explain what caused the change in plasma ketone concentration over the course of the experiment

Explain what caused the change in plasma ketone concentration over the course of the experiment. The break down of fatty acids is what forms ketones so the intake of the meal that was filled with carbs is what caused the change in plasma ketone concentration over the course of the experiment.

Full Answer

What is plasma ketone and why does it matter?

Explain what caused the change in plasma ketone concentration over the course of the experiment. Since ketone levels are higher when glucose levels are lower, ketone concentration was higher when fasting and at 0hr post meal. Once glucose was introduced, ketone concentration dropped. THE EXPLANATION HAS BEEN GIVEN IN THE ATTACHED FILES. 4.

What kept the plasma glucose constant during the experiment?

Mar 25, 2022 · Laboratory Report 3. Explain what caused the change in plasma ketone concentration over the course of the experiment. The plasma ketone concentration is at its highest during the fasting stage where the body is using the lipid reserve. When you eat, the ketone amount drops and now the body can utilize newer resources.

How are ketone bodies metabolized in the brain?

Mar 31, 2016 · Explain what caused the change in plasma ketone concentration over the course of the experiment. Ketones changed from high during fasting to lower after eating and even after hour three because it first they were needed to generate ATP but droped because they were not needed as much for fuel. Explain how negative feedback caused the changes in plasma insulin …

How does insulin change the plasma glucose concentration over the course?

Explain what caused the change in plasma ketone concentration over the course of the experiment. The break down of fatty acids is what forms ketones so the intake of the meal that was filled with carbs is what caused the change in plasma ketone concentration over the course of the experiment.

What caused the change in plasma ketone concentration over the course of the experiment?

Explain what caused the change in plasma ketone concentration over the course of the experiment. The body was getting all the sugar it needed during 0 to 1 hour post meal and after that the levels started to go down. The body got what it needed and began to store the ketone's for later use.

How negative feedback caused the changes in plasma insulin concentration?

4. Explain how negative feedback caused the changes in plasma insulin concentration observed during the experiment. As insulin rises glucose falls, the decreased plasma glucose inhibits insulin release.

How does insulin change plasma glucose concentration?

As can be seen in the picture, insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range.

How does high blood ketone levels help the body conserve blood glucose?

Ketones are alternative fuels that are produced by the liver from fats when sugar is in short supply. Ketones are burned as fuel by muscle and other organs in the body, and the sugar is saved for the organs that need it.

What type of assay is used to measure plasma glucose and ketone levels?

The enzymatic analysis assay was used. The radioimmunoassay assay was used. As glucose is absorbed after the meal and blood plasma glucose increases, insulin secretion increases. Insulin and glucose levels peak 1 hr post meal.

What can high levels of ketones in the blood lead to?

High ketone levels may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death. A ketones in blood test can prompt you to get treatment before a medical emergency occurs.Nov 30, 2020

What are the factors causing increased blood glucose by glucagon?

When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

What is the effect of insulin?

Insulin is one of many hormones that helps the body turn the food we eat into energy. Also, insulin helps us store energy that we can use later. After we eat, insulin works by causing sugar (glucose) to go from the blood into our body's cells to make fat, sugar, and protein.Feb 1, 2022

Which hormone causes an increase in blood glucose quizlet?

The pancreas releases glucagon, which eventually causes blood glucose levels to increase.

What causes the liver to release glucose?

When nutrients become scarce, even after a few hours of fasting, the liver releases glucose to the blood by regulating the two primary glucose production metabolic pathways, glycogenolysis and gluconeogenesis. In order to achieve net glucose production or uptake, key enzymes in these pathways must be tightly regulated.

Does glucagon increase blood glucose levels?

Glucagon is a hormone that your pancreas makes to help regulate your blood glucose (sugar) levels. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels.Jan 3, 2022

Why does blood glucose levels fall?

In people with diabetes, the main causes of a low blood sugar level are: the effects of medicine – especially taking too much insulin, medicines called sulfonylureas (such as glibenclamide and gliclazide), medicines called glinides (such as repaglinide and nateglinide), or some antiviral medicines to treat hepatitis C.

How does insulin affect glucose levels?

The insulin changed the plasma glucose levels by raising dramatically from fasting to the one hour mark, but by hour 3 it droped again to almost the same levels as fasting. The glucagon remained almost the same on throughout the levels except that it lowered a bit 1 hour after the meal.

What is the function of glucagon in the liver?

Glucagon acts on liver cells to promote breakdown of glycogen into glucose and formation of glucose from lactic acid and certain amino acids. Turn in your highest-quality paper. Get a qualified writer to help you with. “ Blood Glucose Regulation ”. Get high-quality paper.

Why is diabetes mellitus dangerous?

Diabetic ketoacidosis is a dangerous complication of diabetes mellitus because the chemical balance of the body becomes too acidic.

What hormones are released during exercise?

1. During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.

What is the lowest insulin concentration during fasting?

Plasma insulin/glucagon concentration differed significantly. Insulin levels were at their lowest during the fasting time period at about 68 while glucagon was it its lowest during the 1 hour at 35.

How does insulin affect glucose levels?

Explain how insulin changed plasma glucose concentration over the course of the experiment. Insulin increases the transport of glucose into body cells causing blood glucose levels to decrease. When the insulin calmed down a bit and decreased that when a rise in glucose was presented.

What is Type 2 diabetes?

Type 2 diabetes is a chronic illness that is a result of the body's insulin not functioning correctly. It was formerly called adult-onset or insulin-dependent. It is also the most common kind of diabetes accounting for about 90 percent of all diabetes cases. Type 2 diabetes can also cause obesity and high cholesterol. About 6 percent of the population suffers from diabetes while about one-third of ...

What enzymes are involved in ketogenesis?

Ketogenesis requires the action of at least three enzymes: (I) mitochondrial Acetoacetyl-CoA thiolase, (II) mitochondrial 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthase (HMGCS2), and (III) HMG-CoA lyase, which form the ketone body, acetoacetate (Figure 1; hepatocyte). Open in a separate window. Figure 1.

How much energy does the brain use?

The human brain requires a significant amount of energy for normal brain function and accounts for about 20% of the body’s total energy expenditure at rest, despite the fact that the brain only represents ~2% of the total body weight [1].

Does keto diet increase ketone levels?

Besides fasting, ketogenic diets and nutritional ketogenic supplements can increase the circulatory pool of ketone bodies. The ketogenic diet mimics the metabolic profile of fasting, due to the high consumption of lipids and very low intake of carbohydrates, which is usually restricted to less than 30–50 g/day [23].

Does the brain use glucose?

Under normal physiological conditions the brain primarily utilizes glucose for ATP generation. However, in situations where glucose is sparse, e.g., during prolonged fasting, ketone bodies become an important energy source for the brain. The brain’s utilization of ketones seems to depend mainly on the concentration in the blood, ...
