Which of the following transporters is considered the most i

Which of the following transporters is considered the most important transporter in the cell, and uses up approximately 30% of the cellular ATP to function? Integrins Connexins GLUT Na^+/K^+ ATPase Na^+/glucose transporter (SGLT) During a recent visit to the family physician, a young man is told that based on the lesions on his skin (see above) that it is likely that he has developed Pemphigus vulgaris. Because you took Mammalian physiology, you know that this means that his immune system is attacking his: Cadherins Desmosomes Integrins Lysosomes Peroxisomes In the following diagram, during which state is a cell experiencing repolarization? A B C D None of the above Which of the following transporters is considered the most important transporter in the cell, and use up approximately 30% of the cellular ATP to function? Integrins Connexins GLUT Na^+/K^+ ATPase Na^+/glucose transporter (SGLT) Which of the following transporters is a secondary active transporter? Integrins Connexins GLUT Na^+/K^+ ATPase Na^+/glucose transporter (SGLT)

Solution

43. Na⁺/K⁺ ATPase is an enzyme present on the plasma membrane . it is a transporter of pumping 3Na⁺ out of the cell and 2 K⁺ ions into the cell. in this procees is active transport means Na⁺/K⁺ ATPase  Hydrolysis 30% of .ATP in the cell and releases energy gradient in the cell it may be utilized by Na⁺ / Glucoe transporters. for transporting glucose into the cell by gradient concentration of Sodium ions out side the cell. because Glucose enter along with the sodium ions into the cell.

44. Pamphigus vulgaris is skin disease caused by producing own antibodies towards desmosomes. and it is also called autoimmune disease.

45. In graph Area B is actually repolarization. during repolarization cell becomes normal negative charge. -70 to 90mv. while depolarization Sodium entere in to the cell then cell becomes positive . when sodium is more in side the cell it leads to opening of pottasium channals. loss of pottasium from the cell leads to the cell becomes to resting potential. becoming resting potential is called repolarization.

46 and 43 are similar questions

47. Na⁺ / Glucoe transporters.are secondary active transporters. they transpor glucose into the cell by gradient concentration of Sodium ions out side the cell. because Glucose enter along with the sodium ions into the cell.these are called co transporters.
