labs 11 & 12

Question 1

what would CHO be broken down in to for the body to absorb

Answer 1

monosaccrides
or disaccharides

Question 2

what whould protein be broken down into for absorbtion into the blood

Answer 2

peptides - then to amino acids

Question 3

what would fats break down into for absorbtion

Answer 3

monoglycerides
fatty free acids
glycerols

Question 4

why can’t amino and peptide cross phosphlipid by layer

Answer 4

becuase they aren’t lipid souluble must have transporter

Question 5

why don’t micelles need a channel

Answer 5

because they are fat soluble

Question 6

why to you need to coat lipids with bile salts

Answer 6

to keep them seperate so enzyme lipase can break down triglycerides into substances

Question 7

what escape through the basolateral membrane with lipids

Answer 7

chylomicron

Question 7

what escape through the basolateral membrane with lipids

Answer 7

chylomicron

Question 8

what is the normal range for blood pH

Answer 8

7.35 -7.45

Question 9

what is the typical range for urine pH

Answer 9

4.5 -8

Question 10

why are the normal pH ranges so different for blood and urine

Answer 10

Blood pH must be kept within a small range where proteins work best.
Urine must change as it carries more or less acid, in order to keep the blood pH constant

Question 11

what is acidic urine associate with what type of diet

Answer 11

high in meat sugar and alcohol

Question 12

alkalin urine is associated with what type of diet

Answer 12

high in vegetables, low sugar

Question 13

with exercise do we expect peripheral to increase

Answer 13

yes - blood vessesl diluate more at your skin - because of heat loss doesnt have happen quickly

Question 14

is core or peripheral more stable

Answer 14

core

Question 15

if room is warm would peripheal temp increase

Answer 15

yes - if you don’t sweat as much

Question 16

if room is cool would peripheal temp increase

Answer 16

likely to decrease if you sweat a lot or room cold
- getting rid of heat quickly

Question 17

why does the body try to maintain constant core temp

Answer 17

protein need optimal temp to work properly - work best in small range

Question 18

if too hot wat happens to protein

Answer 18

denature

Question 19

if too cold what happens to protein

Answer 19

don’t work properly - move more slowly

Question 20

if temp receptors change what receptrs detect this

Answer 20

thermoreceptors

Question 21

what part of the brain control breathing rate

Answer 21

neurons in brain stem

Question 22

what is oxygen consumption

Answer 22

amount of oxygen all your cells use per minute
- oxygen taking in when inhaling

Question 23

more fit you are what does this mean for VO2

Answer 23

the higher it will be

Question 24

if you exercise will this also increase VO2 and why

Answer 24

yes - skeletal muscels cells produce more carbon dioxide as they make more ATP

Question 25

where is the dead space air and alveolar air capture in tube

Answer 25

deadspace is blown into the far end of the tube, alveolar air sits in the tube closest to mouth

Question 26

what air was sampled from tube w/ syringe

Answer 26

alveolar air

Question 27

what does hyperventilation causes CO2 to do

Answer 27

levels to drop
