Lineweaver–Burk Plot with Example

Lineweaver–Burk Plot

Lineweaver–Burk Plot The Lineweaver–Burk plot (also known as the double reciprocal plot) is a graphical representation of enzyme kinetics used to determine the Michaelis-Menten parameters VmaxVmax​ (maximum reaction velocity) and KmKm​ (Michaelis constant). Because Vmax is attained at endless substrate concentration, estimating Vmax and thus Km from a hyperbolic plot is impossible. Due to this issue, Lineweaver and Burk modified the Michaelis–Menten equation … Read more

Cell Wall: Definition, Diagram, Structure And Functions

Cell Wall: Definition, Diagram, Structure And Functions

Cell Wall Definition Around the inner plasma membrane, an outermost layer provides protection and strength to the cell. This outermost layer is the cell wall. Protoplast, a living structure, forms the non-living cell wall.  The cell wall is not a characteristic of all types of cells. Some cells show their presence like plant cells, fungi, … Read more

Phylum Porifera: Classification, Characteristics, Examples

Phylum Porifera: Classification, Characteristics, Examples

Definition of Porifera Porifera are asymmetrical or radially symmetrical multicellular organisms with a cellular grade of organisation lacking well-defined tissues as well as organs; exclusively aquatic; mostly marine, sedentary, solitary or conical animals with a body perforated by pores, canals, as well as cambers through which water flows; with one or more internal cavities lined … Read more

Dissecting Microscope (Stereo Microscope) Definition, Principle, Uses, Parts

Dissecting Microscope Parts (Stereo microscope)

Dissecting Microscope (Stereo Microscope) Dissecting Microscope or Stereoscopic microscopes are another name for these. Dissection microscope is a digital optical microscope having low magnification power (5x-250x) which uses light reflected from the specimen’s surface instead of light reflected from the specimen itself. Its principal function is to dissect specimens as well as observe as well … Read more

Epithelial Tissue Vs Connective Tissue: Definition, 16+ Differences, Examples

Epithelial Tissue Vs Connective Tissue: Definition, 16+ Differences, Examples

Definition of Epithelial Tissue Epithelial tissue is a kind of animal tissue which is composed of highly aggregated polyhedral cells which are tightly attached to each other as cellular sheets which line the inside of hollow organs and cover the body surface. Cells in epithelial tissue or epithelium (plural: epithelium) are organized in continuous sheets, in … Read more

29+ Differences Between Arteries and Veins

Differences Between Arteries and Veins

 Arteries and Veins Arteries and veins are two of the most common types of blood vessels in the body, through which blood flows. The arteries transport oxygenated blood out from the heart, whereas the veins transport deoxygenated blood from the tissue capillaries back to the heart. Differences between Arteries and Veins  Arteries Vs Veins   … Read more

Eukaryotic Cells: Definition, Parts, Structure, Examples

Eukaryotic Cells: Definition, Parts, Structure, Examples

Definition of Eukaryotic Cells Eukaryotic cells feature a membrane-bound, well-defined nucleus as well as several membrane-bound organelles, making them complicated in structure as well as function. The term “eukaryote” comes from the Greek words “eu” as well as “karyon,” which mean “true” as well as “nucleus,” respectively. When compared to prokaryotes, eukaryotic cells have a … Read more
