Anaerobic glycolytic system

Question 1

Anaerobic glycolytic
How is energy produced from this system?

Answer 1

Glycogen broken down by glycogen phosphorylase to produce glucose and glucose is broken down by phosphofructokinase to produce pyruvic acid
This produces 2 ATP
is insufficient O2 present, pyruvic acid broken down by lactate dehydrogenase to produce lactic acid

Question 2

anaerobic glycolytic
How long does it last for?

Answer 2

60-90s
Kicks in after ATP-PC

Question 3

Where is glycogen stored?

Answer 3

muscle/liver

Question 4

How many ATP molecules are produced by glucose?

Answer 4

2 ATP

Question 5

What does lactic acid result in?

Answer 5

diffuses into tissue fluid and blood
if not removed, builds up to impede muscle contraction and causes fatigue

Question 6

anaerobic glycolytic
How long is recovery time?

Answer 6

approx 8 minutes

Question 7

What are the advantages?

Answer 7

high intensity
no delay in O2 delivery

Question 8

What are the disadvantages?

Answer 8

short duration
by-product of lactic acid
low energy yield 1:2
