Energy Systems Exam Questions And
Answers 100% Pass.
The energy our bodies use comes directly from the nutrients in the food we eat, especially
carbohydrates. Into which universal form of energy are these nutrients reconstituted for use in
muscle contraction and other physiological processes? Describe the final form of this common
form of energy at the molecular level. - Answer✔The final form this free energy takes is
adenosine triphosphate, ATP- the common energy molecule for all living things. ATP captures
the chemical energy resulting from the breakdown of food and is then used to fuel the various
cellular processes in our bodies
List and briefly describe the two energy systems and the three metabolic pathways by means of
which ATP energy reserves are restored in the body. - Answer✔Two energy systems: Anaerobic
and aerobic systems
Three metabolic pathways: ATP-PC (anaerobic alactic), Glycolysis (anaerobic lactic) and
Cellular respiration
The two anaerobic energy pathways are sometimes referred to as "lactic" and "alactic". Write a
clear definition for each of these terms. - Answer✔Alactic: This energy system is the first one
recruited for exercise and it is the dominant source of muscle energy for high intensity explosive
exercise that lasts for 10 seconds or less.
Lactic:This system is the dominant source of muscle energy for high intensity exercise activities
that last up to approximately 90 seconds.
All sports generally involve all three metabolic pathways, but often one pathway can be
considered the predominant one for that sport. For each of the three metabolic pathways, list
three examples of sports that rely primarily on that pathway. - Answer✔ATP-PC (anaerobic
alactic): 100m Sprint, weight lifters (heavy), golfers, home run hitters
Glycolysis (anaerobic lactic):Rowing, cycling, hockey
Cellular respiration: Biking, skiing, swimming
Exercise physiologists distinguish between two general types of muscle fibre. Identify each type
and state the main difference between them. - Answer✔Slow twitch: -Dark in colour
-generates/relaxes tension slowly
