COL1A1 and COL1A2 are two genes that, respectively, encode the two α1 chains and a single α2 chain in the Type I collagen. Type I collagen is a fibrillar collagen and the most abundant type in the body. It is a heterotrimer and is the key structural protein in several tissues. The key difference between […]
What is the Difference Between HLA-A and HLA-B
HLA-A and HLA-B are two major histocompatibility complex antigens specific to humans. They perform an important immune function by presenting small peptides to the immune system. Human leukocyte antigens are cell-surface proteins. They were discovered in the 1930s by Peter Gorer. Human leukocyte antigens are encoded by specific genes clustered within the major histocompatibility complex (MHC) at Chromosome […]
What is the Difference Between ACE1 and ACE2
ACE1 and ACE2 are two important enzymes involved in the renin-angiotensin-aldosterone system (RAAS). ACE2 enzyme plays an important function in this system. It acts as a counterbalance to ACE 1. ACE1 cleaves the angiotensin I hormone into the vasoconstricting angiotensin II, which leads to an increase in the body’s blood pressure. ACE2 has an opposing effect to […]
What is the Difference Between Adrenaline and Cortisol
Adrenaline and cortisol are two hormones produced by the adrenaline glands. The adrenal glands, also known as suprarenal glands, are important endocrine glands in the human body. They are located above the kidneys. The adrenal cortex typically produces three main types of steroid hormones: mineralocorticoids, glucocorticoids (such as cortisol), and androgens. The adrenal medulla produces […]
What is the Difference Between Cyclic and Noncyclic Electron Flow
Cyclic and noncyclic electron flow are two types of electron flows in photosynthesis phosphorylation. Photophosphorylation is the process of using light energy from photosynthesis in order to convert ADP to ATP or for ATP production. This process synthesizes energy-rich ATP molecules by transferring the phosphate group into the ADP molecule when light is present. The […]
What is the Difference Between EtCO2 and PaCO2
EtCO2 and PaCO2 are two important measurements in capnography. Capnography involves monitoring the concentration or partial pressure of carbon dioxide (CO2) in respiratory gases. It is a monitoring tool used during anesthesia and intensive care. PaCO2-ETCO2 gradient is the difference between arterial and end-tidal carbon dioxide in capnography, which is normally 0.5 kPa (3.8 mmHg). This value can be […]
What is the Difference Between Hybrid and GM Seeds
Hybrid and GM seeds are two types of seeds created by biotechnology. Plant breeding is the process of developing new plant varieties. There are different types of breeding techniques such as inbreeding, backcrossing, hybridization, genetic engineering, and mass selection. Nowadays, hybrid and GM seeds are common in the agriculture industry. Both these seeds are better […]
What is the Difference Between Urine and Filtrate
Both urine and filtrate are products of the urine creation. Kidneys filter unwanted substances from the blood in order to produce urine and excrete it. There are three main steps in the urine creation: glomerular filtration, reabsorption, and secretion. The key difference between urine and filtrate is that urine is the nitrogenous liquid that contains filtering wastes […]
What is the Difference Between Oxyhemoglobin and Carboxyhemoglobin
Oxyhemoglobin and carboxyhemoglobin are two different forms of hemoglobins. Hemoglobin is the protein in red blood cells responsible for the delivery of oxygen to the tissues. It contains iron, and almost all vertebrates have hemoglobin except for the fish family known as Channichthyidae. The key difference between oxyhemoglobin and carboxyhemoglobin is their composition. Oxyhemoglobin is a compound […]
What is the Difference Between Internal and External Intercostal Muscles
Internal and external intercostal muscles are two different types of intercostal muscles. Intercostal muscles run between the ribs. They help form and move the chest wall. Most importantly, intercostal muscles help in breathing. They help to expand and shrink the size of the chest cavity during the breathing process. The key difference between internal and external intercostal […]
