Building Blocks of
LifeTEKS 7.6A
identify that organic
compounds contain carbon
and other elements such as hydrogen,
oxygen, phosphorus, nitrogen or
sulfur
All living
things are
made up of
cellscells.
But what makes up
cells?
Amazingly, cells are made up almost entirely of the elements carbon, hydrogen, oxygen, nitrogen, phosphorus & sulfur.
These elements make up four basic types of organic molecules: carbohydrates, lipids, proteins & nucleic acids.
Molecules are the smallest particle of a substance that keeps the chemical & physical properties of that substance & are composed of two or more atoms.
Naturally occurring organic
molecules are made by
plants or animals.
They are built into long chains of
smaller units… like adding beads to a
bracelet or cars to a train.
All organic
compound
contain the
element carbon.
Carbohydrates
•made up of carbon, hydrogen & oxygen
•sugars & starches are common carbohydrates that provide energy & support to cells
Lipids•made up of carbon, hydrogen & oxygen
•fats, oils & waxes are common lipids that store energy & provide protection to cells
Proteins
•made up of carbon, hydrogen, oxygen, nitrogen & sometimes sulfur
•proteins
provide
structure to
muscles, skin,
hair, nails & the
outside
membrane of
cells
Nucleic acids•made up of carbon, hydrogen, oxygen, nitrogen, phosphorus & sometimes sulfur
•two nucleic acids
with all of the
genetic information
to control & build
cells are
deoxyribonucleic
acid (DNA) &
ribonucleic acid
(RNA)
