of other cells and with the immune system?Multiple choice question.:
Answer Glycoproteins
- Cells that contain membrane-bound organelles and a true nucleus are called cells:
- The movement of materials into or out of a cell without any energy expen- diture is called:
Answer Eukaryotic
Answer passive transport
13. The plasma membrane is composed of two layers of:
Answer Phospholipids
- The passive movement of materials from areas of higher concentration to areas of lower
concentration is called:
Answer Diffusion
- When materials move WITH their concentration gradient (from areas of high
concentration to areas of low concentration), it requires:
Answer no energy ex- penditure from the cell.
- the movement of materials down their concentration gradient into cells through the use
of special carrier or channel proteins is called:
Answer facilitated diffusion
- The phospholipids within the plasma membrane have two parts: a phosphate and
glycerol "head" and two fatty acid "tails." This structure contributes to its semi-permeable
nature.:
Answer hydrophilic; hydrophobic
18. Osmosis describes:
Answer the movement of water down its concentration gradient.
19. Diffusion is a passive process because:
Answer Both A and B are correct.
