Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of
katrin2010 [14]

Answer:

Liver phosphorylase a concentration decreases when glucose enters the blood.

The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form

As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form

Explanation:

Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase <em>a</em> is converted (and inactivated) into the <em>b</em> form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase <em>a</em>, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase <em>a</em>.

Glands such as the thyroid, that secrete their products directly into the blood rather than through ducts are classified as_____
kondaur [170]

Answer:

Such glands are classified as endocrine glands.

Explanation:

Endocrine glands also known as ductless glands produce and secretes hormones (chemical substances) directly into the bloodstream to regulate the activities of cells or organs. The endocrine glands make-up the endocrine system. This system influence reproduction, metabolism, growth and many other body functions. The endocrine glands include the hypothalamus, the pituitary, thyroid, ovaries, testes, pineal gland, parathyroids, pancreas and adrenal glands.

In contrast to the endocrine glands is the exocrine glands. The exocrine glands produce and secretes their hormones through ductal system onto epithelial surface. Example of exocrine glands are sebaceous glands of the skin, the pyloric and Cardia glands of the stomach, salivary glands etc.
