The key difference between RQ and RER is that RQ is a direct measurement taken from the blood and RER in an indirect measurement taken through the breath. Calorimetry measures the quantity of heat released from metabolism or energy expenditure. Metabolism needs oxygen, and it produces carbon dioxide. Respiratory quotient (RQ) and Respiratory exchange ratio […]
Difference Between Ionotropic and Metabotropic Receptors
The key difference between ionotropic and metabotropic receptors is that ionotropic receptors allow the binding of ionic ligands to them that opens up the ion channel. Meanwhile, metabotropic receptors allow the binding of chemical ligands to the receptors, initiating a cascade of reactions via linking with a G protein. Signal transduction and membrane transport are […]
Difference Between ANP and BNP
The key difference between ANP and BNP is that the main secretion site of ANP is the atria while the main secretion site of BNP is the ventricles. Natriuretic peptides are peptide hormones secreted by the heart, brain and other organs. Atrial and ventricular distension and neurohumoral stimuli stimulate the secretion of natriuretic peptide hormones […]
Difference Between Proteomics and Metabolomics
The key difference between proteomics and metabolomics is that proteomics is the study of all proteins of an organism while metabolomics is the study of all metabolites of an organism. Genomics is the study of the genetic make-up of an organism. Proteomics and metabolomics are two omic sciences related to genomics. Proteome refers to all […]
Difference Between Cellobiose and Cellulose
The key difference between cellobiose and cellulose is that cellobiose is a disaccharide, whereas cellulose is a polysaccharide. Cellobiose and cellulose are carbohydrate compounds. We can categorize carbohydrates into different categories such as monosaccharides, disaccharide and polysaccharides, depending on the structure and the complexity of the carbohydrate. A monosaccharide is a simple sugar, while a […]
Difference Between Porins and Aquaporins
The key difference between porins and aquaporins is that porins are water-filled pores and channels found in the membranes of bacteria and eukaryotes. Meanwhile, aquaporins are membrane proteins that form water-selective channels in living cells. Different molecules go in and out of the cell across the plasma membrane in living organisms. Thus, there are different […]
Difference Between Angiotensin 1 and 2
The key difference between angiotensin 1 and 2 is that angiotensin 1 is produced from angiotensinogen by the action of renin enzyme, while angiotensinogen 2 is produced from angiotensin 1 by the action of angiotensin-converting enzyme. Angiotensin is a peptide which acts on smooth muscle and raises blood pressure. There are three types of angiotensins: […]
Difference Between Choline and Phosphatidylcholine
The key difference between choline and phosphatidylcholine is that choline is a quaternary ammonium compound while phosphatidylcholine is a derivative of choline made up of both choline and phosphoglyceric acid. Choline and phosphatidylcholine are important components in the structure of a eukaryote. Both play an important role in membrane dynamics and membrane physiology of the […]
Difference Between Protein Kinase A and Protein Kinase C
The key difference between protein kinase A and protein kinase C is that protein kinase A is a type of protein kinase that is dependent on cyclic AMP, while protein kinase C is a subfamily of protein kinases that is responsive to lipid signalling. Kinase is an enzyme that catalyzes the transfer of phosphate group […]
Difference Between NCE and NME
The key difference between NCE and NME is that NCE has no active moiety that has ever been approved by the FDA (Food and Drug Administration) whereas NME has an active moiety that has not been approved by the FDA previously. The terms NCE and NME are used to categorize drugs according to the presence […]
