B. Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
The respiratory system is one of the system in the body that play important role in maintaining acid-base balance in the body.
<em><u>The respiratory system enhances acid-base balance through the regulation of blood pH. It can reduce the pH of the blood by removing carbon dioxide gas in the blood.</u></em>
The regulation of Blood pH occurs as a result of chemical reactions that regulate the carbon dioxide levels and carbonic acid in the lungs when blood travels through the lungs.
