Life Science Chapter3 - Summary Notes

The Chemicals of Life

• Cells, the tiny sacks that have all the pieces for life, are made from lots of little chemical pieces.
• Proteins make up things like hair and feathers and muscle.
• Other proteins are nature’s little nano-machines called enzymes that build our bodies, so the bread you eat today can become part of your ear tomorrow.
• Carbohydrates are sugars that are used for the cells’ rapid energy supply but carbohydrates also form things like noses and eardrums.
• Lipids are oils for things like stored energy and barriers to hold the cell together.
• ATP (adenosine triphosphate) transfers the energy in carbohydrates and lipids into a form that can power the cell’s actvities.
• Nucleic acids make the backbone of DNA, which is the blueprint of life.
