What is the molecule that amino acids and proteins all have and carbohydrate and lipid lack? Biomolecules: There are four classes of macromolecules, or large molecules, that have important roles in the lives of living organisms. These are nucleic acids (DNA and RNA),...
What is the hydrophobic part of the cell membrane? How are molecules transported across a cell membrane? Which type of molecule will require some amount of energy to cross the cell membrane? The lipid bilayer molecules do what for the cell? What is bulk transport cell membrane? Which mac...
that self-assembly has previously involved identical copies of the same molecule--molecule A connects to another molecule A. New work proves not only that alternating peptides can create these beta sheets--in an ABAB pattern--but why it happens.This image is an adaptation of ...
s present in two forms unesterfied and esterfied. The picture below shows a diagram of what a cholesterol molecule looks like in it’s unesterfied form. When it is esterfied, there is an attachment on the molecule which makes it larger. Knowing that there is a size difference in these...
Nonpolar Molecules Nonpolar molecules are hydrophobic; "hydro-" means water and "-phobic" means fear. Nonpolar molecule are water fearing and do not easily dissolve in water. These molecules have nonpolar covalent bonds or polar covalent bonds, both of which share their electrons equally between th...
What is the hydrophobic molecule? A type of lipid that is produced by nearly every tissue in the body and that acts as a local regulator of metabolism are the ___. (a) prostaglandin (b) steroids (c) monoglycerides (d) phospholipids (e) glycolipids. Nutrient:...
Fill in the blank: "A__is composed of two or more atoms held together by chemical bonds." There is more than one answer, but the one that probably crossed your mind first is "molecule." Every grouping of two or more atoms is amolecule. Some are very simple, such as the oxygen mol...
molecule is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. No matter what shape a bubble has initially, it will try to become a sphere. The sphere is the shape that minimizes the surface area of ...

This process is enabled by a "docking" site on the small ribosomal subunit. Here, both a methionyl-tRNA (the specialized RNA molecule transporting methionine) and the mRNA bind to the ribosome, coming closer to each other and allowing the mRNA to direct the right tRNA molecules (there are ...
