Consider the following statements about the sliding filament theory of muscle contraction: a. This theory explains the modern concept of muscle contraction. b. This theory was put forward by Huxley and Niedergerke. Which of the above statements is/are true? Correct Answer Both a and b

The correct answer is Both a and b.

Key Points

  • The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement.
  • This theory was put forward by Huxley and Niedergerke in 1954.
  • Hence the correct answer is Both a and b.

Important Points

  • The Sliding Filament Theory
    • In 1954, scientists published two groundbreaking papers describing the molecular basis of muscle contraction.
    •  Using high-resolution microscopy, A. F. Huxley, and R. Niedergerke (1954) observed changes in the sarcomeres as muscle tissue shortened. (A sarcomere is a complicated unit of striated muscle tissue.)
    •  These observations led them to propose the sliding filament theory, which states that the sliding of actin past myosin generates muscle tension.

Which of the following is NOT true about Frictional force? A. Friction is the force which opposes the relative motion of two surfaces in contact. B. The force of friction that acts when a body is moving (sliding) on a surface is called sliding friction. C. Friction in machines wastes energy and also causes wear and tear. D. Rolling friction is much more than sliding friction, the use of ball bearings in a machine considerably reduces friction.
