Question:

Which of the following is incorrect about muscle contraction?

A Actin and myosin filaments shorten during contraction.
Explaination

Muscle contraction occurs upon stimulation of neurotransmitters released in the neuromuscular junction. The process requires ATP and involves shortening of sarcomeres by the sliding of actin and myosin past each other. The length of actin and myosin filaments does not change during contraction.
