Down
- 1. type of mixture in which all components are evenly distributed
- 2. Organic compounds with an amino group (-NH2) on one end and a carboxyl group (-COOH) on the other end.
- 4. During non-competitive inhibition, molecules do not sit in the active site but will attach to an _______.
- 5. tendency of water to rise in a thin tube
- 6. chemical reactions that absorb energy (will NOT occur without an input of energy)
