Energy Systems Exam Questions And
Answers 100% Pass.
What are the 3 main energy systems used by the human body? - Answer✔1) Phosphagen system
2) Glycolysis system (lactic acid)
3) Aerobic system
What does ATP and ADP stand for? - Answer✔Adenosine triphosphate and Adenosine
diphosphate.
How long do the different energy systems last and what activities would use each system? -
Answer✔Phosphagen system - 8-10s - 100m sprint, powerlifting
Glycolysis system - 1.3-1.6mins - 400m swim, 800m race
Aerobic System - unlimited - marathon
How does our muscle use ATP? - Answer✔When the ATP molecule is combined with water
(hydrolysis) the last phosphate group splits away and releases energy, that molecule then
becomes ADP, then to replenish ATP a chemical reaction adds a phosphate group to ADP
(phosphorylation). If this occurs in the presence of oxygen it is an aerobic reaction if it occurs
without oxygen it is an anaerobic reaction.
What are the 2 energy systems that work without oxygen? - Answer✔Phosphagen System
Glycolysis System
What does the Glycolysis system use for fuel? - Answer✔Blood glucose or stored glycogen.
What is the basic process of the Glycolytic system? - Answer✔The body puts either blood
glucose or stored glycogen through 10 steps where energy is released creating more ATP until
the glucose is converted to pyruvic acid. Pyruvic acid is then stabilized into lactic acid.
What is the basic process of the Aerobic system? - Answer✔Carbohydrates, Fats and proteins go
through the Krebs cycle stripping molecules for use in the Electron Transport Chain where
energy is released.
What is the basic process of the Phosphagen System? - Answer✔Phosphate and creatine
molecules combine with energy to become PCr, muscles use the energy which splits the PCr
