Gross Contraction and Energy for Contraction Quiz

What does Muscle Tension refer to?

• The continuous and passive partial contraction of the muscles

• The primary energy currency of the cell

• The strength of a muscle's contraction in response to demands

• The force generated by a muscle when it contracts

What is Muscle Tone?

• The force generated by a muscle when it contracts

• The rapid means of energy production

• The continuous and passive partial contraction of the muscles

• The strength of a muscle's contraction in response to demands

How is Graded Response achieved?

• By the depletion of glycogen stores

• Through changes in the frequency of stimulation or the number and size of motor units being activated

• By the accumulation of lactate and hydrogen ions

• Through the continuous and passive partial contraction of the muscles

What is the primary energy currency of the cell?

• ATP (Adenosine Triphosphate)

• Lactate

• Glycolysis

• Creatine Phosphate

Which molecule donates a phosphate group to ADP to rapidly replenish ATP?

• Creatine Phosphate

• Glycogen

• Pyruvate

• Lactate

What is Glycolysis?

• An anaerobic process that breaks down glucose into pyruvate

• The primary method of energy production during prolonged activities

• The force generated by a muscle when it contracts

• The continuous and passive partial contraction of the muscles

What does Anaerobic Respiration produce?

• CO2 and water

• A significantly greater amount of ATP

• Lactate and hydrogen ions

• Creatine Phosphate

What is the primary method of energy production during prolonged activities?

• Aerobic Respiration

• Creatine Phosphate

• Glycolysis

• Anaerobic Respiration

What can cause muscle fatigue during prolonged or intense activity?

• Continuous and passive partial contraction of the muscles

• Rapid means of energy production

• Accumulation of metabolic byproducts

• Changes in the frequency of stimulation

In order for muscle contraction to occur, the muscle fiber requires calcium, as well as this substance which provides the cell with energy:

• ATP

• Epinephrine

• Bicarbonate

• Lipase
