What is the primary function of insulin, which is synthesized in the beta cells of the pancreas?
To be secreted in response to low blood glucose levels
To increase the uptake of glucose by muscle and fat cells.
To increase the breakdown of glycogen into glucose in the liver.
. To promote the formation of glucose from non-carbohydrate sources.
Which of the following describes the process of gluconeogenesis?
The formation of glucose from precursors like amino acids and glycerol.
The breakdown of glycogen to release glucose into the bloodstream.
The conversion of glucose into glycogen for storage in the liver and muscles.
The non-enzymatic attachment of glucose to proteins like haemoglobin.
According to the diagnostic criteria provided, a fasting blood glucose (FBG) result of 6.4 mmol/L would be classified as what?
Hypoglycaemia
Impaired fasting glycaemia
Normal
Diabetes Mellitus
What is the primary advantage of using the Glycated Haemoglobin (HbA1c) test for monitoring diabetes?
It is the simplest form of monitoring and can be done without a blood sample.
It can definitively diagnose early (reversible) diabetic nephropathy.
It provides an immediate, real-time measurement of blood glucose.
Diabetes MellitusIt reflects the mean blood glucose level over the previous 2 months.
Which carbohydrate is a polysaccharide used for glucose storage in plants and is found in foods like grains, pasta, and bread?
Cellulose
Glycogen
Starch
Fructose
During an Oral Glucose Tolerance Test (OGTT), which of the following patient preparations is required?
The patient drinks a 75 g glucose load and has a single blood sample taken 30 minutes later.
The patient should follow a low-carbohydrate diet for 3 days prior to the test.
The patient must avoid drinking any water during the test.
The patient must fast overnight and remain inactive during the test.
Which hormone is secreted by the alpha cells of the pancreatic islets in response to hypoglycaemia?
Growth Hormone
Glucagon
Adrenaline
Insulin
Why is sucrose considered a non-reducing sugar?
It is a polysaccharide with too many bonds.
It cannot be broken down into monosaccharides.
It contains a fructose molecule, which cannot act as a reducing agent.
Its linkage involves the aldehyde and ketone groups of both monosaccharides.
Which condition is characterized by an albumin excretion rate between 30 mg/day and 300 mg/day and is used as a marker for early diabetic nephropathy?
Microalbuminuria
Hypoglycaemia
Ketoacidosis
Glycosuria
