Helminthes – unicellular
Virus capsids are made from subunits called
In the cell, energy released by electrons is often used to phosphorylate:
Viruses acquire envelopes around their nucleocapsids during:

Formation of peptide bonds between amino acids to build a polypeptide would be called:
Filamentous fungi are called:
Host range is limited by:
Type of host cell receptors on cell membrane
Algae and protozoa
The group of protozoa that are not mobile are the:
Bread molds are identified and classified based on:
They form zygospores
The group of protozoa that have flagella are the:
Helical and icosahedral are terms used to describe the shapes of a virus':
When microbes in close nutritional relationship and one benefits but the other does not is called:
The most likely place where an exoenzyme participates in a chemical reaction is:
Outside the cell
As the electron transport carriers shuttle electrons, they actively pump ________ into the compartment setting up a concentration gradient called the proton motive force.

Plants and fungi
Protozoa and algae
All of the chemical reactions of the cell are called:
Algae use sunlight to fuel glucose synthesis. They can create glucose from inorganic c02
Nonsulfur bacteria capture sun energy to build their required compounds. They feed off of other organisms to acquire their carbon.
Parasites and saprobes are subsets of which category of organisms?
Based on what you observe, how would you describe the structure of this virus?
(Really dark picture) Enveloped icosahedral
What type of cell would you predict this virus would infect?
What can you predict about how this virus exits the host cell?
Budding out of the host cell
A yeast cell requires acidic pH in order to grow, The action of bacteria in milk lowers the pH to the required pH for the yeast. Without the action of the bacteria the yeast would not be able to grow. The bacteria can also survive in this pH. what relationship?
Your stomach produces acid that destroys many bacteria found in food. When you consume contaminated food, the stomach acid kills and keeps you from getting sick?
Certain fungi grow on the roots of plants. The fungi produce nutrients the plant needs in order to grow. The fungi are protected by the roots against bacteria that could consume them?
