Bioenergetics and metabolism
Why does a cell need energy?
To maintain order, synthesize macromolecules, movement
For energetically unfavorable reactions to proceed
What is the source of cellular energy?
STUDY GUIDE: MEMBRANES
A) Definition: semi-permiable phospholipid bilayer/protein complex
1) Which organelles are membrane bound?
2) Which macromolecular complexes in eukaryotic cells are not?
B) General Functions (at the level of a single cell):

2016 Study Guide for Chapter 2
There is quite a lot of interesting information in Chapter 2. The sections labeled Human
Perspective are interesting, but you will not be tested on any of this information.
In addition p. 30-52 contain information on the 20

Acetylcholine Gated Na+ Channel
Consider the types of cells that may use this channel. Would you expect to
find this channel in all cells?
Faciliated Channel -> Things move through via faciliatated diffusion.
Things still move down the conc. gradient
A lot faster than passive diffusion channels
Co-Transport -> The driving force can depend on the channel itself
Symport -> Two subs. movi
PC - Neutral (likely facing outside)
PE - Neutral (likely facing inside)
PS - Negative (likely facing inside)
PI - Negative (likely facing inside)
Therefore, the inside of the cell wall has a slight negative charge (relative to the outside)
