Imagine an individual is suffering from low blood glucose levels and glucose can be clinically administered. If we can intravenously supply glucose-6-phosphate to muscle cells instead of glucose, knowing that there is a cost associated with converting glucose to glucose-6-phosphate (1 ATP spend), would it be best to administer glucose-6-phosphate directly, instead of glucose to a patient in need? Would this be effective? Explain why or why not. Note: this patient is suffering from general (i.e. total body) low blood glucose levels.
Yes glucose 6 phosphate can be given instead of glucose when the patient suffers low blood glucose. Glucose becomes glucose 6 phosphate and enters into glycogen or other metabolism and the conversion requires utilisation of ATP molecule and providing direct glucose 6 phosphate.
Glucose 6 phosphate isis high energy compound releases more free energy in metabolism than plain glucose . Hence glucose 6 phosphate can be utilised for intraveous administration

A patient comes into clinic suffering from lack of energy and very low hemoglobin levels. You run some tests and determine his red blood cells have a high level of phosphoenolpyruvate with little pyruvate produced and decreased ATP levels. You quickly deduce that he has a mutation in which glycolytic enzyme(s)?
QUESTION 9 In skeletal muscle under anaerobic conditions, pyruvate is further reduced to lactate. What is the net equation for the payoff phase of glycolysis? glyceraldehyde-3-phosphate + 2 ATP + Pi ---> lactone + NAD+ glucose+2ATP - 2Glyceraldehyde-3-Phosphate + 2ADP + 2H+ 2glyceraldehyde-3-phosphate + 4ADP + 2Pi >2Lactate + 4ATP None of the above QUESTION 14 What is the ratio of carbon-bound hydrogens to carbon of glucose? 6/6 776 12/6 6/7 QUESTION 29 Why would it be advantageous to plants...
26. Why did Jessie’s carnitine deficiency cause her to have abnormally low plasma glucose levels at the end of a fasting study, when compared to a healthy person who has fasted for the same length of time? In the absence of carnitine, the liver stores large amounts of glycogen; absorption of glucose to create these stores depletes blood glucose Carnitine acts as a hormone and stimulates glucose release from the liver; lack of carnitine results in loss of hepatic glucose...
1. A patient presents in your surgery with an inability to maintain blood sugar levels in long periods (20 hours) between meals. Tests show that glucose is converted to lactate normally in liver in the well-fed state, and that pyruvate carboxylase and phosphoenolpyruvate carboxykinase have normal activities in liver in periods between meals. Your colleague reminds you that glucagon stimulates glycogen degradation, so you administer glucagon to the patient (who was well fed prior to the test) and find that...
Quiz 10 1. (2 points) Which of the following conditions would lead to the highest levels of lac operon expression? a) High lactose, high glucose b) High lactose, low glucose c) Low lactose, high glucose d) Low lactose, low glucose e) None of the above would have any lac operon expression 2. (2 points) Which of the following is true concerning molecular genetics? a) tRNA carries amino acids into the nucleus in eukaryotic cells b) DNA polymerase moves towards the...
1. What is happening in a healthy individual about an hour into a glucose tolerance test? (Note: At this early time-point, blood glucose levels are still high. Also, remember that a person who is taking a glucose tolerance test was fasting for 12 hours prior to the test!) (Select ALL that apply!) Hint: Review pages 319-325, 462-467 and 489-491 of Tymoczko 3E before attempting this question. A. Glucose is being exported by the liver B. Glucose is being taken up...
The patient was a 2 year old boy who presented with fasting hypoglycemia and acidosis. The liver was enlarged three-fold and kidneys two-fold. Hypoglycemia responded to oral doses of glucose but not to administered glucagon or epinephrine. During hypoglycemic episodes, lactic acid in the blood increased almost 10-fold higher than normal. Unlike the response in normal individuals, administration of oral galactose did not increase blood glucose concentrations but blood lactate levels were increased. Urine contained high levels of lactate. A...
