Briefly describe the role that phosphofructokinase plays in cellular respiration. Describe the impact a lack of phosphofructokinase would have on cellular respiration and one sign and/or symptom that may be present in someone who suffers from this disorder

Oxidative decarboxylations—     involve loss of CO2 and the production of NADH.     do not occur in the TCA cycle.     involve loss of CO2 and the production of NAD.     occur three times in the TCA cycle.     involve loss of CO2 and the production of FADH2.

Answer the following questions:

Explain this table (shown in picture) from a study with the help of the information below and additional information from the article (shown in picture): Primary liver cancer is one of the most prevalent life- threating diseases in China, and liver resection is the major therapy for this malignancy. Recently, various methods have been advocated perioperatively to maintain liver function and promote liver regener- ation after liver resections. These include systemic interventions such as antibiotics in perioperative period and methods to improve general health and the immunity of the individual such as prebiotics and probiotics. Among them, nutritional support is also a vital approach to protect liver function. It has been demonstrated that a good preoperative nutri- tional status could reduce the postoperative morbidity or mortality and consequently the costs of care after surgery. Moreover, malnutrition is frequent in patients suffering from malignant liver disease. Optimization of…

Intermediary carriers are in a limited supply: When they cannot be recycled because of a metabolic block, serious consequences ensue. Think of some examples of these consequences.

Where is the first NADH molecule produced in cellular respiration?   options:   Conversion of pyruvate to acetyl coenzyme A   Conversion of acetyl coenzyme A to pyruvate   Reduction of oxygen to water   In the cytoplasm

Consider the last few minutes of a tough race, when the runner's energy reserves are depleted. Explain the advantage of converting pyruvate to lactate in muscle cells during intense anaerobic effort (i.e. in the absence of oxygen).

The co-enzyme that helps in the removal of carbon dioxide from pyruvate during the PDH mechanism is     Pyruvate oxidative decarboxylase     CoA     NAD+     Thiamine Pyrophosphate

Choose which enzyme is likely deficient based on the symptoms described below: Elevated blood lactate, alanine and pyruvate a) lactate dehydrogenase d) citrate synthase c) pyruvate dehydrogenase d) pyruvate kinase

Is it possible for someone poisoned with cyanide to benefit from artificial respiration or oxygenation (i.e., giving them oxygen)? Explain why or why
