Vocabulary:

Molecule: group of 2 or more atoms held together

Energy: we make it by eating food 

ATP: made by cellular respiration and releases energy when the high energy bonds are broken 

DNA: contains genetic information for development and functioning of an organism 

RNA: help convert the information contained in the cell's DNA into functional gene products like proteins.

Monomer: smallest unit of larger molecules called polymers 

Dehydration synthesis: combines two or more monomers to make a polymer by making water as a product 

Hydrogen Bonding: slightly positive hydrogen atom with a slightly negative atom to make a easily broken bond 

Glycosidic Bond: a bond that joins disaccharides 

Phosphodiester Bond: bonds that form between sugar and phosphate to form the backbone of nucleic acids

Cellular Respiration: breaking down of a sugar called glucose to make energy 

What are macromolecules? Huge molecules that are made up of smaller molecules, bonded by the chemical reaction of dehydration synthesis 

There are 4 types:

Lipids

Carbohydrates 

Proteins 

Nucleic Acids 

All of these are important for the function of our body!!

Lipid's function: help store energy, making cell membranes, protect and insulate the body

Healthy: unsaturated fats

is liquid at room temperature and have hydrocarbon molecules with double/triple bonds 

Not healthy: saturated fats, is solid at room temperature that lacks unsaturated links between Carbon atoms

They are made up of monomers (triglycerides) which give you energy for long periods of time

A triglyceride=free fatty acid+ glycerol 

which means they will not mix with water to break down --> the long term energy

Carbs: gives us energy for short periods of time which makes it the most accessible and used source of energy for us

The polymer of a carbohydrate is a polysaccharide, which is made out of monosaccharides (bonding to make Glycosidic Bonds)

Since carbohydrates have sugar, they are broken down by CELLULAR RESPIRATION to make ATP, which we use as energy Glycosidic Bond

I get so much energy after eating cookies!!
