Energy Systems

Question 1

ATP

Answer 1

adenosine triphosphate

Question 2

limiting factors of lactic acid system

Answer 2

glycogen stores are limited, rapid use of glycogen to make ATP produces lactic acid

Question 3

lactic acid system used for

Answer 3

weight training or sprinting

Question 4

lactic acid (anaerobic system)

Answer 4

glycogen stored in muscle is broken down to remake ATP sans o2
provides energy for 1-3 minutes

Question 5

anaerobix

Answer 5

without o2

Question 6

how long does it take to regenerate creatine phosphate

Answer 6

2+ mins

Question 7

limiting factor of CP system

Answer 7

levels of CP are low

Question 8

PC system is predominant for

Answer 8

explosive sports

Question 9

Pc system

Answer 9

phosphate bond is broken down and used to resynthesize ATP

-used for instantaneous bursts of energy

Question 10

creatine phosphate

Answer 10

high energy compound stored in muscle

Question 11

3 energy system

Answer 11

Phosphocreatine System, anaerobic/lactic acid system, aerobic system

Question 12

protein

Answer 12

small contribution to energy production, provides energy at a slower rate than carbs

Question 13

fats stored as

Answer 13

triglycerides

Question 14

carbs

Answer 14

form of glucose
body’s preferred source of food energy
breakdown of glycogen stored in muscles and liver cells

Question 15

where does energy come from

Answer 15

carbs, fats and proteins

Question 16

only enough energy in ATP for

Answer 16

4 seconds

Question 17

ATP loses a phosphate

Answer 17

energy is releases and heat is given up, leaves behind ADP, breakdown to resynthesize ATP

Question 18

if lactic acid production exceeds removal

Answer 18

muscles become fatigues and muscle contraction is impeded

Question 19

how to reduce lactic acid

Answer 19

reduce intensity to allow o2 to be available to muscles, allows LA to be transported to liver

Question 20

LA is converted in liver to

Answer 20

glucose

Question 21

aerobic system

Answer 21

re-synthesizes ATP with o2 and fatty acids

amino acids can also be used when carb stores are low

Question 22

where does aerobic energy production take place

Answer 22

mitochondria

Question 23

byproducts of aerobic system

Answer 23

sweat and co2

Question 24

which fuel is best for high intensity

Answer 24

carbs

Question 25

which fuel for low intensity and endurance

Answer 25

fat

Question 26

Food breakdown into energy

Answer 26

food > digestion > absorbed into blood > transported > active cells > immediate use

Question 27

carb breakdown into energy

Answer 27

carb >glucose > stored as glycogen > ATP

Question 28

fat breakdown into energy

Answer 28

fat > fatty acids > stored as adipose tissue > ATP

Question 29

protein breakdown into energy

Answer 29

protein > amino acids > growth and repair of tissues (stored as fat) > ATP

Question 30

what are the waste products of the CP system

Answer 30

none
