Weak or strong bond?
Covalent, strong
What is electronegativity
the pull of an atom for -e
How does electronegativity effect atoms
the more strongly an atom attracts the electrons in its bonds the larger is electronegativity
When do electrons have a low level of potential energy?
When they are associated with a more electronegative atom
What happens to a macromolecule in a hydrolysis reaction ?
They form smaller molecules that can be absorbed by cells then further broken down to release energy
What are the four categories of organic macromolecules ?
Carbohydrates, Lipids, Proteins, nucleic acids
