Exam 2 Microbiology

Front

What is the primary source of energy for most bacteria?

Back

Glucose

Front

What do chemoautotrophic bacteria use as energy and carbon sources?

Back

Inorganic compounds as both energy and carbon sources.

Front

What is the final electron acceptor in anaerobic respiration?

Back

Nitrate or sulfate.

Front

What are obligate anaerobes?

Back

Bacteria that cannot tolerate oxygen and must grow in oxygen-free environments.

Front

What is an example of a virus with icosahedral symmetry?

Back

Adenovirus.

Front

Define chemoautotrophy.

Back

A metabolic process where organisms obtain energy from inorganic compounds and use carbon dioxide as a carbon source.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration uses oxygen as the final electron acceptor, while anaerobic respiration uses other molecules like nitrate or sulfate.

Front

What are facultative anaerobes?

Back

Bacteria that can survive with or without oxygen.

Front

What is the role of glucose in bacterial metabolism?

Back

Glucose serves as a primary energy source for many bacteria.

Front

What is the significance of the final electron acceptor in respiration?

Back

It determines whether the process is aerobic or anaerobic and affects energy yield.
