Term
A microorganism utilizes glucose as a nutrient and is able to oxidize it to water and carbon dioxide. It is an example of what metabolic group?
Definition
Chemoorganotroph
Term
The energy required to drive endergonic reactions within the cell most likely comes from what molecule?
Definition
ATP
Term

Some fermentative bacteria produce lactic acid from pyruvate. What is the major reasons this step in fermentation?

 

Definition
It generates oxidized NAD molecules, needed to maintain the anaerobic glycolysis pathway.
Term
At the end of process by which an enzyme converts a substrate to product, what is the status of the enzyme?
Definition
It has reverted to its original form and can interact with a new substrate molecule.
Term
From where do the hydrogen ions that create the proton motive force used to produce ATP molecules come?
Definition
Nutrients such as glucose.
Term

Pasteur's experiment using swan-necked flasks was designed to do what?

 

Definition
