Topic 2.10 - Cell Compartmentalization 𖦹⋆｡°✩ Flashcards
what does a plasma membrane allow cells to establish
allows cells to establish and maintain internal environments that are different from their external environments
what else compartmentalizes the cell
eukaryotic cells have additional internal membranes and membrane-bound organelles
how do cellular compartments increase the efficiency of the cell
they allow for various metabolic processes and specific enzymatic reactions to occur simultaneously
true or false: the membrane minimizes competing interactions
true
in what environment do hydrolytic enzymes of the lysosome function
in an acidic environment
how does the inside of the lysosome maintain a more acidic pH despite the external environment remaining neutral
by having this compartmentalization, the inside of the lysosome can maintain a more acidic pH and allow for efficient hydrolysis to occur, while the rest of the cytoplasm can remain a more neutral environment
how does membrane folding allow for metabolic reactions to occur
by maximizing surface area
where do electron transport and ATP synthesis occur
in the inner mitochondrial membrane
what does folding of the inner membrane increase
increases the surface area, which allows for more ATP to be made
how does the folding of thylakoids affect the chloroplasts
the thylakoids are highly folded membrane compartments that increase the efficiency of light dependent reactions
