Exam 7: Microbial Metabolism

The redox carriers of the electron transport chain that have a tightly bound metal atom responsible for accepting and donating electrons are

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. A 67-year-old patient with severe sepsis undergoes a full infectious workup upon admittance to the intensive care unit. Cultures of urine, blood, sputum, and cerebral spinal fluid are obtained. The cultures do not yield a specific organism, so further analysis of the sample is done to determine the characteristics of the microorganism. The metabolic processes are analyzed in the lab. -What is the maximum net yield of ATP from anaerobic respiration?

ATP synthase is a complex enzyme needed for oxidative phosphorylation.

A holoenzyme is a combination of a protein and one or more substances called

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. A patient with severe anorexia nervosa is admitted to the hospital for medical treatment. The patient presents with severe malnutrition and evidence of organ dysfunction. Labs are drawn and maintenance IV fluids are initiated. -As the RN,you initiate IV fluid therapy for the patient.Knowing the importance of cellular energy production,which of the following maintenance IV fluids would you expect to be ordered by the physician?

Enzymes that are only produced when substrate is present are termed

All of the chemical reactions of the cell are called

Formation of peptide bonds between amino acids to build a polypeptide would be called

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. A 67-year-old patient with severe sepsis undergoes a full infectious workup upon admittance to the intensive care unit. Cultures of urine, blood, sputum, and cerebral spinal fluid are obtained. The cultures do not yield a specific organism, so further analysis of the sample is done to determine the characteristics of the microorganism. The metabolic processes are analyzed in the lab. -Biochemical testing reveals that the organism further reduces nitrite to produce nitrous oxide.Based upon this by-product,which of the following is the most likely catabolic pathway utilized by this organism?

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

Fatty acids can be converted to acetyl-CoA for entering the Krebs cycle by the process of

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

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. A newborn infant screening yields a positive result for biotinidase deficiency. As the RN, you provide education for the patient’s parents regarding the role of enzymes in metabolism and this enzyme deficiency disorder. -Inborn errors of metabolism

A patient with severe anorexia nervosa is admitted to the hospital for medical treatment. The patient presents with severe malnutrition and evidence of organ dysfunction. Labs are drawn and maintenance IV fluids are initiated. -You instruct the patient that although bacterial cells can also undergo aerobic respiration,

A 67-year-old patient with severe sepsis undergoes a full infectious workup upon admittance to the intensive care unit. Cultures of urine, blood, sputum, and cerebral spinal fluid are obtained. The cultures do not yield a specific organism, so further analysis of the sample is done to determine the characteristics of the microorganism. The metabolic processes are analyzed in the lab. -The organism is found to grow throughout the entire tube of broth media.Which of the following terms best describes the oxygen requirement of this organism?

Feedback inhibition,a negative feedback mechanism that regulates enzymes,is best described as

During aerobic cellular respiration,the final electron acceptor is

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.

When enzyme action stops due to a buildup of end product,this control is called

Reduction of nitrogen-oxygen ions,such as nitrate,by some bacteria is called
