Question
For the following answer true or false please
79) The power stroke is generated during the latent phase.
80) Reformation of cross bridges occurs during the contraction-relaxation phase.
81) Creatine phosphate (phosphocreatine) carries extra oxygen in slow oxidative fibers.
82) Myosin gives fast oxidative fibers their characteristic color.
84) Fast oxidative fibers may develop more endurance with proper training and conditioning.
85) Creatine phospho-kinase attaches a phosphate group to creatinine.
86) A motor unit with one neuron per 10 muscle fibers will generate more precise movements than one
with one neuron per 100 muscle fibers.
87) Muscle cells replicate via mitosis after a good righteous workout.
88) Synergistic muscles work with each other.
89) Muscle tissue, like your lab instructor’s evil twin before his morning coffee, is irritable.
90) An Olympic class weightlifter would have mostly slow oxidative muscle fibers.
91) Myoglobin is an oxygen carrying protein.
92) Troponin prevents overstretching of myofibrils.
93) Reactive hyperemia results from oxygen starvation caused by an occluded blood vessel.
94) Active hyperemia results from exercise or other increased metabolic demand.
95) The parasympathetic nervous system speeds up the SA node.
Explanation / Answer
79) False, the power stroke is generated during the contraction phase of muscle twitch.
80) False crossbridge reform during contraction.
81) true.
82) True which is red in colour due myohaemoglobin.
84) True with proper training its possible.
85) True.

91) True
92) True.
93) True
94) True.
95) False the sympathetic nerves speed up SA node.
