Proteins
- The monomer subunits of proteins are amino acids.
Cell Membranes
- Phospholipids are a component of cell membranes.
Nucleic Acids
- The function of nucleic acids is to store and transmit genetic information.
- Adenine pairs with thymine in DNA.
Cells
- The smallest, basic unit of life is the cell.
- There are approximately 37.2 trillion cells in the human body.
Characteristics of Life
- The characteristics of life include organization, metabolism, homeostasis, growth and development, reproduction, response to stimuli, and evolution.
Metabolism
- Metabolism is the sum of all chemical reactions that occur in an organism.
