Which process moves water molecules across the membrane of a cell? What kind of cells make up the basement membrane? What is a membrane-bound network that processes proteins and lipids called? What are the major component of cell membranes? Which molecule allows the transport of charged s...
If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Polyatomic moleculeshave more than two atoms, such as water (H2O) and carbon dioxide (CO2). Larger molecules are calledpolymersand may be made of thousands of atoms...
A molecule, such as H20, is the smallest unit of a compound that maintains the characteristics of that compound. A compound often looks and behaves differently from its constituent elements. Consider a water (H2O)molecule, which is made up of two hydrogen atoms and one oxygen atom. Both hydr...
Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the molecule that contains all of the information required to build and maintain the cell; RNA ha...
A water molecule is composed of two elements: one oxygen atom and two hydrogen atoms. Water is a polar molecule, meaning the electrons are not shared equally between the three atoms. Oxygen has a high electronegativity, or electron-loving, making the oxygen end of a water molecule slightly ne...
Sucrose is a disaccharide. This is a molecule made of two simple sugars—glucose and fructose—in a 1:1 ratio and chemically bound. Sucrose is used in many processed foods. High fructose corn syrup, also used in processed foods, is a mixture of the monosaccharides glucose and fructose. Usua...
The analysis of cellular ultrastructure is paramount for gaining a comprehensive understanding of cell functionality. By examining the intricate details within a cell, researchers can uncover the mechanisms that drive various cellular processes and functions. ...
