WorksheetsThe Endomembranes of the Cell
Total questions: 15
Worksheet time: 8mins
The system of inter-connected membranes and organelles that work together to export proteins from the cell is called
the nuclear envelope matrix.
the endomembrane system.
the cytoplasm cytoskeleton.
the exomembrane skeleton.
Which of the following is NOT part of the endomembrane system?
The nuclear envelope
The cell membrane
The Golgi apparatus
The mitochondria
What type of cells contain the endomembrane system and organelles?
Prokaryotic cells only
Eukaryotic cells only
Both prokaryotic and eukaryotic cells
All cells
The packaging and shipping center of the cell, where small protein chains are combined to make larger proteins and then shipped out in vesicles is the
Endoplasmic Reticulum.
Lysosomes.
Vacuoles.
Golgi apparatus.
A small membrane-enclosed organelle that moves between organelles or out of the cell is called a
lysosome.
vesicle.
ribosome.
nucleosome.
Protein chains of amino acids are assembled in the
ribosomes.
lysosomes.
smooth ER.
Golgi apparatus.
The large storage organelle found mostly in plant cells is the
rough ER.
nuclear envelope.
Golgi apparatus.
vacuole.
Which of the following is NOT a function of the endomembrane system?
modification, packaging and transport of proteins
producing and transporting lipids
control of the hereditary information in the cell
breakdown of harmful pathogens in/around the cells
The main difference between smooth and rough ER is the presence of ____.
vesicles.
lysosomes.
enzymes.
ribosomes.
The smooth ER does all of the following EXCEPT
make proteins and enzymes for the cell to use.
make lipids, such as phospholipids and cholesterol for the cell.
detoxifies poisonous cell by-products to make them easier for the cells/body to remove.
stores calcium ions which are important in cell signaling.
Lysosomes contain
digestive enzymes.
DNA and RNA.
stored K+ and Na+ ions.
extra water for use by the cell.
If a lysosome ruptures/breaks open inside a cell, the cell will be 'safe' from the digestive enzymes because
lysosomes contain water that dilutes the cell.
the lysosome will have already been pushed out of the cell.
lysosomes contain lipids that won't react in the cell.
lysosomes have a very low pH; the higher pH of the cytoplasm inactivates the enzymes.
What is this structure in a cell?
the nucleus
the rough endoplasmic reticulum
the plasma membrane
the Golgi apparatus
Which cell structure was NOT involved in this process?
the cell membrane
a vesicle
a chloroplast
all of these structures were involved in this process
What is this cell organelle?
The Golgi apparatus
The Plasma membrane
The Nuclear membrane
The Endoplasmic Reticulum
