Energy Systems

Question 0

creatine phosphate system is the main source of energy during blank exercise

Answer 0

intense

Question 1

phosphocreatine plus adp equals

Answer 1

creatine plus atp

Question 2

creatine phosphate system releases energy in less than blank and lasts for about blank

Answer 2

10 seconds, 20-30 seconds

Question 3

the creatine phosphate system restores itself within blank

Answer 3

a few minutes

Question 4

once PCr is used to create ATP, the remaining creatine goes to the mitochondria where it picks up another Phosphate

Answer 4

creatine phosphate shuttle

Question 5

anaerobic metabolism where energy is supplied from glucose or stored glycogen within the muscle

Answer 5

lactic acid system

Question 6

lactic acid system provides energy during maximal exercise that lasts between blank

Answer 6

60-180 seconds

Question 7

lactic acid system is aka

Answer 7

glycolysis

Question 8

GLYColysis is a blank step process that breaks down glucose

Answer 8

10

Question 9

glycolysis yields about fiver percent of the total energy from one glucose molecule

Answer 9

5% (2-3 ATP)

Question 10

rate limiting enzyme used in converting fructose 6 phosphate to fructose 1,6 diphosphate

Answer 10

phosphofructokinase

Question 11

net products of glycogen

Answer 11

2 atp, 2 nadh

Question 12

compound that eventually forms pyruvate

Answer 12

fructose 1,6 diphosphate

Question 13

high amounts of oxygen inhibits blank

Answer 13

glycolysis

Question 14

serves as an anergy source during the recovery from exercise

Answer 14

lactate formation

Question 15

lactate is used as a source of energy by the blank blank and blank

Answer 15

liver, kidneys, heart

Question 16

signifies the onset of appreciable lactate formation in muscle cell

Answer 16

lactate threshold

Question 17

increase in the amount of lactate lowers the blank of blood

Answer 17

ph

Question 18

sharp increase in lactate levels

Answer 18

lactate threshold

Question 19

untrained individuals reach the blank at an earlier percentage VO2 max

Answer 19

lactate threshold

Question 20

primary means of energy production at rest

Answer 20

aerobic system

Question 21

aerobic metabolism provides nearly all of the energy transfer when exercise continues beyond blank

Answer 21

several minutes

Question 22

RQ at rest

Answer 22

.75 - .82

Question 23

oxygen consumption rises exponentially during the blank of exercise before it blank for the duration of the effort

Answer 23

first minutes, stabilizes

Question 24

there is an oxygen blank in the early stages of aerobic exercise

Answer 24

deficit

Question 25

coupled with the electron transport chain, blank synthesiszes atp by transferring electrons from nadh and fadh2 to oxygen

Answer 25

oxidative phosphorylation

Question 26

the majority of atp is generated by the large amount of blank created during the citric acid cycle and oxidized via the aerobic process of the ETC

Answer 26

hydrogens

Question 27

coupling the citric acid cycle and the electorn transport chain nets a total of blank atp

Answer 27

32
