Question

The packaging of eatracellular materials in a vesicle at the cell surface for importation into the cell is called a) esmodi c) facilitated transportd) endoeytosis e) an ion exchange pump b) active transpont 47. The process by which vesicles containing solid objects such as bacteria are formed on the surface of a cell for transport into the cell is called a) pinocytosis b) phagoeytosis c) exocytosis d) receptor-mediated endocytosis e) none of the above 48. The principal cations in our body fluids are a) sodium, potassiurm c) sodium, magnesium e) sodium, chloride b) caleium, magnesium d) chloride, potassium ?. In order to preserve cellular homeostasis, an important exchange pump within the cell membrane ejectsons from the cell and importsons. a) potassium; calcium b) sodium; calcium c) potassium; sodium e) calcium; sodium d) sodium; potassium 50, The components of ribosomes are formed by a) the endoplasmic reticulum c) lysosomes e) nucleoli b) Golgi complexes d) mitochondria

Explanation / Answer

46-d - endocytosis

47-b- phagocytosis

48-a-sodium , potassium

49- c- pottasium , sodium

Note - the movement of any component from outside to inside wraped in cell membrane vesicle is called endocytosis and if it is exported outside it is exocytosis .

The cation extracelluarly is NA+ and cation intracellularly is k+
