Question

Why is the mechanism of muscle contraction called ‘sliding movement’?

Answer 1

Sliding Movement:

Muscle contraction is the process of shortening of muscle fibre to facilitate movement. This contraction occurs due to the actin and myosin fibres which are discussed below:

• Actin is the protein that is thinner and myosin are thick protein bands.
• These Actin and myosin forms cross links when excited, and thereby initiates the sliding movement between the two filaments.
• This is called the theory of sliding mechanism of muscle contraction. Consumption of ATP are involved, making this process an active process.
