Levels of Organization
Homeostasis: Body’s maintenance of a stable internal environment
Metabolism : all the chemical reactions occurring in the body.

Carbohydrates
Sugars
Provide both energy and structure
There are 3 types:◦Monosaccharide
1 sugar – quick energy
◦Disaccharide 2 sugars – short storage
◦Polysaccharide many sugars –long term energy storage
![Page 11: Unit 1 Chapters 1 and 2](https://reader035.vdocuments.net/reader035/viewer/2022062304/56813466550346895d9b4c4c/html5/thumbnails/11.jpg)
Lipids
Water insoluble ◦Triglycerides: insulation and long-term
energy ◦Phospholipids: make up cell membrane◦Steroids: cell signaling
Includes androgens and estrogens.
◦Waxes: prevent water loss, protect

Proteins
Versatile in function Prevalent

Nucleic Acids: DNA and RNA
Made up of nucleotides phosphate molecule, nitrogenous base, and 5-carbon sugar
Several types of nucleic acids, including:◦ DNA: deoxyribonucleic acid, double stranded helix◦ RNA: ribonucleic acid that is used for making proteins,
single stranded, includes uracil instead of thymine◦ ATP: adenosine triphosphate, provides energy for cell
