Ans.
The membrane proteins that pump sodium ions out of the cell from inside and potassium ions inside the cells are called as sodium-potassium pumps or sodium-potassium ATPases.
These proteins perform active transport by using energy from ATP hydrolysis and transport two potassium ions inside the cells, along with transport of three sodium ions outside the cells, against the concentration gradient.
Thus, the correct answer to complete the sentence is sodium.

Answer:
Carbon is NOT found in proteins.
Explanation:
- In the carbon cycle, carbon is transferred or moved between the four reservoirs where it is in different states:
- Atmosphere, where it is in the form of carbon dioxide (CO2) by joining with oxygen in the form of gas.
- Terrestrial biosphere is found in the elements that make up terrestrial and coastal ecosystems, in non-living organic matter, and in the soil.
- Oceans, is part of the hydrosphere, is found in dissolved organic carbon, in marine organisms and in non-living matter.
- Sediments: it is part of the geosphere, it is found in fossils and fossil fuels.
