Energy Systems revision

What does ATP stand for in the context of energy for muscular contractions?

• Adenosine diphosphate

• Adenosine triphosphate

• Adenosine tetraphosphate

• Adenosine monophosphate

What is released when ATP loses its third phosphate (Pi)?

• Water

• Oxygen

• Energy

• Carbon dioxide

How many food fuels are broken down to release energy for ATP resynthesis?

• 1

• 2

• 3

• 4

Which fuel source is preferred at rest or low intensities?

• Carbohydrates

• Proteins

• Fats

• Sugars

Why are fats preferred as a fuel source at rest or low intensities?

• They produce ATP at a faster rate

• They have a higher yield of ATP

• They are easier to digest

• They are stored in the liver

What process involves the breakdown of lipids to release energy?

• Glycolysis

• Lipolysis

• Hydrolysis

• Photosynthesis

Which fuel source is preferred during exercise?

• Fats

• Proteins

• Carbohydrates

• Vitamins

Why are carbohydrates preferred as a fuel source during exercise?

• They produce ATP at a faster rate due to fewer chemical reactions

• They have a higher yield of ATP

• They are stored in muscles

• They are easier to digest

Which of the following is stored as glycogen in the liver and muscles?

• Protein

• Fat

• Carbohydrates

• Creatine phosphate

Which of the following is rarely used as a dominant fuel source?

• Carbohydrates

• Fat

• Protein

• Creatine phosphate
