quiz 5 carbs continued

Question 1

how long does the insulin effect last

Answer 1

3-4 hours

Question 2

intensity of insulin effect

Answer 2

amount of insulin = the effect
high insulin = greater intensity of effect
low insulin = decrease intensity

Question 3

hyperinsulinemia

Answer 3

stores fat well and doesnt burn fat well
(inhibits lipolysis)

Question 4

reactive hypoglycemia

Answer 4

really low blood sugar
-leads to nausea, fatigue, dizzy

Question 5

higher quality CHO food, greater fiber content leads to

Answer 5

less affect on fat storage

Question 6

low quality CHO food (sugar and starches) leads to

Answer 6

store a lot of fat and little burning

Question 7

insulin impacts fat metabolism by

Answer 7

stimulating lipogenesis and de nov lipogenesis
and inhibits lipolysis

Question 8

synthase promotes

Answer 8

glucose storage

Question 9

phosphorylase inhibits

Answer 9

inhibits release of glycose from glycogen

Question 10

glucose appearance stimulates

Answer 10

hexokinase and glucokinase

Question 11

by stimulating hexokinase and glucokinase you promote

Answer 11

glycogenesis

Question 12

insulin decreases CAMP which causes

Answer 12

synthase to be active

Question 13

role insulin plays in glycogen metabolism

Answer 13

decrease CAMP and increase glycogenesis

Question 14

role of epi/ noriepinephrine role in glycogen metabolism

Answer 14

increase CAMP which stimulates phosphorylase

Question 15

more CAMP =

Answer 15

inhibits synthase

Question 16

less CAMP

Answer 16

you remove the inhibition on synthase

Question 17

glycogen synthase

Answer 17

turned on by insulin because less CAMP removes the inhibitions on synthase which makes more glycogen

Question 18

glycogen phosphorylase

Answer 18

turned on by glucagon, Epi/norepinephrine because it increases CAMP which stimulates synthase-promoting glycogenolysis

Question 19

insulin is an ____ hormone

Answer 19

anabolic (building)

Question 20

insulin on fat metabolism

Answer 20

decrease fat use as energy
-inhibit lipolysis
-increase fat storage = promotes lipogenesis and DNL

Question 21

risk factors that increase risk of CVD

Answer 21

-high total cholesterol
-high HDL
-high LDL
- high blood fat (dyslipidemia)

Question 22

good cholesterol is

Answer 22

HDL

Question 23

bad cholesterol is

Answer 23

LDL

Question 24

high-fat diet leads to

Answer 24

to more chylomicron which leads to VLDL which leads to LDL (endogenous and exogenous pathways)

Question 25

high starch/ sugar diet leads to

Answer 25

hyperglycemia which leads to hyperinsulinemia which leads to stimulation of lipogenesis which = more fat and LDL

Question 26

the amount of new fat made from CHO depends on

Answer 26

severity of excess CHO (intensity of insulin effect), consistency of excess CHO intake (consistency of insulin effect), and glycogen fullness when excess CHO is consumed
