I have to identify whether the following are primary active transport, secondary active transport, or passive transport. Then I have to decide what is the energy source: a chemical reaction, concentration gradient of cotransported ion, or conc gradient of transported solute.

Below are my answers, but I don't know if they are right. Thank you so much for ur help!

a) Na+/K+ ATPase of plasma membranes: primary active trans. and chemical reaction

b) glucose transporter of erythrocytes: passive and conc gradient of transported solute

c) amino-acid-Na+ trasporter of kidney cells: secondary active trans. and conc gradient of cotransported ion.

d) the glucose-Na+ transporter of epithelial cells: secondary active trans. and conc gradient of cotransported ion.

e) the Ca2+ ATPase of the sarcoplasmic reticulum: primary active trans and chemical reaction

Thank you again!
