An Overview of Photosynthesis
Photosynthesis is the process of using sunlight to produce carbohydrate. This process
requires sunlight, carbon dioxide, and water, and produces oxygen as a by-product. The
overall reaction wh

Hydrogen bonds between the carbonyl group of one amino acid and the amino
group of another form a proteins secondary structure.
A polypeptide must bend to allow this hydrogen bonding, forming:

Cell-Cell Interactions and Cell Signaling
Quorum Sensing in Bacteria
Even unicellular organisms live together and communicate with one another.
Cell-cell communication in bacteria is called quorum sensing.
Bacteria release sp

The Location of Photosystem I and Photosystem II
Photosystem II is much more abundant in the interior, stacked membranes of grana.
Photosystem I and ATP synthase are much more common in the exterior, unstacked

Identical receptors in diverse cells and tissues allow long-distance signals to
coordinate the activities of cells throughout a multicellular organism.
Signal receptors are proteins that change their shape or

The Role of Carotenoids and Other Accessory Pigments
Carotenoids are accessory pigments that absorb light and pass the energy on to
Carotenoids are classified into two groups carotenes and xanthophylls.
Chapter 4 Notes
A nucleic acid is a polymer of nucleotide monomers.
Nucleotides are each composed of a phosphate group, a sugar, and a nitrogenous base.
The sugar is ribose in ribonucleotides and deoxyribose in deoxyribonucleotides.
There are two group

Electrons Participate in Redox Reactions
Electrons in the electron transport chain participate in redox reactions and are gradually
stepped down in potential energy.
These redox reactions result in protons being pumped fr
