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.

- Select the CORRECT description of the peptide bond. The peptide bond can freely rotate around the peptide bond. The peptide bond is non-polar, hydrophobic and does not have a dipole. The peptide bond is most stable in the cis configuration. The peptide bond is rigid and planar. The peptide bond has a mix of single and double bond characters. The peptide bond is most stable in the trans configuration.arrow_forwardBelow is a fractional saturation curve for O2 binding to adult hemoglobin.
