By which process would insulin be secreted from beta islet cells of the pancreas?
a. Active transport
b. Exocytosis
c. Diffusion directly through the cell membrane
d. Facilitated diffusion through a channel in the cell membrane
Through which cell membrane structures does glucose move, as it enters absorptive cells lining the GI tract?
a. Phospholipids
b. Na+ co-transporters
c. Aquaporins
d. Vesicles
In what form is excess glucose stored in the body?
a. Protein and glycogen
b. Protein and fat
c. Fat and glycogen
d. Only fat
In which tissues and/or organs is glucose stored?
a. Adipose (fat) and skeletal muscle
b. Adipose (fat) and liver
c. Skeletal muscle and liver
d. Skeletal muscle, liver and adipose (fat)
What role does skeletal muscle have in blood glucose homeostasis, after a meal (blood glucose is high)?
It stores glucose, as glycogen
It stores glucose, as fat
It breaks down glycogen into glucose
It releases insulin in exchange for glucose
Too much glucose in the blood can cause nerve damage. What disease is associated with high blood glucose and nerve damage?
a. Diabetes
b. Asthma
c. Bulimia
d. COVID19
What role does the Cephalic Phase of Insulin Release (CPIR) play in blood glucose homeostasis?
a. Positive feedback amplification
b. Negative feedback control
c. Feedforward control
d. All of the above
Activation of which division of the nervous system will cause blood glucose concentration to be increased, to help the body deal with stress?
a. Somatic nervous system
b. Sympathetic nervous system
c. Parasympathetic nervous system
d. Enteric nervous system
Which division of the nervous system, comprised of neurons within the walls of the gut, is most active during a meal?
a. Somatic nervous system
b. Sympathetic nervous system
c. Parasympathetic nervous system
d. Enteric nervous system
Which division of the nervous system stimulates increased activity in the enteric nervous system during a meal?
a. Somatic nervous system
b. Sympathetic nervous system
c. Parasympathetic nervous system
d. Enteric nervous system
Why do blood vessels of the GI tract (gut) vasodilate during a meal?
To decrease blood supply to working skeletal muscles
To decrease blood supply to working smooth muscle in the GI tract
To increase blood supply for digestion and absorption in the GI tract
To increase blood supply to working skeletal muscles
During a stress response how would the cardiovascular system help with delivery of glucose to working cells?
Decreased heart rate = decreased blood pumped out of the heart
Vasoconstriction of blood vessels that supply working tissues
Increased total peripheral resistance (TPR) = decreased blood pressure
Increased cardiac output (L/min) = increased blood to working cells
Cells use glucose to make ATP. Which respiratory gas do cells also require, in the process of making ATP?
a. Oxygen
b. Carbon monoxide
c. Carbon dioxide
d. Helium
Which respiratory gas do cells produce, in the process of making ATP?
a. Oxygen
b. Carbon monoxide
c. Carbon dioxide
d. Helium
How can the respiratory system assist cells with increased ATP production and use during exercise?
a. Increase barometric pressure
b. Increase ventilation
c. Increase cardiac output
d. Increase mean arterial blood pressure (MABP)
Excess glucose can be stored as fat. As fat cells get bigger they make and release more inflammatory chemicals. What are these inflammatory chemicals called?
a. Acetylcholines
b. Neutrophils
c. Albumin
d. Cytokines
Which inflammatory disease makes it difficult for the body cells to use glucose?
a. Fatty liver disease
b. Diabetes
c. Heart disease
d. High blood pressure
How and why is blood glucose concentration changed by adrenaline (epinephrine)?
Adrenaline decreases blood glucose, because cells don't use as much during periods of relaxation
Adrenaline decreases blood glucose, because cells use fat as fuel during periods of stress
Adrenaline increases blood glucose, because cells use more during periods of relaxation
Adrenaline increases blood glucose, because cells use more during periods of stress
How and why is blood glucose concentration changed by cortisol?
Cortisol decreases blood glucose, because cells use less during periods of relaxation
Cortisol decreases blood glucose, because cells use less during periods of stress
Cortisol increases blood glucose, because cells use more during periods of relaxation
Cortisol increases blood glucose, because cells use more during periods of stress
How and why is blood glucose concentration changed by growth hormone (GH)?
Growth hormone decreases blood glucose, as cells use less during periods of sleep and growth (e.g. puberty)
Growth hormone decreases blood glucose, by stimulating storage in the liver during sleep and growth (e.g. puberty)
Growth hormone increases blood glucose, for cells to use during periods of sleep and growth (e.g. puberty)
Growth hormone has no effect on blood glucose
Testosterone enhances the effect of a pancreatic hormone, that triggers cells to take and use glucose from the blood. What is that pancreatic hormone?
a. Adrenaline
b. Growth hormone
c. Glucagon
d. Insulin
Testosterone helps cells take glucose out of the blood. Because of this effect, testosterone can be used to help manage symptoms of which of the following conditions?
a. Low blood pressure
b. Type 2 diabetes
c. Dehydration
d. Both b and c
Which of the following hormones is important because it increases blood glucose levels during childhood and puberty?
a. Growth hormone
b. Insulin
c. Oxytocin
d. Anti-diuretic hormone (ADH)
When products of ___________ digestion are absorbed, blood glucose ___________.
a. Protein; increases
b. Fat; decreases
