Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
Answer:
Hi there, the answer is energy
Explanation:
Carbon dioxide, oxygen, and water are all products of cellular respiration in fact carbon dioxide and oxygen are extremely important for ATP. If you are talking about aerobic respiration oxygen is the main product for it because it reacts to glucose. The only thing that isnt part of the product of cellular respiration is energy. After ATP is created for the plants it makes its own energy afterward.
Hope this helped :)
