Muscle Physiology and ATP Production Quiz

Which pathway produces ATP the fastest?

• Creatine phosphate pathway

• Anaerobic respiration

• Aerobic respiration

• Lactic acid fermentation

How many ATP are produced from one molecule of pyruvic acid during anaerobic respiration?

• 1

• 2

• 4

• 32

What is the main disadvantage of the creatine phosphate pathway?

• Slow ATP production

• Produces lactic acid

• Only produces 1 ATP per reaction

• Requires oxygen

Which muscle fiber type is associated with high endurance?

• Type 2

• Both Type 1 and Type 2

• Neither Type 1 nor Type 2

During aerobic respiration, how many ATP molecules are produced?

• 2

• 4

• 16

• 32

Which of the following muscle types is known for low endurance?

• Type 1

• Type 2

• Type 3

• Type 4

What occurs during the contraction period of a muscle twitch?

• Actin and myosin bind

• Muscle relaxes

• Sarcoplasmic reticulum pumps Ca++

• New stimulus is received

Which process converts lactic acid back into glucose?

• Glycolysis

• The liver

• Creatine phosphate pathway

• Tetany

The length-tension relationship refers to the:

• Duration of contraction

• Amount of tension produced depending on sarcomere length

• Speed of ATP production

• Color of muscle fibers

Which condition is defined as an uncontrolled muscle contraction?

• Twitch

• Spasm

• Tetany

• Wave simulation
