The power stroke corresponds to which event in muscle contraction?.

Answers

Answer 1

Answer: sliding of actin relative to myosin filaments

Explanation:

Answer 2

The power stroke corresponds to the event in muscle contraction where the myosin heads of the thick filaments in the sarcomere of a muscle fiber bind to and pull the thin filaments (actin) towards the center of the sarcomere.

During muscle contraction, the myosin heads undergo a series of events known as the cross-bridge cycle. The power stroke is a crucial step in this cycle. It occurs when the myosin heads, which are initially in a high-energy, cocked position, bind to actin filaments. The energy is then released, causing the myosin heads to change their orientation and pull the actin filaments inward, generating force and shortening the sarcomere.

The people in his family tend to be larger than average, and Elliot's weight  is above average. Should Elliot be considered fit Yes, fitness is about having an active, healthy lifestyle. Option first is the correct answer.

A healthy active lifestyle is a way of living that includes frequent exercise and nutritious eating to improve overall health. It's not about gaining peak performance or elite athlete status.

Physical activity can help you regulate your weight, reduce your risk of disease, strengthen your bones and muscles, and increase your ability to do daily tasks.

Fitness has five components: (1) body composition, (2) flexibility, (3) muscular strength, (4) muscular endurance, and (5) cardio-respiratory endurance. A well-balanced exercise regimen should include exercises that address all aspects of fitness that are related to health.
