GRADE A+ 100% PASS GUARANTEE
at lower temperatures proteins are ___ - CORRECT ANSWER-slower
at higher temperatures proteins are ___ - CORRECT ANSWER-faster
what is a key distinction between prokaryotic and eukaryotic cell
membranes - CORRECT ANSWER-absence of sterol lipids (such as
cholesterol) which play a major role in eukaryotic membrane composition
organisms that have cell walls - CORRECT ANSWER-bacteria, plants, fungi,
algae
cell walls - CORRECT ANSWER-help to form shape of cell, rigid cant change
shape mostly, provides support, structure, and protection
cell envelope - CORRECT ANSWER-combination of the cell membrane and
the outer membrane (cell wall)
bacterial cell wall - CORRECT ANSWER-contains peptidoglycan
,peptidoglycan - CORRECT ANSWER-peptide- polysaccharide matrix, can
vary in thickness, essential for bacterial survival protects from
environmental stress
archaea cell walls - CORRECT ANSWER-lack peptidoglycan instead
composed of surface layer proteins S Layer
S layer proteins - CORRECT ANSWER-archaea cell wall, provide physical and
chemical protective barrier to harsh environments archaea is found in,
specific protein of S layer varies
yeast cell walls - CORRECT ANSWER-composed of mannoproteins
mannoproteins - CORRECT ANSWER-highly glycosylated polypeptides
called mannan and mannose
fungi cell walls - CORRECT ANSWER-cellulose and chitin
cell walls in eukaryotic cells - CORRECT ANSWER-varies
- polysaccharides- cellulose and pectin
- fungi- cellulose and chitin
- yeasts- mannoproteins
- algae- silica
, diatoms - CORRECT ANSWER-type of algae, have thick cell walls containing
silica
silica - CORRECT ANSWER-in cell walls of algae, found in glass, making
them very rigid
cytoplasm - CORRECT ANSWER-- open volume within a cell
- mostly water with dissolved substances
- organelles found here
organelles - CORRECT ANSWER-Structures specialized to perform distinct
processes within a cell
organelle in both eukaryotes and prokaryotes - CORRECT ANSWER-
ribosomes
organelle called the brain of the cell - CORRECT ANSWER-nucleus
___ is the defining organelle of all eukaryotic cells - CORRECT ANSWER-
nucleus
___ is the command center of the cell - CORRECT ANSWER-nucleus
genetic material of prokaryotic cells is found where - CORRECT ANSWER-
cytoplasm
