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

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

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

Phagocytosis is a mechanism that happens in various unicellular organisms when cells
feed and enclose their nutrients in membrane-bo
Ch 7 Summary
7.1 Energy balance considers energy intake and energy output. Negative energy balance occurs
when energy output surpasses energy intake, resulting in weight loss. Positive energy balance
occurs when calorie intake is greater than output, resu
Ch 6 Summary
6.1 Amino acids, the building blocks of proteins, contain a very usable form of nitrogen for
humans. Of the 20 common types of amino acids found in food, nine must be consumed in food
(essential) and the rest can be synthesized by the body (n

5.1 Lipids are a group of compounds that do not dissolve in water. Fatty acids are the simplest
form of lipid. There are three fatty acids on every triglyceride, the most common type of lipid
found in the body and foods. Phospholipids and ste

4.1. Carbohydrates are created in plants through photosynthesis. They are our main fuel source
for body cells. Some carbohydrates promote health more than others.
