Question
Which type of organelle is primarily involved in the synthesis of oils, Phospholipids, and steroids? ribosomes lysosomes smooth endoplasmic reticulum mitochondria contractile vacuoles Which of the following types of molecules are the major structural components of the cell membrane lipid bilayer? phospholipids, sphingolipids. and cholesterol nucleic acids, phosphoglycerides, and proteins phospholipids, cholesterol and proteins proteins, sphingolipids, and cellulose glycoproteins, phosphoglycerides, and cholesterol What is one of the ways that the membranes of winter wheat are able to remain fluid when it b extremely cold? by increasing the percentage of unsaturated phospholipids in the membrane by increasing the percentage of cholesterol molecules in the membrane by decreasing the number of hydrophobic proteins in the membrane A and B A.B, and C. Membrane phospholipids are considered because they have hydrophobic tails only have hydrophilic heads only have hydrophobic tails and hydrophilic heads have hypertonic proteins have hypotonic lipids Which of the following statements best describes a typical membrane? it may have different kinds of lipids the lipid molecules in the membrane are attached to each other all lipids and proteins in the membranes are equally mobile it contains a hydrophilic core Most of the carbohydrates found on plasma membranes are located on the cytosolic face the exoplasmic face a and b none of the aboveExplanation / Answer
