Question

Many amino acids in our diet are absorbed via the transcellular transport pathway by the intestinal eprthellal cells. This process requires ATP hydrolysis by ... the apical do the Na -a no acid symporters the plasma membrane. Na -a acid antiporters in the apical domain of the plasma membrane. The amino the Na pumps in the basolateral plasma membrane. the amino acid the basal domain of the plasma membrane F-type ATases In the a domain of the plasma membrane. An ion channel ... always mediates passrvo transport. is typically several orders of magnitude faster than atransporter. is usually gated. Al of the above For each membrane protein in the following schematic drawings, indicate whether the cytoplasmic sideof the membrane is more likely to be on the left or on the rignt. The plasma membrane is indicated as grey bar.

Answer 1

Please find the answers below:

Answer 1: Choice 3 (the trans-membranous sodium-potassium pump refers to the system of transportation of materials across the membrane by utilization of energy in the form of ATP)

Answer 2: Choice 5 (the ion channels, such as calcium channels, sodium channels etc are extremely fast operated with presence of gating proteins in their co-locality. These channels follow passive transport of ions across the membrane according to the volate gated proteins and the concentration gradient)

Answer 3: Choice 1 (The anchor proteins remain spanning the transmembrane with the larger side on the extracellular space. The fatty acids too are generally protruded out of the membrane towards the extracellular space as the ligand proteins)
