How is the energy in ATP released so that it may be used to drive cellular processes?

Kitty [74]

All life depends on capturing energy from the sun and converting it in to a form that living organisms can use.
- Two key processes (mirror each other)
- Photosynthesis (Sun -> Plants)
- Cellular respiration (Plants/Animals/energy)

Using the sliding flament theory, explain (or draw) the process of sarcomere shortening. Start from the point where calcium woul

Arte-miy333 [17]

Answer:

Calcium binds to troponin C
Troponin T moves tropomyosin and unblocks the binding sites
Myosin heads join to the actin forming cross-bridges
ATP turns into ADP and inorganic phosphate and releases energy
The energy is used to impulse myofilaments slide producing a power stroke
ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
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 calcium into the sarcolemma. 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.

Which of the following cranial nerve numbers match with their names correctlt.

Cloud [144]

Answer:

c. Cr. N. IV = trochlear nerve

Explanation:

The IV cranial nerve is the trochlear nerve. It is located on the dorsal side of the brain near the back. It is a motor nerve and the smallest nerve which serves eye. This nerve present in the superior oblique muscle of the eye. The superior oblique muscle controls the rotational movement of the eyeball and prevent the eyeball from rolling upward into the eye socket.
