Question 1

What is the first step of co transport?

Answer 1

• sodium potassium pump
• sodium ions pumped out of cell to blood (against concentration gradient)
• low concentration of sodium ions in cell

Question 2

What is the second step of co transport?

Answer 2

• co transporter carrier proteins allow 2 molecules in
• sodium ions and glucose/amino acid

Question 3
