What are the two compnents of a lipid?
Glycerol
Fatty Acid
What is the name of the process that combines two compoents of a biological molecule? What is the name of the process that splits them apart?
combines = dehydration synthesis
splits = hydrolysis
What are the 4 levels of protein structure? Do all proteins reach all of these levels?
Primary, Secondary, Tertiary, Quaternary.
Not all proteins reach quaternary structure!
Drawn the hydrogen bond that occurs between amino acids in the secondary strcuture of a protein.

What is the function of the smooth and rough endoplasmic reticulum? How can you tell the difference between the two?
The rough ER has ribosomes on its surface. It makes and folds proteins. The smooth ER makes lipids.
