What major type of molecule contributes to the formation of the cell membrane and what biochemical properties of this molecule promotes the formation of the membrane? What effect allows this type of molecule to come together to form a bilayer and explain how the effect works? A▾ B I H 8 2

i need to choose of the following for each one

Choose the best answer 1) If the lipid bilayer in Section B represents the plasma membrane, which part of the protein is the cytoplasmic domain? There is no way to tell which is the cytoplasmic domain with the information given. Section A is the cytoplasmic domain since it contains disulfide bonds. Section C is the cytoplasmic domain since the N-terminus is always found in the cytoplasm. Section C is the cytoplasmic domain since glycosylation cannot occur on the cytoplasmic domain. Section B is the cytoplasmic domain since it is an alpha-helix.  2) Which type of amino acids is most commonly found in Section B? Hydrophilic Hydrophobic There is no way of knowing which type of amino acids is most commonly found in Section B with the given information Charged 3) If the lipid bilayer in Section B represents the ER membrane, which part of the protein is found INSIDE the ER (in the ER lumen)? The entire protein must be inside the lumen of the ER. Section C is inside the ER…

The following table depicts the rate of transport of a molecule into a cell as the external concentrations are changed. Based on what you know about the characteristics of membrane transport, the molecule is most likely transported by: a) passive transport b) simple diffusion across the membrane c) facilitated diffusion d) active transport

What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.

As part of their function, membrane-bound organelles, such as mitochondria and the en- doplasmic reticulum, must move substances across their membranes. Which of the following statements best describes a feature shared by mitochondria and the endoplasmic reticulum that increases the efficiency of their functions? A B с D double membranes, in which one membrane encloses the other rigid and nonfluid membranes membranes composed of carbohydrates highly folded membranes

It seems paradoxical that a lipid bilayer can be fluid yet asymmetrical. Explain.

What makes something hydrophobic/hydrophilic? Which type cannot easily pass through the cell? Why

Which of the following statements are TRUE about the phospholipid bilayer? Select all that apply.         Integral proteins have at least one part touching the inner 'tails' of the membrane.     Peripheral proteins span the entire membrane.     Cholesterol can be used to make the membrane more OR less fluid, depending on the temperature.     Glycolipids and glycoproteins face the inside of the cell.

Which molecule would you predict moves through a lipid bilayer most rapidly without the help of a transport protein? Group of answer choices A NH2SO2CH3 B C6H12O6 C C2H4 D CH3OH E C2H5OH
