Answer :
The answer is That percentage of composition of Zinc as determined said to be 19%, the percentage of iodine 81% and it shows that it is very close to accepted values by making calculations.
Explanations:
When iodine is dissolved in a strongly polar substance such as menthol. As the reaction is progressed, the color of the solution going from its initial color. Furthermore, after the reaction, small grey pallets supports the percentage between iodine reacted with the zinc. All the iodine reacted whereas portion reacted while the rest remained untouched.
Lactate is produced by fermentation
A Protein Pump :- Protein pumps use energy from hydrolysis of ATP to move ions or large molecules across cell membrane.
Purpose of a Protein Pump :- In a Protein Pump the proteins help in active transport of molecules. Example, Membrane proteins are very specific and help in active transport. These proteins are positioned to cross the membrane so one part on the inside of the cell and one part is on the outside of the cell. Only when they cross the bilayer(cell membrane) they are able to move molecules and ions in and out of the cell.
Need for a Protein pump to work :- In active transport, A protein pump changes its shape when allows movement of molecules and therefore requires energy in the form of ATP. They use the energy of ATP hydrolysis to move ions or small molecules across a membrane.
