What is the purpose of barium hydroxide Physioex?

Barium hydroxide is used for clearing proteins and cells so that clear glucose readings may be obtained.

Why does the color in the tubes vary Physioex?

Why does the color in the tubes vary? he appears to have impairment or borderline impairment of insulin-mediated glucose uptake by his cells. heparin is added to prevent blood clots. insulin-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise.

What is a glucose standard curve and why did you need to obtain one for this experiment did you correctly predict how you would measure the amount of plasma glucose?

What is a glucose standard curve, and why did you need to obtain one for this experiment? Glucose standard curve is a graphic tool to demonstrate the relationship between optical density and glucose concentration. You need it because you don’t have too many samples to compare with so you have to extrapolate.

What is the purpose of barium hydroxide quizlet?

barium hydroxide is added to prevent blood clots.

How does the pancreas regulate glucose in a healthy person?

When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them. This balance helps provide sufficient energy to the cells while preventing the nerve damage that can result from consistently high levels of blood sugar.

Why does the colors in the tubes vary?

the glucose standard curve. Stop & Think Questions: Why does the color in the tubes vary? The tubes contain different amounts of glucose.

Why were ovariectomized rats used in this experiment?

Ovariectomized rats were used in this experiment to ensure control over the hormones in the rats. Without the ovaries, the rats were not able to produce estrogen, and therefore had low baseline T scores already, since estrogen stimulates bone growth and protects against osteoprosis.

What are potential sources of variability when generating a glucose standard curve?

Activity Q 2.2: What are potential sources of variability when generating a glucose standard curve? Some potential sources include experimental error in measurement of the reagents and inherent variability of the spectrophotometer measurements.

What is the purpose of the glucose standard curve?

A glucose standard curve is a tool used to measure the FPG levels taken from several patients to diagnose the presence or absence of diabetes.

Why do we need glucose standard curve?

Standard curves represent the relationship between two quantities. They are used to determine the value of an unknown quantity (glucose concentration) from one that is more easily measured (NADH level).

How do you make a standard glucose curve?

The standard curve is created by measuring the responses of a known set of glucose standards, which are either provided by the manufacturer of the assay or can be easily generated through serial dilution of a glucose stock solution.

What is the condition that alloxan has caused in the experimental rat?

Alloxan-induced diabetes is a form of insulin-dependent diabetes mellitus that occurs as a result of alloxan administration or injection to animals [78], [79]. It has been successfully induced in a variety of animal species; rabbits, mice, rats, monkeys, cats and dogs [80], [81].

What was the effect of administering insulin to the diabetic rat?

In alloxan-diabetic rats insulin at high dosage markedly lowered incorporation of pyruvate-3J4C into blood glucose, but also stimulated its incorporation into liver glycogen. However, total incorporation into blood glucose and liver glycogen was decreased by insulin.

What is the purpose of potassium hydroxide in the aerobic respiration demonstration group of answer choices?

A small volume of potassium hydroxide solution (KOH) in the respirometer will remove the carbon dioxide as it is being generated during respiration. The KOH absorbs atmospheric CO2, producing a potassium carbonate precipitate.

Does epinephrine increase blood glucose?

Epinephrine causes a prompt increase in blood glucose concentration in the postabsorptive state. This effect is mediated by a transient increase in hepatic glucose production and an inhibition of glucose disposal by insulin-dependent tissues.

What controls the pancreas?

The pancreas is controlled by both the autonomic nervous system (ANS) and the endocrine system. The ANS has 2 divisions: the sympathetic and the parasympathetic. Nerves of the sympathetic division become active during stressful situations, emergencies, and exercise.

How does the pancreas detect blood glucose levels?

The beta cells of the pancreatic islets of Langerhans respond to changes in glucose concentration by varying the rate of insulin synthesis and secretion. Beta cells sense glucose concentration by the levels of the products of glucose catabolism.

What effect will the saline injections have on the control rats vertebral bone density?

The saline injections will not change the rat’s vertebral bone density (indicated by an unchanging T score).

How is blood sugar homeostasis maintained in non diabetics?

Discovery of Glucagon Thus maintaining adequate glucose levels in the blood are necessary for survival. On the other hand, inappropriate levels of glucose in the blood are a primary symptom of diabetes, a major degenerative disease in society. Normal glucose homeostasis is primarily maintained by glucagon and insulin.

What is gestational sugar?

Overview. Gestational diabetes is diabetes diagnosed for the first time during pregnancy (gestation). Like other types of diabetes, gestational diabetes affects how your cells use sugar (glucose). Gestational diabetes causes high blood sugar that can affect your pregnancy and your baby’s health.
