Aerobic respiration refers to the concept of the breakdown of nutrients and the production of energy. Any organism, when consuming any nutritive material, the material goes through a series of biochemical reactions by which simple form of carbohydrates, proteins, and lipids are produced. After that, these produced compounds are further degraded and …
What is Hepatitis A Virus? Hepatitis A virus (HAV) is a cause of acute liver inflammation or hepatitis. It can cause relapsing signs and symptoms but not a chronic infection. The virus is a 27-nm-diameter non-enveloped RNA virus. It belongs to the family Picornaviridae and the genus Hepatovirus. Viral transmission occurs in a …

Eicosanoids definition Eicosanoids are biologically active lipid derivatives of unsaturated fatty acids containing 20 carbons. Eicosanoids are locally acting bioactive hormones that act near the point of hormone synthesis and included in the class of paracrine hormones. disease. Eicosanoids are derived from arachidonic acid and related polyunsaturated fatty acids (PUFAs) such as …

Diabetes is a set of condition that occurs due to disruptions in metabolism which is described by high blood sugar level that results from the deficiency of secretion of insulin, action of insulin, or both of the phenomenon is called diabetes [1]. Here in this, I will be discussing diabetes and its …
Cholesterol levels in the body originate from its biosynthesis and diet. Most of the cholesterol used by active adults is produced in the liver, which produces ~70% of daily cholesterol demand (~1 gram). The other 30% originates from dietary absorption. Biosynthesis of cholesterol commonly happens in the endoplasmic reticulum of hepatic cells. …
Gluconeogenesis definition Gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors. Gluconeogenesis is a universal pathway found in all animals, plants, fungi, and microorganisms. Site of gluconeogenesis In higher animals, gluconeogenesis occurs in the liver and to a lesser extent in the kidney cortex. Eventually, under normal circumstances, the liver is responsible …
Pancreas The pancreas is a glandular organ in the upper mid-region, however, it fills in as two organs in one: a stomach related exocrine organ and a hormone-delivering endocrine organ. Working as an exocrine organ, the pancreas discharges catalysts to separate the proteins, lipids, sugars, and nucleic acids in nourishment. Working as …

Image Source: BioNinja Classes of Plant Hormones Major classes of hormones produced by plants and PGPR are: Auxins (IAA) Cytokinins Gibberellins (GA) …
Amino acids Proteins are the structural scaffolds of our bodies. At the molecular level whatever function is going on, it is being assisted or done by a protein. Proteins have a wide array of structures and functions, but all proteins are similar when it comes to their building blocks. These are the …
