Carbohydrates attached to lipids

A

Glycolipids

23
Q

Glyco means

A

Sugar

24
Q

Carbohydrates attached to proteins

A

Glycoproteins

25
Q

Glycolipid and Glycoprotein together

A

Glycocalyx

26
Q
  • Cushioning
  • Protection
  • Glue (attaches cells together)
  • Cell Recognition ( because of proteins since the functions of proteins are transport and receptors, it identifies if the cell should be there or not)

A

Hypertonic

40
Q
  • Shriveled/ Crenation in animal cell
  • Plasmolysis in plant cell
A

Hypertonic

41
Q
  • requires carrier proteins

A

Mediated Transport Mechanism

42
Q

a mediated transport process that requires energy provided by ATP.

A

Active transport

43
Q

a carrier mediated process that
move substance into or out of the cells
from a higher to a lower concentration

A

Facilitated Diffusion

44
Q

the internalization of substances, includes
both phagocytosis and pinocytosis

A

Endocytosis

45
Q

ENDOCYTOSIS refers to
the bulk uptake of material through the plasma
membrane by the formation of a

A

Vesicle

46
Q
  • Cell eating (solid particles)
  • important in the
    elimination of harmful substance from the
    body.
A

Phagocytosis

47
