Organelles Working Together 0.0 / 5 ? BiologyCellular processesASOCR Created by: lauren.glendenningCreated on: 22-04-16 20:39 What type of production are organelles involved in? Protein production 1 of 18 Where are proteins made? The ribosomes 2 of 18 What happens to the proteins that are made by ribosomes on the rough endoplasmic reticulum make? They are excreted or attached to the cell membrane 3 of 18 What happens to the proteins made by free ribosomes? They stay inside the cytoplasm 4 of 18 What happens to new proteins at the rough endoplasmic reticulum? They are folded and processed (sugar chains are added) 5 of 18 Where do the proteins go once they have left the rough endoplasmic reticulum? To the golgi apparatus in vesicles. 6 of 18 What happens to the proteins at the golgi apparatus? They are further processed (sugar chains are trimmed or new ones are added) 7 of 18 What happens to the proteins once they have left the golgi apparatus? They enter more vesicles and are transported around the cell 8 of 18 Give an example of a protein function once it leaves the golgi apparatus? Glycoproteins are found in mucus move to the cell surface and are secreted. 9 of 18 What are organelles surrounded by? Cytoplasm 10 of 18 What type of network does the cytoplasm have? A network of protein threads running through it 11 of 18 What are the protein threads in the cytoplasm known as? The cytoskeleton 12 of 18 How are the protein threads arranged in eukaryotic cells? As microfilaments (small solid strands) and microtubules (tiny protein cylinders) 13 of 18 What are the four main functions of the cytoskeleton? Keeping the cell's organelles in position, strengthening and maintaining the shape of the cell, transport of materials within the cell, cell movement. 14 of 18 How does the cytoskeleton keep the cell's organelles in position? The microtubules and microfilaments support the organelles keeping them in position. 15 of 18 What strengthens the cell and helps it to maintain it's shape? The microfilaments and microtubules 16 of 18 Give an example of how the cytoskeleton is responsible for the transport of materials within the cell? The movement of chromosomes when they separate during cell division depends on contraction of microtubules in the spindle. 17 of 18 Give an example of how the cytoskeleton can cause the cell to move. The movement of cilia or flagella is caused by the cytoskeleton protein filaments that run through them. 18 of 18
