Transamination is the process by which amino groups are removed from amino acids and transferred to acceptor keto-acids to generate the amino acid version of the keto-acid and the keto-acid version of the original amino acid. Transamination, a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. Transamination in biochemistry is accomplished by enzymes called transaminases or aminotransferases. Transamination takes place in the cytoplasm.

Abscisic acid (ABA) is a plant hormone that regulates seed dormancy and germination. Seeds undergo changes in both ABA content and sensitivity during seed development and germination in response to internal and external cues. Germination is regulated by a pigment, phytochrome, which is sensitive to different wavelenghts of light. When far red light is receive the phytochrome equilibrium changes towards the red light absorbing form.

A virus is an infectious particle that reproduces by "commandeering" a host cell and using its machinery to make more viruses. A virus is made up of a DNA or RNA genome inside a protein shell called a capsid. Viruses reproduce by infecting their host cells and reprogramming them to become virus-making "factories."

Growth and reproduction cannot be taken as the defining property of all living beings because they are certain living beings in the world which do not show these properties and yet they are living beings. For eg: Drones, Infertile couples cannot reproduce yet they are living. Growth is defined as inversible increase in the number of cells or mass of living structure. If we consider increase in body mass at growth, non living objects like sand mounts grow too. Hence growth cannot be taken as a defining property if living organisms. Though it is a characteristics of living organisms .

The digestion of carbohydrates begins in the mouth. The human saliva contains an enzyme called salivary amylase which digests the starch present in the food into maltose sugar. The slightly digested carbohydrates when reaches the small intestine, pancreatic amylase present in the pancreatic juice breaks down the starch. The intestinal juice of the small intestine completes the digestion of carbohydrates and finally coverts it into glucose.

The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body. Urine is one of the body's waste products. It is primarily composed of water and urea. Urea is a special nitrogenous waste compound that the body must routinely remove. Urine formation occurs in the kidney in three stages: filtration, reabsorption, and secretion. Formation of urine is a process important for the whole organism. Not only acid-base balance is modulated by it, but also blood osmolarity, plasma composition and fluid volume, and thus it influences all cells in our body.
