Classify each membrane transport system as either a primary active transporter, a secondary active transporter, or a passive transporter. You should be able to answer these questions based on logic alone, even if you are not familiar with the details of these transporters. In biological systems, there are several membrane transport systems responsible for the passage of ions, such as Na^+ or K^+, or small molecules, such as glucose or amino acids, through biological membranes. the Ca^2+ ATPase of the sarcoplasmic reticulum the glucose transporter of erythrocytes the Na^+/K^+ ATPase of plasma membranes the glucose- Na^+ transporter of intestinal epithelial cells the amino acid-Na^+ transporter of kidney cells Which transport systems utilize a chemical reaction for the energy source?
