endomembrane +

Biology exam 2-chapter 7 endomembrane system and more

QuestionAnswer
What organelles in the cell are included in the endomembrane system? Nuclear envelope, endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, endosomes, plasma membrane
What is the function of nuclear envelope? Protects the cell's genetic material, compartmentalizes the nucleus, and regulates the exchange of substances between the nucleus and cytoplasm.
What is the function of endoplasmic reticulum (ER)? Synthesizes, processes, and transports proteins and lipids within the cell.
What is the function of Golgi apparatus? Processes, modifies, and packages proteins and lipids for transport within the cell or secretion outside the cell.
What is the function of lysosomes? Break down macromolecules, old cell parts, and microorganisms using digestive enzymes.
What is the function of vesicles? Transport materials within the cell and facilitate the movement of substances between organelles and the cell membrane.
What is the function of endosomes? Sort and direct vesicular traffic, ensuring that materials are delivered to their correct destinations within the cell.
What is the function of plasma membrane? Regulates the entry and exit of substances, maintaining the cell's internal environment and facilitating communication with its surroundings.
How are the organelles in the cell related to each other? Interconnected through the endomembrane system and vesicular transport, working together to ensure efficient cellular function and communication.
What is the structure of the endoplasmic reticulum (ER)? Network of membranous sheets and tubules that extends from the nuclear envelope throughout the cell
What are the various functions of the ER? Involved in protein synthesis and folding, lipid synthesis, calcium storage, and detoxification of drugs and poisons
What are the two types of ER? Rough ER and Smooth ER
What is rough ER? Studded with ribosomes and involved in protein synthesis
What is smooth ER? Lacks ribosomes and is involved in lipid synthesis and detoxification process
What is Golgi apparatus? Modifies, sorts, and packages proteins and lipids for transport within the cell or secretion outside the cell.
What is the structure of the Golgi apparatus? A series of flattened, stacked pouches called cisternae that modify, sort, and package proteins and lipids for transport within the cell or secretion outside the cell.
What is the directionality of the Golgi apparatus? Cis face and trans face
What is the function of the Golgi apparatus? Modifies, sorts, and packages proteins and lipids for transport within the cell or secretion outside the cell.
What are the types of molecules in the Golgi apparatus? Proteins, lipids, and polysaccharides
how do the molecules move through the Golgi apparatus? They move by vesicular that transport them via cis face and trans face
what happens to these molecules as they move through the various parts of the Golgi apparatus? They are sequentially modified, sorted, and packaged for their specific destinations within or outside the cell.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
