What is the oxidative phosphorylation function of the ATP proton pump?

Which of the following statements is an accurate description of what happens in electron transport?

Dividing bacterial cells require large amounts of energy in the form of ATP. Which of the following processes results in the greatest production of ATP?

Why is oxygen necessary in aerobic cellular respiration?

The proton motive force is:

How does extreme temperature affect mesophilic proteins?

In allosteric feedback inhibition, which molecule ultimately inactivates the FIRST enzyme in a series of reactions involving many enzymes in a cascade?

Some of the drugs used to treat HIV patients are competitive inhibitors of the HIV reverse transcriptase enzyme. Unfortunately, the high mutation rate of HIV means that the virus rapidly acquires mutations with amino acid changes that make them resistant to competitive inhibitors. If these drugs are competative inhibitors, where in the reverse transcriptase enzyme would such an amino acid change most likely occur in drug resistant viruses?

Enzymes are capable of increasing the rate of a chemical reaction through which of the following processes?

Reducing enzyme activity by blocking its active sites is called:

Which metabolic pathway or process is common to both aerobic oxidation and fermentation of sugar?

Microbial fermentation can be detected in laboratory identification by observing a change in:

What does NADH transfer?

NAD+, FAD, and NADP+ are all examples of:

During the glycolysis Energy Conserving stage, two glycolytic end-products or final products are made. Which of the following are the final glycolytic products?

During the first glycolytic step, 2 ATP molecules have to be invested. The energy from these ATPs is used to immediately make a new molecule so that it can be oxidized later on in glycolysis. What is the name of this new molecule?

The Kreb's cycle is a sequence of enzyme reactions that regenerate themselves once acetyl coenzyme A (CoA) is added. Citric acid is the first compound in this sequence of reactions. The cycle continues when citric acid is further oxidized yield a product in the final step of this cycle. What is the name of the final product in this cycle?

The Kreb's cycle completes two full turns for the oxidation of all pyruvic acid from glycolysis. How many total NADH molecules are made from Krebs cycle reactions only?

Which molecule would absolutely have to be present in order to keep the Krebs cycle turning and making more products?

During light-dependent photosynthesis, photosythetic microbes make NADPH. Ultimately, what will NADPH made in this step be used for?

The Calvin-Benson cycle is considered a cycle because the end product, ribulose bisphosphate (RuBP) in this sequence chemically reacts with CO2 to form more product, which in turn, can be used to start the process to make glucose. What is the name of the first compound made in this cycle?
