The key difference between lyases and transferases is their primary function. Lyases are enzymes that catalyze the dissociation or breakdown of molecules by cleaving the bonds between them. Meanwhile, transferases are enzymes that catalyze the transferring of a functional group from one molecule to another molecule. Enzymes are biocatalysts of biochemical reactions. They are proteins, […]
Difference Between Enzyme Inhibitor and Enzyme Inducer
The key difference between enzyme inhibitor and enzyme inducer is that enzyme inhibitor decreases the activity of an enzyme by binding with the active site of the enzyme. In contrast, enzyme inducer increases the metabolic activity of an enzyme either by binding to it or by increasing the gene expression. Enzymes are the biomolecules that […]
Difference Between Cytochrome and Phytochrome
The key difference between cytochrome and phytochrome is that cytochrome is an electron transfer heme protein involved in aerobic respiration. Meanwhile, phytochrome is a photoreceptor protein that is sensitive to red and far-red light of the visible spectrum. Living organisms have different types of pigments. Some are light-absorbing pigments while some are respiratory pigments. Cytochrome […]
Difference Between Hemocyanin and Hemoglobin
The key difference between hemocyanin and hemoglobin is that hemocyanin is a copper-containing extracellular respiratory pigment present in some invertebrate blood while haemoglobin is an iron-containing intracellular respiratory pigment present in vertebrate blood. In aerobic organisms, gas exchange occurs through the metalloproteins present in the blood. Therefore, hemocyanin and hemoglobin are two metalloproteins that facilitate […]
Difference Between Somatostatin and Somatotropin
The key difference between somatostatin and somatotropin is that somatostatin is a growth hormone-inhibiting hormone that works as a somatotropin release inhibiting factor. Meanwhile, somatotropin is a growth hormone that stimulates the growth of essentially all tissues of the body. Hormones are chemical signalling molecules that carry messages between different parts of the body. They […]
Difference Between Ferritin and Transferrin
The key difference between ferritin and transferrin is that ferritin is a protein that stores iron in the blood whereas transferrin is a protein that can combine with ferritin and move to sites where new blood cells are formed. Ferritin and transferrin are proteins that are important in storing and transporting iron in the blood. […]
Difference Between AMPA and NMDA Receptors
The key difference between AMPA and NMDA receptors is that the specific agonist of AMPA receptor is alpha-amino – 3 – hydroxyl – 5 – methyl – 4 – isoxazole propionic acid (AMPA), while the specific agonist of the NMDA receptor is N – methyl – D – aspartate (NMDA). There are three main types […]
Difference Between Retinyl Palmitate and Retinol
The key difference between retinyl palmitate and retinol is that retinyl palmitate is a form of vitamin A; it is an ester formed from the reaction of retinol and palmitic acid. Meawhile, retinol is the purest form of vitamin A. Vitamin A is a fat-soluble nutrient. It is an organic compound that contains retinol, retinoic […]
Difference Between Blood Urea Nitrogen and Blood Urea
The key difference between blood urea nitrogen and blood urea is that blood urea nitrogen measures the amount of nitrogen in urea that is present in the blood, while blood urea is the measurement that deduces the total amount of urea in the blood. During protein metabolism, degradation and removal of remnants of protein metabolism, […]
Difference Between Cutaneous and Pulmonary Respiration
The key difference between cutaneous and pulmonary respiration is that cutaneous respiration takes place through the skin, while pulmonary respiration takes place through the lungs. There are two types of respiration as internal respiration and external respiration. Internal respiration refers to cellular respiration that produces energy or ATP. External respiration refers to pulmonary respiration or […]
