Muscle

Question

Which of the following is not a characteristic of muscle contraction?

Easy

A

The I-bands and H-zone of a sarcomere shorten during contraction.
B

Calcium ions are required for unmasking the active sites for myosin.
C

Repeated contraction can result in accumulation of lactic acid.
D

Troponin subunits present in the thick filament bind to calcium ions.

Solution

Increase in Ca⁺⁺ level leads to the binding of calcium with a subunit of troponin of thin filaments and thereby remove the masking of active sites for myosin.
