Mastering Biology Ch 4-2
(LABEL THE CHART) Can you trace the movement of proteins through the endomembrane system? Drag the labels onto the flowchart to trace the movement of proteins through the endomembrane system and out of the cell.
1. Manufacturing- Rough ER 2. Transport- Vesicle from ER 3. Processing- Golgi apparatus 4. Transport- Vesicle from Golgi 5. Secretion- Plasma membrane
Which one of the following lists the steps involved in the production of new proteins in the appropriate order and correctly describes each step?
DNA transfers information to mRNA...mRNA travels from nucleus to cytoplasm... ribosomes translate mRNA into proteins
A hormone that will be secreted from the cell is manufactured by ribosomes _____.
attached to the endoplasmic reticulum
Which organelle plays a role in intracellular digestion?
lysosome
Which of the following is a function of the Golgi apparatus?
protein modification
What structures move proteins from the ER to the Golgi apparatus?
transport vesicles
(MATCHING CHART) Can you identify the functions of the parts of an animal cell? Drag the correct description under each cell structure to identify the role it plays in the cell.
Nucleus- stores the genetic information of the cell Lysosome- breaks down macromolecules using digestive enzymes Mitochondrion- converts chemical fuel into packets of chemical energy that can power the cell Ribosome- works with mRNA to synthesize proteins Smooth ER- site of lipid synthesis
A plant cell has a versatile compartment that stores organic nutrients, absorbs water, and contains poisons that protect against plant-eating animals. This compartment is the _____.
central vacuole
The nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles make up the __________.
endomembrane system
Functions of the smooth endoplasmic reticulum include ______.
lipid synthesis, steroid synthesis, and drug detoxification
Based on its function in detoxifying drugs, you would expect to find a large amount of smooth ER in ______ cells.
liver
The Golgi apparatus mainly functions to modify _____.
proteins
