M4 - Membrane-bound Organelles (P2) Flashcards
Consists of single membrane and granular matrix scattered in the cytoplasm
Peroxisomes
Contain enzymes involved in a variety of metabolic reactions including several aspects of energy metabolism
Peroxisomes
Assembled from proteins that are synthesized on free ribosomes and then imported into (same as answer) as completed polypeptide chains
Peroxisomes - “…imported into peroxisomes…”
Involved in the production and elimination of hydrogen peroxide during biochemical processes and the oxidation of fatty acids
Peroxisomes
Surrounded by a membrane called tonoplast which encloses fluid containing inorganic materials like water and organic materials like nutrients and enzymes
Vacuole
Acts as a storage for nutrients as well as waste materials to protect the cell from toxicity
Vacuole
Helps in maintaining an acidic internal pH in cells by influx and outflow of H+ ions to the cytoplasm
Vacuole
For water storage
Vacuole
A membrane-bound organelle containing liquid or cytosol which is enclosed by a lipid bilayer
Vesicles
Facilitate the storage and transport of materials in and outside the cell
Vesicles
Allows the exchange of molecules between two cells
Vesicles
Site of photosynthesis
Chloroplast
Type of plastid that is involved in photosynthesis in plants and algae
Chloroplast
Contains high concentration of chlorophyll that traps sunlight
Chloroplast
Has its own DNA and can reproduce independently from the rest of the cell
Chloroplast
Has two distinct regions, namely grana and stroma
Chloroplast
Consist of the chlorophyll pigments
Grana
Are the functional units of chloroplasts
Grana
The homogenous matrix which contains grana
Stroma
It is similar to the cytoplasm in cells in which all the organelles are embedded
Stroma
