1 answer:

7 0

<span>No. Protein is an important component of every cell in the body. Hair and nails are mostly made of protein, the body uses protein to build and repair tissues as well as to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.</span>

What manages muscles and prevents injury by monitoring the rate of muscle contraction?

IgorLugansk [536]

Golgi tendon organ manages muscles and prevents injury by monitoring the rate of muscle contraction.

What is the Golgi tendon organ? What is its primary function?

Sensory organs called Golgi tendon organs (GTOs) are found in the tendon next to the myotendinous junction. The Golgi tendon organ, which is located close to the point where a tendon joins a muscle, is a sensory ending that resembles a tree and is encased in a spindle-shaped connective tissue capsule.

The Golgi tendon organ is the sensory organ that determines how much tension the muscle is exerting when someone lifts weights. The Golgi tendon organ will prevent the muscle from producing any force (by a reflex arc) if there is excessive muscle tension, preventing you from harming yourself. Together, these monitor muscle length via the muscle spindles.

In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation

Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.

These fibers have the ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.
