Concept explainers
(a)
To explain: Whether the phosphate transporter membrane protein functions more like KscA or GLUT1.
Concept introduction: Membrane proteins are the proteins present at the membrane of cell that interact with the biological membrane and with the ions. Membrane proteins are mainly of two types: transporter protein and membrane receptor. Transporter proteins are the proteins that move the molecules and ions across the membrane.
(b)
To explain: The transport system of phosphate ions that enter the cell along with the H+ ion.
Concept introduction: Membrane proteins are the proteins present at the membrane of cells that interact with the biological membrane and with the ions. Membrane proteins are mainly of two types: transporter proteins and membrane receptors. Transporter proteins are the proteins that move the molecules and ions across the membrane.
(c)
To explain: Whether the variation of pH in both sides of the cell would suggest that the transporter carries out secondary transport.
Concept introduction: Membrane proteins are the protein present at the membrane of cells that interact with biological membrane and with ions. Membrane proteins are mainly of two types: transporter protein and membrane receptor. Transporter proteins are the proteins that move the molecules and ions across the membrane.
