Using the sliding flament theory, explain (or draw) the process of sarcomere shortening. Start from the point where calcium woul
Arte-miy333 [17]

Answer:

  1. Calcium binds to troponin C
  2. Troponin T moves tropomyosin and unblocks the binding sites
  3. Myosin heads join to the actin forming cross-bridges
  4. ATP turns into ADP and inorganic phosphate and releases energy
  5. The energy is used to impulse myofilaments slide producing a power stroke
  6. ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
  7. ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
  8. Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Explanation:  

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing <u>calcium into the sarcolemma.</u> At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join to the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Bezzdna [24]

Answer:

Diffusion.

Explanation:

According to the information given before the example in the question and considering the fact that the bag was secured on both ends before being placed in the solution, provided that there were no holes on the surface of the bag, the iodine solution could have diffused through the bag into the starch solution hence the color change to black after 30 minutes.

I hope this answer helps.

Anna11 [10]
The appropriate response is Iron-fortified breakfast cereal or little measures of lean meat. Invigorated sustenances are nourishments to which additional supplements have been included. Cases of these supplements incorporate vitamin A, B vitamins, vitamin D, folic corrosive, iodine, and iron. The first reason for nourishment stronghold was to diminish the event of supplement inadequacies.
