What ions, ATP, and neurotransmitters are used in muscle contraction and where are they used??

vivado [14]

Answer:

Hiya there!

Explanation:

ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site. ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur.

acetylcholine : Skeletal muscle contraction and changes with exercise. (A) Neurotransmitter (acetylcholine, ACh) released from nerve endings binds to receptors (AChRs) on the muscle surface.

The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. As soon as the actin-binding sites are uncovered, the high-energy myosin head bridges the gap, forming a cross-bridge.

How is The environment on Mars different from that of Earth’s?

Pavlova-9 [17]

Answer:

Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth's. The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide.
The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth's is rich in nitrogen and oxygen.
Because of the differences in atmospheric densities and distances from the sun, the temperature within the atmosphere are also wildly different. Earth generally ranges from 14 degrees Celsius to 70.0 degrees, whereas Mars ranges from -146 degrees C to -140 degrees C.
Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.
Earth and Mars’ both have terrains that varies considerably from place to place.
