Starch and glycogen are both


What are some reducing carbohydrates?

Glucose,maltose, fructose, lactose, galactose

Name a nonreducing carbohydrate.


The nervous system can't store or concentrate glucose so it depends on glucose from the _______.


Glucose is stored as:


Glucose is converted to glucose-6-phosphate in a process catalyzed by the enzyme:


Glucose-6-phosphate is broken down to pyruvic acid in which pathway?


Glucose-6-phosphate is converted to glucose-1-phosphate, then glycogen in which pathway?

Hexose monophosphate

What is the name of the process by which glucose is converted to pyruvate or lactate?


What is the name of the process by which glycogen is converted back to glucose-6-phosphate?


What is the primary hormone responsible for entry of glucose into cells?


Insulin is synthesized by:

Beta cells of the islets ofLangerhans in pancreas

Insulin is released when glucose is:


What is the primary hormoneresponsible for increasing glucose level?


Glucagon is synthesized by:

alpha cells of the isletsof Langerhans in the pancreas

Which hormones decrease glucose levels?


Which hormones increase glucose levels?

glucagon, epinephrine,glucocorticoids, growth hormone, ACTH, thyroxine

What are the lab findings in hyperglycemia?

Increasedglucose in plasma and urine, increase urine specific gravity, increase serumand urine osmolality, ketones in serum and urine, decreased blood and urine pH,electrolyte imbalance

A group of metabolic diseasescharacterized by hyperglycemia resulting from defects in insulin secretion,insulin action, or both are known as:

diabetes mellitus

Type I DM is caused by:

destruction of Beta cells,resulting in an absolute deficiency of insulin; genetic

Ketoacidosis is seen in:

Type I DM

Ketones are formed from:

the oxidation of fatty acids

Type II diabetes is caused by:

dysfunctional insulinreceptors leading to a relative insulin deficiency

In ______________________, fetal insulin secretion isstimulated in the neonate of a mother with diabetes; when the infant is bornand umbilical cord is cut, the infant’s oversupply of glucose is abruptlyterminated, causing severe hypoglycemia

gestational diabetes

Criteria for testing for pre-diabetes/diabetes includes:

,Familyhistory, Race/ethnicity(African American, Latino, Native American), Signsof insulin resistance (acanthosis nigricans, hypertension, dyslipidemia, PCOS), Maternalhistory

GlycosylatedHemoglobin/Hemoglobin A1c

CSF glucose should be about __________% of the blood glucose level


If the CSF glucose is decreased and protein increased, the patient likely has:

bacterial meningitis
