What is the difference between organic and inorganic molecules?

Organic-- always contains carbon, was part of a living organism



Inorganic--can contain carbon, never was a part of a living organism

500

Enzymes, Transport, and Regulation are functions of what kind of macromolecule?

Proteins

500
Describe the polarity of a water molecule, and its effect on other water molecules.
Hydrogen atoms are slightly positive and Oxygen atoms are slightly negative; this causes hydrogen bonding which makes water cohesive.
