What Is Apoenzyme? Apoenzyme is the protein component in which together with cofactor forms a complete enzyme. In other words, an enzyme that requires a cofactor but does not have one bound. An Apoenzyme is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor. Enzymes can speed up … Read more

What Is Waveguide? A wave guide is a specialized structure that guides waves such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. It is designed to channel and manipulate electromagnetic energy along a specific path while minimizing losses and radiation. Waveguides are hollow metal … Read more

What Is Epigeal?  Epigeal germination is a type of germination whereby the seed leaves or the cotyledons are brought on to the surface or above the soil along with the shoot during germination. This is usually due to rapid elongation and curved-like shape of the hypocotyl. This change in the shape or curvature of the … Read more

Virtual Circuits Virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. Before the data transfer begins, the source and destination identify a suitable … Read more

Enzymes Enzymes are biological molecules typically proteins that speed significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve as a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large … Read more

Joint Photographic Experts Group (JPEG) JPEG is an acronym for ‘’ Joint Photographic Experts Group”. It’s a standard image format for containing lossy and compressed image data. Despite the huge reduction in file size JPEG images maintain reasonable image quality. This unique compression feature allows JPEG files to be used widely on the internet, computers … Read more

What Is SN1 Reaction? The SN1 reaction is a substitution reaction in organic chemistry. ‘’SN’’ stand for ‘’nucleophilic substitution’’ and ‘’1’’ says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of … Read more

DNA is a two-stranded molecule. One strand of DNA holds the information that codes for various genes, this often referred to as the template strand or antisense strand (containing anticodons). The other complementary strand is referred to as the coding strand or sense strand (containing codons). What Is Template Strand? Transcription is the process in … Read more

What Is Diffusion? Diffusion is a physical process that refers to spontaneous movement of particles from a region of high concentration to a region of low concentration. Concentration refers to how much a particular object or particle is in a given space. Gasses and molecules in a liquid have a tendency to diffuse from a … Read more

What Is Cofactor? A cofactor is a non-protein chemical compound that is required for the protein’s biological activity. Many enzymes require cofactors to function properly. Cofactors can be considered “helper molecules’’ that assist enzymes in their action. Many cofactors will sit in the enzyme site and assist the biding of the substrate. An inactive enzyme … Read more
