The key difference between positive and negative oxidase test is that positive oxidase test indicates the presence of cytochrome C oxidase in bacterium, whereas negative oxidase test indicates the absence of cytochrome C oxidase. The term oxidase test is usually useful in microbiology and has applications in analytical chemistry as well. An oxidase test detects […]
Difference Between STAT5A and STAT5B
The key difference between STAT5A and STAT5B is that STAT5A is a protein in humans coded by STAT5A gene while STAT5B is a protein in humans coded by STAT5B gene. Signal transducer and activator of transcription (STAT) is a family of universal transcription factors. They are proteins that help cells to sense and respond to […]
Difference Between Benzodiazepines and Barbiturates
The key difference between benzodiazepines and barbiturates is that barbiturates cause a high neuronal depression when compared to benzodiazepines. Benzodiazepines and barbiturates are drugs that are useful in medicine. Benzodiazepines have the structure of a benzene ring that is fused with a diazepine ring while barbiturates are chemical derivatives of barbituric acid. CONTENTS 1. Overview and […]
Difference Between E and N Cadherin
The key difference between E and N cadherin is that E cadherin is downregulated during Epithelial-to-Mesenchymal Transition (EMT) in cancers while N cadherin is upregulated during EMT in cancers. Cadherin is a molecule that is important in the formation of adherens junctions when binding cells with each other. Therefore, they are cell adhesion molecules which are transmembrane […]
Difference Between Ion Channel and Ion Pump
The key difference between ion channel and ion pump is that ions move passively through ion channels while ions move actively through ion pumps. Ions travel across the plasma membrane through ion channels or ion pumps. Ion channels are transmembrane proteins that passively transport ions down their electrochemical gradient across the cell membranes. Ion pumps […]
Difference Between Cis and Trans Fat
The key difference between cis and trans fat is that in cis fats, the two H atoms are present on the same side of the double bond while in trans fats, two H atoms are present on the opposite sides of the double bond. Fats or fatty acids are carboxylic acids comprised of a straight chain […]
Difference Between Direct and Indirect Hormone Action
The key difference between direct and indirect hormone action is that direct hormone action occurs when hormones directly act on non-endocrine tissues while indirect hormone action occurs when hormones modulate the secretory activity of other glands. Hormones are chemical messenger secreted into the bloodstream. They can be amino acid derivatives, peptide hormones or lipid derivatives. […]
Difference Between Steroid and Corticosteroid
The key difference between steroid and corticosteroid is that steroids are components in biological systems and can alter the membrane fluidity in cell membranes and act as a signalling molecule, whereas corticosteroids are a type of steroid hormones. Steroids are biological components that are important in cell regulation processes. Corticosteroids are a type of steroids; […]
Difference Between Ribitol and Glycerol Teichoic Acid
The key difference between ribitol and glycerol teichoic acid is that ribitol teichoic acid contains polyribitol phosphate units in the main chain, while glycerol teichoic acid contains poly-glycerol phosphate units in the main chain. Teichoic acid is a compound found in the cell wall of most Gram-positive bacteria. Teichoic acids are copolymers of glycerol phosphate […]
Difference Between Parallel and Antiparallel Beta Pleated Sheets
The key difference between parallel and antiparallel beta pleated sheets is that in parallel beta pleated sheets, polypeptide strands run in the same direction, while in antiparallel beta pleated sheets, neighbouring strands run in opposite directions. Beta pleated sheet or beta sheet is a common secondary structure of proteins. There are hydrogen bonds between beta […]
