Exercise Flashcards
1
Q
What four things does the metabolic response to exercise need to ensure?
A
increased energy supplies to muscle
rate of mobilisation equals rate of utilisation so you get minimal disturbances to the homeostasis of metabolism
glucose supply to brain maintained
products of metabolism removed as quickly as possible
2
Q
Describe the use of energy stores in exercise
A
2 secs- ATP
5 secs- Creatine phosphate
2mins- Glycogen
FAs
3
Q
Which two processes further supply energy? Explain why these are not suitaable for long exercise time
A
glycolysis- inefficient
oxidative phosphorylation- requires oxygen
4
Q
how is glycogen used for energy?
A
Glycogen converted to g6p for glycolysis by glycogen phosphatase
5
Q
Describe 5 hormones that respond to exercise?
A
Adrenaline-->increased glycogenolysis and lipolysis GH- Lipolysis Glucagon increases Insulin decreases Cortisol increases
