Energy Systems Revision

The source of energy for muscle contraction is ________

• Alactacid System

• Lactic Acid

• Carbohydrates

• Adenosine Triphosphate (ATP)

How many energy systems are there?

• 1

• 2

• 3

• 4

Which system provides immediate energy for a very short time?

• ATP/PC

  Alactacid System

• Lactic Acid System

• Aerobic System

• Anaerobic Glycolysis

The lactic acid system provides endless energy at a slow rate.

• True

• False

Answer explanation

False. The Lactic Acid system provides energy for less than one minute of high intensity exercise and up to three minutes for lower intensity exercise.

The fuel source of the lactic acid system is ________

Which of the following is a by-product of the ATP-PC system?

• water

• lactic acid

• glycogen

• There are no by-products of this system

Which system uses carbohydrates and fat as the fuel source?

• Lactic Acid System

• Aerobic System

• ATP-PC System

• None of these options

Which of these are by products of the Aerobic energy system?

• There are no by-products

• Carbon Dioxide

• Water

• ATP-PC

Name an essential process in the body at rest that requires energy for maintenance (one word)

Answer explanation

The body has a constant need for energy.  Even at rest, there are essential body processes that need to be maintained – respiration, circulation, digestion. These all require energy to happen.

Energy production is the conversion of ____________

• chemical energy to mechanical energy

• mechanical energy to chemical energy

Answer explanation

The basic process of energy production involves the conversion of chemical energy, (taken into body in the form of food), into mechanical energy, (in the form of muscular contraction and movement).
