Exam 2 Study Guide
The functions of many proteins involve the reversible binding of other molecules.
A molecule bound reversibly by a protein is called a ligand.
A ligand binds at a site on the protein called the binding site.
Binding site is comp
We continue our discussion of protein structure by considering the structure of

Lipid Variation Notes
Lipids" defined based on a common physical property - they're insoluble in water and
soluble in organic solvents
Two of the major functions of lipids:

Twin Defect Notes
Splitting of the zygote usually occurs at the early blastocyst stage.
The inner cell mass splits into two separate groups of cells within the same blastocyst
cavity (Fig. 8.19B).
The two embryos have a common placenta and a common chorio
The fluid (a) absorbs jolts, (b) prevents adherence of the embryo to the amnion, and (c)
allows for fetal movements.
The volume of amniotic fluid is replaced every 3 hours. From the beginning of the fifth
month, the fetus swallows its own amnio
Lecture 15 Notes
When ligand-gated ion channels open, the membrane potential changes depending
on which ion channel is open.
Opening Na+ or Ca2+ channels results in a graded depolarization called an
excitatory postsynaptic potential (EPSP).
Opening K+ or
