Exam 8: Harvesting Energy: Glycolysis and Cellular Respiration

In the absence of oxygen, suppose a single yeast cell undergoes fermentation and uses 100 molecules of glucose. How many molecules of ATP will be generated?

Which of the following processes involves ATP-synthesizing enzymes that are associated with hydrogen ion channels?

In the Krebs cycle, NADH molecules are oxidized as one chemical compound is converted to another, except during the conversion of:

We breathe more heavily during exercise because our cells:

Two possible end products of fermentation are ________ (as is produced by our muscle cells under anaerobic conditions)and ________ (as is produced by yeast under anaerobic conditions).

The anaerobic breakdown of glucose is called:

The main function of cellular respiration is to produce:

Chemiosmosis links a hydrogen ion gradient to the production of ATP. True or False?

The step in aerobic respiration that produces the most ATP per molecule of glucose is:

The products of glycolysis are:

During which of the following processes is CO2 produced?

How does one account for the bubbles in a glass of beer or champagne?

Briefly compare and contrast the processes of cellular respiration and photosynthesis.

The process of fermentation is energetically more efficient than cellular respiration. True or False?

At the end of glycolysis, the original carbons of the glucose molecule form:

The term "chemiosmosis" is associated with which process?

What is the final electron acceptor in cellular respiration?

If only one molecule of pyruvate (instead of two)were produced per glucose molecule metabolized in glycolysis, then which of the following would be produced after glycolysis and before the electron transport chain?

Briefly describe the three main steps of aerobic glucose metabolism.

________ is the process by which hydrogen ions move via a concentration gradient through ATP-synthesizing enzymes, resulting in the production of ATP.
