- QIV. Determine if the level of organization is molecular or cellular. Tick True if molecular. Tick False if cellular. Prokaryotic cells have no membrane-bound nucleus, and the organelles have no surrounding membranes. Select one: O True O FalseNote that the number of transport proteins (pores) on a cell and their size can help the cell to control which kinds of molecules are inside and in what quantities. Link to the website: Next-Generation Molecular Workbench (concord.org)A. Choose your favorite organelle. Make a detailed 2-D hand-drawing of the organelle. Writea brief description of its structure. Discuss its significance for sustaining the life of the cell(max. 3 sentences).B. In relation to the formation of cells and evolution of life, perform a little investigation onsome theories on how cells are formed and organelle origins. Draw by hand images toillustrate and support the theories that formed your favorite organelle.
- The figure below illustrates a portion of a cell membrane. X denotes a membrane-spanning protein channel. Illustration of a partial cell membrane Which of the following is most likely true about the structure of X X A The upper and lower ends of X are hydrophilic and its middle is hydrophobic. C D The upper and lower ends of X, as well as its middle, are all hydrophobic. The upper and lower ends of X are hydrophobic and its middle is hydrophilic. The upper and lower ends of X, as well as its middle, are all hydrophilic.Draw out protein transport in the cell. Make sure to include all steps involved in transport through the secretory and endocytic pathways (including ER resident protein retrieval, transport to lysosome), transport in and out of the nucleus, and import into mitochondria. Include all details of vesicle transport (protein coat, SNARES, Rab) in your drawingPhospholipids. Response to a signal includes: Gene expression O Metabolic activity O Membrane permeability modification O All of the above Most enzymes are:
- A cell is like our school. Each part of the cell (and school) has responsibilities thatmust be done and certain organelles (people or places) do them. Identify the function of the following parts of the cell. Then, identify which person does the same job (or a place like it) in the school. The first one is done for you as an example to follow. (Picture attached below).Choose a particular type of protein as an example. Show your cell model making that protein. Show the following organelles and describe their role in making, modifying, or transporting the protein: Nucleus Ribosomes Rough ER Vesicles Golgi apparatus Where the protein goes and what it does when it's finished.esc Decide whether each molecule in the table below could be found embedded in the outer surface of a cell membrane. For each molecule that could, decide whether the outside of the cell would lie to the right or left of the molecule as drawn. Note for advanced students: none of these molecules are actually found in cell membranes. Your goal is to use the principles of biochemistry to decide whether they could be, if for example they were synthesized and studied as drug candidates. HO.

- You are studying a protein that ends up outside the cell. If you fractionated cellular organelles, in which fraction would the protein be found? А. nuclear В. cytoplasmic ER plasma membraneImage analysis. The outer boundary of the cell is the plasma membrane.In the image below, molecules that cannot cross the membrane are glucose and ions.Why can't they cross the membrane? [MA] (c) (d) (a) Small uncharged molecules (b) Lipid-soluble Water-soluble substances lons substances Glucose Hydrocarbon Nat K+ H20 CO2 H+ cF Cat+ NH3 O They are hydrophobic O They are hydrophilic O large O Na, K, Ca and H ions will bind with phosphate Chloride ions will be repelled by phosphate they are small in size toplease choose correct letter and explain a bit 1. The strongest way by which a protein can maintain its shape is by using:a) ionic bonds b) disulfide bonds c) star war forces d) van der Waals forces 2. If a cell (like an amoeba) would be capable of migrating from one place to another only with movement created from the inside of the cell, then we can say that that movement is done mainly by: a) glycoproteins b) feet c) microtubules d) actin filaments True or False: In eukaryotic cells (such as human cells), the variety and diversity of proteins is much less than the variety and diversity of lipids.
