What is the product of glycolysis in the Krebs cycle?
A. Pyruvic acid, the product of glycolysis, is the starting block for both the Krebs cycle and fermentation. B. Glucose is split in glycolysis and produces large amounts of ATP. C. The electron transport chain is the final step for both fermentation and aerobic respiration.
What is the role of ATP in the break down of glucose?
B. ATP makes it easier to break apart glucose into two three-carbon molecules. C. ATP is used to reduce NAD+ to NADH. D. ATP is used to convert DHAP into G3P.
How many ATP are produced from glucose during glycolysis?
This process yields two ATP with every cycle. Glucose is phosphorylated when it is passed onto the glycogenesis reactions. Glucose is phosphorylated when it is passed onto the glycogenesis reactions. Glycolysis takes place in the________________.
What is the most specific glucose method?
The hexokinase/glucose-6-phosphate dehydrogenase (G6PD) method developed by the American Association for Clinical Chemistry has been accepted as the reference method for glucose determination.
What is the main source of manufacturing glucose?
Glucose is manufactured by plants with the aid of energy from the sun in the process called photosynthesis. This synthesis is carried out in the small energy factories called chloroplasts in plant leaves.
What are the productions which helps to increase in blood glucose level?
The main hormones of the pancreas that affect blood glucose include insulin, glucagon, somatostatin, and amylin. Insulin (formed in pancreatic beta cells) lowers BG levels, whereas glucagon (from pancreatic alpha cells) elevates BG levels.
Why is glucose high after surgery?
Surgery and anesthesia cause the release of stress hormones. These hormones make the body less sensitive to insulin which may result in elevated blood sugars.
What are some sources of a lot of glucose?
Foods naturally high in pure glucose include honey, agave, molasses, dried fruit, fruits, fruit juices, and sweet corn. These foods are healthy, in moderation, as part of a balanced diet, especially fresh fruits. Foods that typically have a lot of added glucose include sauces, salad dressings, pies, and sugary drinks.
What are the 3 sources of glucose?
The sources are: 1. From Carbohydrates of the Diet 2. From Various Glucogenic Compounds 3. From Liver Glycogen by Glycogenolysis.
Which mechanism is most likely to be responsible if when your blood sugar level rises the level of sugar goes back down to a set point?
When blood sugar levels rise above the set point, the hormone insulin signals the liver to absorb the excess sugar. When blood sugar levels drop below the set point, the hormone glucagon signals the liver to release its stored glucose to the bloodstream.
Does insulin increase blood glucose?
Insulin is a hormone your pancreas makes to lower blood glucose, or sugar.
Does insulin increase blood glucose levels?
Insulin helps blood sugar enter the body's cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too.
Does anesthesia increase glycogen stores?
Brain glycogen levels have also been proposed to increase during general anesthesia, and the degree of increase is related to both the depth and duration of general anesthesia and the type of anesthetic used [24–26].
Does surgery affect glucose levels?
Surgical patients commonly develop hyperglycemia related to the hypermetabolic stress response, which increases glucose production and causes insulin resistance. Although hyperglycemia is associated with worse outcomes, the treatment of hyperglycemia with insulin infusions has not provided consistent benefits.
Does anesthesia cause low blood sugar?
The results showed a significant reduction in the blood sugar of the patients undergoing spinal anesthesia within 1–6 h after the operation in comparison with the patients undergoing general anesthesia. The blood sugar of the patients was not measured during the operation.
