Question 22

Electron transport chain/ oxidative phosphorylation anaerobic or aerobic

Answer 22

aerobic

Question 23

Electron transport chain/ oxidative phosphorylation fuel

Answer 23

Question 24

Invertebrate or Vertebrate is able to tolerate total-body anoxia?

Answer 24

invertebrate

Question 25

Vertebrate Responses to hypoxia/anoxia

Answer 25

O2 regulation- attempt to extract more 02, up-regulate breathing rate,gill area,heart rate - not tolerable to total-body anoxia - O2 conform-metabolic depression - switches to anaerobic glycolysis - produce lactic acid/brain function

Question 26

Beginning of exercise what happens and follows?

Answer 26

start of exercise, oxygen demands goes up immediately but supply lags behind which causes "oxygen deficit"

Question 27

light exercise- oxygen demand, oxygen uptake, oxygen deficit and EPOC?

Answer 27

no lactic build up, small O2 def and EPOC, creatine/myglobin partially exhausted

Question 28

what kind of exercises shows Lactic buildup, larger o2 def/epoc, myglobin/creatine probably exhausted, steady state exercise ?

Answer 28

heavy exercise

Question 29

Supramaximal exercise-oxygen demand, oxygen uptake, oxygen deficit and EPOC?

Answer 29

lactic acid build up, huge o2 def/epoc, creatine/myglobin exhausted, non-steady state due to lactic acid accumulation

Question 30

Explain why particular mechanisms of ATP production dominate in different kinds of activity.

Answer 30

animals muscle use diff proportion of fuel sources at different times during exercise
