Answer 7

CHO is 4
Protein is 4
Fat is 9

Question 8

what are CHO converted to

Answer 8

glucose

Question 9

what is the primary atp substrate for muslces/brain

Answer 9

Carbohydrates

Question 10

how is glusocse stored in liver/muscles

Answer 10

as glycogen

Question 11

what does insulin do

Answer 11

promote the storage of glucose as glycogen because it takes out of glood to lower bloodsugar

Question 12

Answer 12

2,500 CHO
75,0000 fat

Question 13

what exercise type are fats used for

Answer 13

they are an energy substrate for prolonged, less intense exercise

Question 14

what are the 3 types of fats

Answer 14

unstarated (good), saturated (bad), and trans

Question 15

what are the building blocks for our muslces

Answer 15

proteins

Question 16

at what point is protein used as an energy substrate

Answer 16

during starvation

Question 17

what is gluconeogenesis

Answer 17

glucose creation from non-carbohydrates

Question 18

lipogenesis def

Answer 18

creation of fats/lipids from glucose

Question 19

alcohol kcal/gram?

Answer 19

7

Question 20

why isnt protein really used for energy?

Answer 20

it would have to break down muslces

Question 21

what are the 2 factors that control the rate of energy production

Answer 21

substrate availability
enzyme activity

Question 22

what is an enzyme do

Answer 22

facilitates the breakdwon of substrates
they do not start rxn’s but they do speed them up

Question 23

what 2 things affect enzymes

Answer 23

temperature and pH

Question 24

what breaks down ATP

Answer 24

ATPase

Question 25

what are the 2 ways to control the pathway

Answer 25

negative feedback loop botleneck of the pathway

Question 26

what does the negative feedback loop notion mean

Answer 26

that an excess of substrate feeds back to beginning to slow it down so there isnt too much

Question 27

what does the idea of the bottlneck refer to

Answer 27

the fact that the rate limiter is a way to control the rate of the pathway

Question 28

what is the point of breaking down ATP

Answer 28

to release energy

Question 29

how do you use by-products to synthesis ATP

Answer 29

ADP and Pi can be taken and made back into ATP because we dont store ATP

Question 30

what is hydrolysis

Answer 30

the breakdown of ATP when H2O is present
