Q

Is the movement of sodium and amino acids from the intracellular fluid, across the cell wall, into the blood, energetically a free process?

A

No. Although the amino acids do not require energy as they are moving from a high to low concentration the sodium potassium pump is required to move the sodium and this does require energy.

Q

Define emulsification.

A

Bile salts in the duodenum break large fat globules into smaller fat droplets, increasing the surface area available to lipase enzymes. The non-charged side of bile salts will coat the smaller globules of fat so they can’t stick back together. Lipase then attacks.

Q

List the functions of the kidney.

A
  • Regulating the total volume of water in the body and the total concentration of solutes in that water (osmolality).

  • Ensuring long-term acid-base balance.
  • Excreting metabolic wastes and foreign substances such as drugs or toxins.
  • Producing erythropoietin and renin, important molecules for regulating red blood cell production and blood pressure, respectively.
  • Converting vitamin D to its active form.
  • Carrying out gluconeogenesis during prolonged fasting .

Q

Describe the process of filtration.

A
  • It is basically a passive process where substances are moved across the pressure gradient, so they are going from high pressure to low pressure
  • The high pressure is caused by the blood pressure and the surrounding glomerular capsule is a fairly low pressure
  • Most substances are able to be filtered and this includes things that we would like to keep, including glucose, amino acids, sodium, water
  • But substances that shouldn’t be filtered are large substances such as proteins and then your red and your white blood cells
  • Once you have formed the filtrate and it has entered the glomerular capsule, then the urine is going to travel through the rest of the nephron

Q

What is the path of absorption for fats?

A

94
Q

If you want to reabsorb calcium in the DCT, what hormone do you need?

97
Q

What hormone is required to secrete potassium in the DCT?

A

aldosterone

98
Q

Why doesn’t the concentration gradient get all mixed up in the Loop of Henle?

A

Because of the vasa recta that surrounds it. It is a blood vessel that also has a counter current mechanism and this helps to preserve the concentration gradient.

99
Q

Why is the concentration gradient in the collecting duct so important?

A

So we can absorb as much or as little water as we need in the collecting duct.

100
Q

What 2 things can happen to make the blood in the vasa recta the same as the interstitial fluid as the concentration in the interstitial fluid changes?

A

1) Could move sodium and chloride ions into the blood
2) move water out

(this reflects near the descending limb; opposite near the ascending limb)

101
Q

What two proteins does aldosterone enable to be created?

A

sodium channel proteins and sodium-potassium pumps

102
Q

What process is required to create aldosterone (briefly)

A

renin-angiotensin- aldosterone complex

103
Q

Why is calcium reabsorption so important?

A
  • Needed for skeletal and cardiac muscle contraction
  • Needed for the secretion of hormones and enzymes
  • Needed for action potentials in the heart
  • Needed for releasing neurotransmitters
104
Q

What is arguably the most important ion?

A

potassium. Should have this in high concentration in your cells.

105
Q

What is one of the most important functions in the DCT?

A

Secreting potassium ions.

106
Q

What hormone controls the secretion of potassium in the DCT?

A

aldosterone

107
Q

True or false, High concentrations of potassium in the blood will directly trigger the adrenal glands to produce aldosterone. The renin-angiotensin-aldosterone complex is not required.

A

True

108
Q

What is the typical concentration of urine at the DCT and the collecting duct?

A

300

109
Q

In the collecting duct, which substances will be reabsorbed if needed?

A
  • sodium (requires aldosterone)

- water; one of the most important places (required ADH)

110
Q

Where does most sodium reabsorption happen?

A

DCT and collecting duct (both require hormone aldosterone)

111
Q

What hormone is required to reabsorb water in the collecting duct?

A

ADH

112
Q

The collecting duct is impermeable to water unless you have which hormone? What does the hormone do?

A

ADH. ADH sticks aquaporins in the membrane of the collecting duct.

113
Q

Even if you have aquaporins in your membrane due to the ADH, what else do you need to have in place to move water?

A

concentration gradient in the interstitial fluid

114
Q

Why do we need ADH in the collecting duct and not the PCT?

A
  • due to membrane structure
  • the PCT always has aquaporins
  • collecting duct needs ADH to create aquaporins
115
Q

If you have too much sodium in the interstitial fluid at the DCT or the collecting duct, what do you need?

A

ANP; it will enable you to secrete sodium

116
Q

True or false. You can secrete potassium at the collecting duct.

A

True

117
Q

Are lungs or kidneys faster at regulating acid-base balance?

A

lungs (can only deal with metabolic acid base problems)

118
Q

What kinds of acid-base problems do the kidneys help with?

A

Both metabolic and respiratory

119
Q

In respiratory acidosis, which way is the equation being driven?

A

CO2 + H2O —-> H2CO3 ——> HCO3- + H+

Causing me to produce too many hydrogen ions

120
Q

How many more bicarb ions are there in mammals than hydrogen ions?

A

600,000 times more

121
Q

Why might you have respiratory acidosis?

A
  • not able to breathe off CO2 like we should
  • pneumonia, severe bronchitis, emphysema (anything that will trap CO2 in the lungs)
  • lungs are malfunctioning
122
Q

What can the kidney do to help with respiratory acidosis?

PCT and collecting duct (reabsorb bicarb)

A

1) reabsorb more hydrogen in collecting duct

2) secrete more bicarb in collecting ducts

Q

What are the functions of the liver?

A

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

The primary functions of the liver are:
Bile production and excretion.
Excretion of bilirubin, cholesterol, hormones, and drugs.
Metabolism of fats, proteins, and carbohydrates.
Enzyme activation.
Storage of glycogen, vitamins, and minerals.
Synthesis of plasma proteins, such as albumin, and clotting factors.

Q

List the enzymes and other main substances secreted by the pancreas.

A
  • trypsinogen
  • chymotrypsinogen
  • procarboxypeptidase
  • lipase
  • amylase
  • bicarb
  • ribonuclease
  • deoxyribonuclease
129
Q

What does lipase do to triglycerides?

A

Chops off two fatty acids which leaves two free fatty acids and a monoglyceride (glycerol + fatty acid)

130
Q

Is the process for absorbing glucose and galactose considered active or passive?

A

Active. B/c you need ATP to get sodium out of the cell that was used for co-transport.

131
Q

Is the process for absorbing fructose considered active or passive?

A

Passive. Does not use co-transport; can get in and out using facilitated diffusion.

132
Q

Is the process for absorbing amino acids considered active or passive?

A

Active. Use co-transport and need ATP to get the sodium out of the cell.

133
Q

Is the process for absorbing the individual elements of a nucleotide (phosphate, sugar, base) considered active or passive?

A

Active. In via active processes, out via diffusion.

134
Q

List in correct order the enzymes required for protein breakdown.

A
  • pepsin (stomach)
  • membrane bound enteropeptidase
  • trypsinogen - converted to trypsin (by the enteropeptidase)
  • chymotrypsinogen –> converted to chymotrypsin
  • procarboxypeptidase –> converted to carboxypeptidase
  • aminopeptidase
135
Q

True or false. Bicarb is reabsorbed in the PCT.

A

True
