Exergonic reactions ________.

Enzymes that are only produced when substrate is present are termed ________.

Fermentation ________.

Building block molecules for biosynthetic pathways come from the cell's catabolic pathways and from the environment.

The fermentation process always produces alcohol as at least one of its products.

As the electron transport carriers shuttle electrons, they actively pump ________ into the outer membrane compartment setting up a concentration gradient called the proton motive force.

Each NADH that enters the electron transport system gives rise to a maximum of ________ ATP.

When glucose is broken down by glycolysis during bacterial fermentation, how many ATP are generated?

The carrier molecules in the electron transport chain that have a tightly bound metal atom responsible for accepting and donating electrons are ________.

In a bacterial cell, the genes that code for enzymes that catalyze the hydrolysis of an unusual carbohydrate source would be turned off unless that carbohydrate was the only fuel source available in the media, in which case ________.

Most electron carriers are ________.

The RN instructs the patient that although bacterial cells can also undergo aerobic respiration, they differ from eukaryotic cells in that ________.

Denaturing an apoenzyme will destroy the three-dimensional shape of the protein, making it nonfunctional.
