Explain the process that is depicted by the diagram below. (What is the overall purpose of the process?What kind of organism uses this process? What is the overall significance of this process to life? *please answer the question being asked. answer should be short and concise
Deficiencies in the conversion of Pyruvate to Acetyl CoA may result in severe neurological developmental defects in children. A child presents with these symptoms. Tests reveal that this child has abnormally high levels of Pyruvate in mitochondria and low levels of Hydroxyethyl TPP. What is your diagnosis on the specific enzyme deficiency in this child that may be causing the symptoms Explain in 3 – 5 sentences
Pyruvate + NAD+ + CoA → Acetyl COA NAIDHI + H + CO₂ This is the overall reaction for the pathway of Glycolysis Oxidative decarboxylation of pyruvate Fatty acid oxidation Ellectron transport Oxidative phosphorylation TCA or citric acid cycle
All the reactions involved during gluconeogenesis occur in the cytosol except the one catalyzed by phosphoenolpyruvate carboxykinase. Group of answer choices True False
Identify a pathway for utilization of the four carbons of acetoacetate in cholesterol biosynthesis. Carry your pathway as far as the rate-determining reaction in cholesterol biosynthesis. Drag the appropriate labels to their respective targets. succinyl-CoA succinate acetyl-CoA CoA-SH acetoacetyl-CoA HMG-CoA 2NADP 2NADPH+ 2H acetoacetate K UHL return to a mevalonate + CoA-SH
Fatty acid degradation stimulates the citric acid cycle through the activation of pyruvate carboxylase by acetyl-CoA. Why would the activation of pyruvate carboxylase increase energy generation from fatty acids?
Fill in the gaps (type your answers in all capital letters): Lactate fermentation is an important pathway, allowing the body to regenerate the co-factor in the absence of (molecule). During the process of cellular respiration, the enzyme converts pyruvate to acetyl-coA using five co-factors, including |(name one). Acetyl-CoA is a substrate of the ТСА сycle, where tior one acetyl-CoA one of the TCA cycle produces molecules of and 1 molecule of that function as electron carriers.
Although glucose cannot be formed from acetyl-CoA, triglycerides can enter the glycolytic pathway via which process? O Acetyl-CoA → oxaloacetate → phosphoenolpyruvate O Palmitoyl-CoAB- ketoacyl-CoA → a-ketoglutarate O Glycerol → DHAP Acyl-CoA glucose
Below is an image showing how cellular respiration is regulated. Imagine someone ingested a toxin that prevents pyruvate from entering the mitochondria. Which of the following statements is true? Inhibits ATP Glucose GLYCOLYSIS Copyright 2018 Pearson Canada Inc. Fructose 6-phosphate Phosphofructokinase Fructose 1,6-bisphosphate Pyruvate Acetyl COA CITRIC ACID CYCLE Oxidative phosphorylation AMP I Stimulates Inhibits Citrate The amount of citrate in the cell would decrease, leading to a decrease in the activity of phosphofructokinse. The amount of citrate in the cell would increase, leading to a decrease in the activity of phosphofructokinse. The amount of citrate in the cell would decrease, leading to an increase in the activity of phosphofructokinse. The amount of citrate in the cell would increase, leading to an increase in the activity of phosphofructokinse.
Please explain and give the correct answer
Under aerobic conditions of high ratios of NADH/NAD+ and ATP/ADP, as pyruvate is utilized for its carbon skeleton, which molecules would you expect to see significant radiolabeling in the liver? Select all that apply. **Please note some molecules contain more details, including not only molecule name, but location of the label. Pick the options that are accurate for the above situation. O Glucose C-2 and C-5 O Glucose C-1 and C-6 O Glucose C-2 only Pyruvate C-1 Lactate C-2 for export O CO2 from TCA cycle shows some radiolabel Label is halved over many TCA cycles Oxaloacetate O Malate
