Biomolecules Any molecule present in a living organism, often carbon-based (organic).
Atomic mass Number of protons plus neutrons.
Valence Electrons Electrons in outer electron shell. Unfilled outer shell causes atom to become unstable. Determines bonding potential.
Water & Hydrogen bonds Polar molecule, Good solvent (substances dissolve in it), Can form strong hydrogen bonds, Polar molecules (covalent bonds) may dissolve in water and are called hydrophilic, Nonpolar molecules do not dissolve in water and are called hydrophobic
Ionic bonds one atom gives electrons to another so that both have filled valence shells. Weaker than covalent bonds.
electron donor becomes positively charged; the atom now called a cation.
What is the breakdown of our Nervous system? Central Nervous System Peripheral Nervous System Sensory (Afferent) nerves Motor (efferent) nerves Somatic Nervesous system Autonomic Nervous system (this makes up the Sympathetic & the Parasympathetic_
