If the na+ voltage-gated channels in a muscle cell open, what will be the result?
sammy [17]
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.

Removes carbon from air: photosynthesis by plants and algae
Release of carbon into atmosphere: respiration (animals exhale CO2), factory emissions, eruption of volcanoes, hydrothermal vents, and breakdown of organic matter
Release of carbon into the soil: Shells of marine organisms form limestone, and some carbon from decomposing organisms is stored in the soil
*This isn’t every possible pathway but hopefully this will help get you started. I’m going to attach a picture of the carbon cycle (not mine) to help you visualize the process.
