QUALITY
what role do proteins play in living systems? - ---Answers---
--structural
-regulatory (signalling)
-contractive(movement)
-immunological(antibodies)
-carrier(hemoglobin)
-catalytic(enzymes)
denaturation of enzymes - ---Answers----when an enzyme
loses its 3D structure
denaturation of functional proteins - ---Answers----easily
denatured
denaturation of structural proteins - ---Answers----do not
denature easily
DNA - ---Answers----in nucleus of cell
-genetic material
-contains genes

,-sugar is deoxyribose
-nucleotides
RNA - ---Answers----directly codes for nucleotides
-single stranded
-ribose
-slightly different nucleotide sequence
cell theory - ---Answers-----cell is structural functional unit
of life
-activity of organism is combined results of the cell
-activity of each individual cell depends on sub cellular
composition
-cells come from other cells
ATP - ---Answers----amine bound to phosphate in which 2
additional phosphates have been added
fluid mosaic model - ---Answers----proteins are impeded in
the plasma membrane and float around "fluidly"
