How can insulin deficiency lead to an increase in blood glucose concentration?
MakcuM [25]

When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.

Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis  ie increased gluconeogenesis .

With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.

Neville has low blood pressure and his pituitary started producing a homorone to maintain water balance his blood pressure event
ivanzaharov [21]

Answer: The options are missing in the question,the options are;

A) Positive feedback will stop the release of this hormone.

B) Positive feedback will speed up the release of this hormone.

C) Negative feedback will speed up the release of this hormone.

D) Negative feedback will stop the release of this hormone.

The correct answer to the question is option D

NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.

Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.

The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.

As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.

At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.
