True/False and fix the statement if false!
Carbs have the highest amount of energy out of all the macromolecules.
False, they are the main source of energy and are short-term energy sources
In the iPod lab, how did we test for lipids?
Examined whether a grease stain was produced on brown paper
What are the components of a nucleotide?

Explain how organic and inorganic compounds differ
Organic: contains carbon and made/found in living things
Ex. glucose
Inorganic: not made by living things but needed by them
Ex. water,calcium

What is the smallest unit of a carbohydrate?
monosaccharide
True/False. Fix if false!
Lipids are found in cell membranes and make the membrane polar or hydrophilic
False. While lipids are found in cell membranes, the cell membrane is nonpolar or hydrophobic (water fearing).
Ex. Oil and water do not mix
DOUBLE JEOPARDY

In the Diagnosis Episode, how did they find out that the patient had cpt2 disease.
They sequences her genome or DNA (composed of nucleic acids).
What is the difference between dehydration synthesis and hydrolysis?
dehydration synthesis: releasing water to build an organic compound
hydrolysis: adding water to break apart an organic compound
