which is made of complex carbohydrates. Cellulose is very strong and rigid.
What are lipids made of
Fats, Cholesterol and phospholipids
What is fat made of
A glycerol molecule
3 fatty acids
What can lipids be used for
to store large amounts of energy. Extra energy in the body
Between lipids and carbohydrates which has more energy gram for gram
Carbohydrates
what are call membranes made of
phospholipids
what ae nucleic acids made of
nucleotides
What re the 3 parts of a nucleotide
a phosphate group
deoxyribose sugar
1 of 4 nitrogen base
function of nucleic acid
store genetic information used to make protein
2 main type
