FA4 Flashcards
During surgery, exposed tissues are moistened with sterile Ringer’s solution to prevent shrinkage or lysis of the cells. Ringer’s solution must be ___ relative to cells in the tissue.
Isotonic
Which of the following substances requires a protein carrier in order to cross a membrane?
water, glucose, sodium ion, an amino acid
Plasmolysis occurs when a(n) __ cell is immersed in a __ solution.
plant; 3X saline
What is the difference between active transport (AT) and facilitated diffusion (FD)?
Active transport is an active process. Thus, it requires energy. Whereas facilitated diffusion is a passive process and does not require energy.
Active transport uses carrier proteins
Which two processes are most similar, differing only in the size of materials that are brought into the cell?
Pinocytosis and phagocytosis
Menstruation is an example of
Exocytosis
Which of the following statements is true for endocytosis?
a. it does not require energy
b. it helps in the intake of large materials by the cell
c. it occurs without the help of any cell organelle
d. it is a form of passive transport
it helps in the intake of large materials by the cell
Engulfing of bacteria by white blood cells is called as
phagocytosis
Cell eating is referred to as

C. Occurs without help of cell organelle
d. It does not require energy
Form of active transport
solution is one whose concentration is more than that inside the cell
