D. oooooooooooooookkkkkkkkkkkk
It's letter C :) I think..
Answer:
The correct order is: 6) Sarcoplasmic reticulum releases calcium ions, 2) Calcium ions bind to troponin, 5) Tropomyosin moves to expose active sites of actin, 4) ATP is split into ADP and P, 1) Myosin head binds to actin, 7) ADP and P released from myosin, 3) Myosin cross-bridges bend, pulling actin toward center of sarcomere.
Explanation:
The ability to contract is an important property of the muscle cells and is fundamental to animals because muscles not only make locomotion possible but are also responsible for the correct functioning of organs (including the heart).
The mechanism behind muscle contraction is the sliding of filaments in a structure called sarcomere, which mostly involves the presence of actin and myosin filaments.
For muscle contraction to happen, there needs to be a <u>stimulus coming from the nerve that innervates said muscle</u>. This stimulus generates the release of <u>calcium ions</u> that will bind to a protein called troponin and will lead to the exposure of the active site of actin so it can bind to the myosin head. <u>This process requires ATP</u>.
The question offers an image containing information regarding the patient by the name of Anita and her actions prior to arriving at the hospital.
We can describe the patient and her timeline up to her hospital visit by mentioning information about her:
- <em>Name </em>
- <em>Occupation</em>
- <em>Weight</em>
- <em>Age</em>
- <em>Actions prior to her hospital visit</em>
The patient in question is a 108 pound, 36-year-old female by the name of Anita Martin. The patient is indicated to be a security guard. As per the information given, the patient seems to have been working a night shift in a building in the vicinity of a recent train wreck that seems to have released chlorine gas. On her way to her car, Anita was exposed to chlorine gas, due to which she decided to drive to the hospital.
With this information, we will have properly described the patient in question so that the medical professionals at the hospital will have all the information necessary to proceed with an effective treatment plan for Anita's condition.
