Chemical compounds in cells
Carbohydrates
energy filled organic compounds
made of hydrogena and oxygen
starches are also called complex carbohydrates
The cellulose in a cell walls of plants is a type of carbohydrate
Lipids
Oils,fats and waxes are lipids
Lipids contain rich organic energy compounds
lipids are a energy storage for cells
cell membranes are made of mostly lipids
Elements and compounds
Compounds
Two or more elements combined to make a compounds
The smallest unit in compounds is a molecule
An example of a compound is 2 hydrogen atoms and one oxygen atom to make water
organic and inorganic compounds
Important groups of organic compounds in living things are carbohydrates, proteins lipids and nucleic acids
most compounds that have carbon in them are called organic compounds
Elements
Some elements are nitrogen and oxygen is called a atom
The smallest part of an element
A element is any substance that cannot break down into simpeler substances
air is made of elements and compound some gases in the air are nitrogen, oxygen and carbon dioxide
Proteins
Structure of proteins
Small molecules are called amino acids
cells combine the 20 different amino acids to make thousands of different proteins
The order the amino acids are put together can make different proteins
Are large organic molecules made out hydrogen, carbon, nitrogen and oxygen
Functions of proteins
Proteins form parts of the cell membrane ask make up organelles within the cell
enzymes are a different type of protein that accelerate chemical reaction in living organisms
Enzymes in your saliva speed up the digestion of food
Nucleic acids
RNA
Found in cytoplasm and nucleus
Helps produce proteins
Nucleic acids
Organic molecules
instructs the cell to carry out the functions of life
DNA
Genetic material carries information about an organism that is passed to an offspring
Water and living things
most chemical reactions in cells couldn't happen without water
water also helps cells keep there form
