3. enzyme that helps digest fats by breaking them down into fatty acids and glycerol
4. enzyme that breaks down lactose, the sugar found in milk
7. substances that speed up chemical reactions without being consumed
10. small, single units that can join together to form larger molecules (polymers)
11. process where substances are transformed into different substances
12. measure of acidity or alkalinity; can influence enzyme function
13. biological catalyst that speeds up chemical reactions in living organisms
14. fats, oils, and steroids; hydrophobic substances
