- Chapter Name:
- Chapter 1: Living in a Microbial World
- Description:
- Neutrophils are white blood cells that hunt and kill bacteria. In this spread, a neutrophil is seen in the midst of red blood cells. Staphylococcus aureus bacteria have been added. The small clump of bacteria release a ...

- Chapter Name:
- Chapter 2: The Chemistry of Life
- Description:
- Molecules in solution undergo random thermal movements and may encounter each other frequently if the concentration is sufficiently high. If two molecules with poorly matched surfaces collide, only a few weak bonds will form ...

- Chapter Name:
- Chapter 2: The Chemistry of Life
- Description:
- A glucose molecule is a six-carbon sugar, consisting of a total of 24 atoms.
It is very polar due to its hydroxyl groups to which water molecules can hydrogen bond.
By convention, carbon atoms are shown in gray, oxygen ...

- Chapter Name:
- Chapter 2: The Chemistry of Life
- Description:
- Phospholipids contain a head group, choline in this case, that is attached via a phosphate group to a 3-carbon glycerol backbone. Two fatty acid tails are attached to the remaining two carbons of the glycerol.
The head ...

- Chapter Name:
- Chapter 3: The Cell: Where Life Begins
- Description:
- Many species of bacteria propel themselves through their environment by spinning helical motorized flagella. Rhodobacter cells have one flagellum each, whereas E. coli cells have multiple flagella that rotate in ...

- Chapter Name:
- Chapter 3: The Cell: Where Life Begins
- Description:
- In a lipid bilayer, lipids arrange themselves so that their polar head groups are exposed to water and their hydrophobic tails are sandwiched in the middle.

- Chapter Name:
- Chapter 3: The Cell: Where Life Begins
- Description:
- Phagocytosis allows cells to take up large particles, such as these yeast cells that are being engulfed by the slime mold Dictyostelium.
-
- Chapter Name:
- Chapter 4: A Field Guide to Microorganisms
- Description:
- The biosynthesis of double-stranded DNA virus takes place in the nucleus of the host cell and uses the host cell’s replication machinery.
After entering the host cell, the virion uncoats in the cytoplasm, releasing the ...

- Chapter Name:
- Chapter 4: A Field Guide to Microorganisms
- Description:
- Single-stranded RNA viruses contain either a positive RNA strand or a negative RNA strand. In this animation, we will look at the biosynthesis of a negative RNA strand virus.
After entering the host cell, the virion uncoats ...
