Energy Systems Flashcards
1
Q
Is the ATP/PC system anaerobic or aerobic? What is the fuel for the reaction? Where does it take place? What is the reaction yield? What is the reaction's by-product? How long does it last? What is the enzyme used in the reaction?
A
Anaerobic Phosphocreatine Muscle sarcoplasm 1:1 By- product= creatine Max 10 secs Creatine Kinase
2
Q
What is the reaction for the ATP/PC system?
A
PC --CK--> P + C + energy | | Coupled reaction | V energy + ADP + P --> ATP
3
Q
Is the Glycolytic system anaerobic or aerobic? What is the fuel for the reaction? Where does it take place? What is the reaction yield? What is the reaction's by-product? How long does it last? What is the enzyme used in the reaction?
A
Anaerobic Glycogen Muscle sarcoplasm 2:1 Lactic acid Max 180 seconds GPP, PFK, LDH
4
Q
What is the reaction for the Glycolytic system?
A
Glycogen --GPP--> glucose --PFK--> pyruvic acid + energy | | coupled reaction | V energy + ADP + P + ATP
5
Q
Is the Aerobic system anaerobic or aerobic? What is the fuel for the reaction? Where does it take place? What is the reaction yield? What is the reaction's by-product? How long does it last? What is the enzyme used in the reaction?
A
Aerobic Glycogen Muscle Sarcoplasm, Matrix of Mitochondria, Cristae of Mitochondria 1:38 Hydrogen and Oxygen 3 mins - 2 hours GPP, PFK, CoEnzymeA
6
Q
What is the reaction for the Aerobic energy system?
A
1) aerobic glycolysis
Glycogen –GPP–> glucose – PFK–> (as oxygen is present) pyruvic acid –CoEnzymeA–> Acetyl CoA
2) Krebb’s Cycle
Acetyl CoA + Oxaloacetic Acid = Citric Acid
Enters Krebb’s cycle and in a series of reactions is oxidised..
CO2 is produced and removed by expiration
Oxaloacetic acid is regenerated
2ATP
Hydrogen is released
3) electron transport chain
Hydrogen + NAD and FAD (hydrogen carriers) = NADH and FADH
Splits into electrons, ones carried by NAD provide 30 ATP and ones carried by FAD provides 4ATP
Hydrogen + + Oxygen = H20
