The pancreas is a endocrine organ

That consists of exocrine and endocrine cells

Increases parasymp activity + this increases insulin release

Glucose cannot diffuse freely into adipose cells

The islets of Langerhans

Consist predominantly of beta cells

Diabetes Mellitus symptoms include

↑ plasma glucose , ↑ urine output, ↑ thirst

↑ facilitated diffusion of glu into liver cells via Glut 2

The mechanism of action of insulin is via

a tyrosine kinase receptor found in the cell membrane

Elevated insulin levels

Increases facilitated diffusion of glucose into adipo cells

increases glycogenolysis and increases gluconeogenesis

Type 1 Diabetes Mellitus is characterised by

sudden onset and sudden weight loss

Glucose affects insulin release by

closing K+ channels and opening Ca++ channels

Answers

1
The pancreas is a endocrine organ
Which secretes catecholamines
That produces urine
That consists predominantly of beta cells
That consists of exocrine and endocrine cells
2
Type 1 Diabetes Mellitus is
most common in adults
the most common form of diabetes
most common in children
only occurs in pregnant women
3
Eating a meal
Increases parasymp activity + this increases insulin release
Decreases parasymp activity + this decreases insulin release
Increases parasymp activity + this decreases insulin release
Increases parasymp activity + no effect on insulin
4
In the fasted state
Glucose cannot diffuse freely into adipose cells
There are no insulin receptors in adipose cells
GLUC is transported into adipose via non-INSU dependent mech
Glucose diffuses freely into adipose cells
5
Insulin is produced by alpha cells and is normally in high concentration in the fasted stated?
True
False
6
The islets of Langerhans
Consist predominantly of delta cells
Consist of alpha cells only
Consist predominantly of beta cells
Consist of alpha and beta cells only
7
Glucagon release is
Reduced by glucose
Not affected by glucose
Increased by glucose
OMG- this is freaking me out
8
Increased circulating glucose levels
decrease insulin release
I do not know
Increase insulin release
have no effect on insulin release
9
Diabetes Mellitus symptoms include
↓ plasma glucose, ↓ urine output, ↑ thirst
↑ plasma glucose , ↑ urine output, ↑ thirst
↓ plasma glucose, ↑ urine output, ↑ thirst
↓ plasma glucose, ↓ urine output, ↓ thirst
10
Increased circulating insulin levels
Increase glucose uptake
I do not know
Have no effect on glucose uptake
Decrease glucose uptake
11
Insulin
Helps to actively transport glucose into liver cells
↑ facilitated diffusion of glu into liver cells via Glut 2
stim insertion of Glut 4 transporter into liver cell memb
Increases glucose uptake into all cells in the body
12
The mechanism of action of insulin is via
A GPCR found in the cell membrane
a tyrosine kinase receptor found in the cytosol
An intracellular receptor
a tyrosine kinase receptor found in the cell membrane
13
Elevated insulin levels
Stimulates insertion of Glut 2 transporter into cell membran
Increases glucose uptake into all cells in the body
Increases facilitated diffusion of glucose into adipo cells
Helps glucose diffuse freely into adipose cells
14
Glucagon
reduces glycogenolysis and reduces gluconeogenesis
increases glycogenolysisand reduces gluconeogenesis
reduces glycogenolysis and increases gluconeogenesis
increases glycogenolysis and increases gluconeogenesis
15
Type 1 Diabetes Mellitus is characterised by
slow onset and sudden weight loss
slow onset and little weight loss
sudden onset and sudden weight loss
sudden onset but little weight loss
16
Glucose affects insulin release by
opening K+ channels
acting on a receptor
closing K+ channels and opening Ca++ channels
opening K+ channels and opening Ca++ channels
