Answer: One of the most common Monera is Escherichia coli, also known as E. coli. "[E. coli] is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms." States wikipedia.* Signs of E. coli are stomach pains and cramps, diarrhea that may range from watery to bloody, fatigue, loss of appetite or nausea, vomiting, and low fever < 101 °F/ 38.5 °C (not all people have this specific symptom).

E. coli comes from human and animal wastes. During precipitation, E. coli may be washed into creeks, rivers, streams, lakes, or groundwater. Another way to get it is from contaminated food, a lot like corona virus. When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. And when ground beef is made, it combines meat from many different animals, increasing the risk of contamination.

Power stroke (myosin head bends) coupled with the release of ADP and phosphate, ATP hydrolyzed to ADP and Phosphate and the Myos

svetlana [45]

Answer:

Power stroke (myosin head bends) coupled with the release of ADP and phosphate

Explanation:

Muscle contraction results from myosin heads adhering to actin and attracting it inwards. It uses ATP. Myosin adhers to actin at a binding site of its globular actin protein and adheres at another binding site for ATP (hydrolyzed ATP to ADP, Pi and energy)

ATP binding prompts myosin to detach from actin, ATP is changed to ADP and inorganic phosphate, Pi by ATPase. The energy formed at this process orientates myosin head to a “cocked” direction.

The myosin head goes in the direction of the M line, holding the actin with it in the process causing the filaments to orientate nearly 10 nm in the direction of the M line--- power stroke (force is produced), the sarcomere reduces in length and the muscle contracts.

Note: The power stroke is seen when ADP and phosphate disattaches itself from the myosin head.

At the terminal point of the power stroke, the myosin head as low-energy, followed by ADP release.

The attached image shows the cross-bridge muscle contraction cycle, which is activated by Ca2+ sticking to the actin active site. And how actin moves in relation to myosin.
