Generation of ATP

II. BACTERIAL GROWTH AND MICROBIAL METABOLISM

C. Energy Conversion in Microorganisms

3. Mechanisms for Generating ATP

LEARNING OBJECTIVES FOR THIS SECTION

Depending on the type of organism, cells transfer energy and generate ATP by:

1. photophosphorylation,

2. substrate-level phosphorylation, and/or

3. oxidative phosphorylation.

(Phosphorylation (def) refers to the attachment of a phosphate group to a molecule.)
