And if there was no convection, the smell would suddenly hit you - not by convection, but by diffusion. Diffusion is the movement of coffee particles from the coffee machine (a high-concentration area) to the rest of the coffee shop (an area of low concentration). The diffusion of coffee...
Uniport Transport Proteins — Only one type of molecule is moved via a transport protein. Movement can be either into or out of the cell/organelle. Symport Transport Proteins — Two types of molecules are moved in the same direction (either both are moved into the cell/organelle or both ar...
So, the smaller the Rf value, the less movement of molecules, the higher the polarity of the molecule is, and the larger the Rf value, the more movement of molecule, the less polar a molecule is. Other Types of Chromatography Beyond thin-layer chromatography, there are several other ...
b) These are generally composed of three to seven carbon atoms per molecule. c) Based on the type of functional group attached to them, monosaccharides are classified into two types i) Aldoses:When the functional group in a monosaccharide is aldehyde \(\left({ – CHO – } \right)\), ...
Detection of a specific molecule occurs on the outer surface of a receptor cell at a plasma membrane protein known as chemoreceptor. Generally, a chemoreceptor will detect just a single chemical or a small range of structurally similar chemicals. Detection elicits a series of biochemical changes ...
4. What are some real-life examples of a fluid? A fluid can be defined as a continuous, amorphous substance molecule that moves freely one after another and tends to acquire the shape of the container in which it is placed. The fluid shows an interesting property through which it resists ...
Water is something that most of us drink daily, and it is otherwise known by the chemical name H2O. For those who are unaware of the meaning, H2O means that each molecule in water contains one hydrogen (H) atom and two oxygen (O) atoms (37). ...
Thick and thin filaments are themselves composed of proteins. Thick filaments are composed of the protein myosin. The tail of a myosin molecule connects with other myosin molecules to form the central region of a thick filament near the M line, whereas the heads align on either side of the ...
Proteoglycans: A protein-sugar molecule found primarily in connective tissue Hyaluronic acid: Promotes the production ofcollagen and elastinproteins, moisturizes the joint, and increases elasticity Other major proteins and enzymes. Enzymes are proteins that help biochemical reactions occur. ...
Simple diffusion is a type of diffusion that does not rely on membrane proteins for transport. In general, the particle or molecule travels from a greater concentration to a lower concentration. However, the movement of particles does not necessitate the presence of a membrane protein that aids ...
