Question
Complete the following statements by choosing the correct response from the key choices and entering the appropriate letter or term in the answer blanks. Key Choices Fatigue Isotonic contraction Muscle cell Muscle tone Isometric contraction Whole muscle Few motor units Many motor units Repolarization Depolarization ______________ ________ is a continuous contraction that shows no evidence of relaxation _______ A(n) _________ is a contraction in which the muscle shortens and work is done. ______ To accomplish a strong contraction, ___________ are stimulated at a rapid rate. __________ When a weak but smooth muscle contraction is desired. ___________ are stimulated at a rapid rate. ___________when a muscle is being stimulated but is not able to respond due to "oxygen debt, " the condition is called ___________ A(n) ________ is a contraction in which the muscle does not shorten but tension in the muscle keeps increasing. The terms in the key refer to the three ways that muscle cells replenish their ATP supplies. Select the term(s) that best apply to the conditions described and insert the correct key letter(s) in the answer blanks. Key Choices Coupled reaction of CP and ADP Anaerobic glycolysis Aerobic respiration __________ Accompanied by lactic acid formation ___________ Supplies the highest ATP yield per glucose molecule ___________ Involves the simple transfer of a phosphate group __________ Requires no oxygen __________ The slowest ATP regeneration process __________ Produces carbon dioxide and water ___________ The energy mechanism used in the second hour of running in a marathon ___________ Used when the oxygen supply is inadequate over time ________ Good for a sprintExplanation / Answer
6.1. ANS: G. Tetanus
Tetanus is a continuous contraction that shows no evidence of relaxation
6.2. ANS: B. Isotonic concentration
An isotonic concentric contraction results in the muscle shortening, an isotoniceccentric contraction results in the muscle lengthening. During an isometric contraction the muscle is under tension but neither shortens nor lengthens.
6.3. ANS: I. Many Motor Units
Many Motor Units can accomplish a strong contraction; these are stimulated at a rapid rate.
6.4. ANS: H. Few motor units
When a weak but smooth muscle contraction is desired, few motor units are stimulated at a rapid rate
6.5. ANS: A. Fatigue
In fatigue muscle is being stimulated but is not able to respond due to oxygen debt
6.6. ANS: E. isometric contraction
In isometric contraction the muscle does not shorten but tension in the muscle keeps increasing.
A. Coupled reaction of creatine phosphate (CP) and ADP
B. Anaerobic glycolysis (Hear it is anaerobic fermentation, not anaerobic glycolysis Spelling mistake)
C. Aerobic respiration
7.1. ANS: B. Anaerobic glycolysis
7.2. ANS: C. Aerobic respiration
7.3. ANS: A. Coupled reaction of creatine phosphate (CP) and ADP
7.4. ANS: A. Coupled reaction of creatine phosphate (CP) and ADP, B. Anaerobic glycolysis
7.5. ANS: C. Aerobic respiration
7.6. ANS: C. Aerobic respiration
7.7. ANS: B. Anaerobic glycolysis
7.8. ANS: B. Anaerobic glycolysis
7.9. ANS: A. Coupled reaction of creatine phosphate (CP) and ADP
