Receptor is a specialized modified sensory nerve ending which undergoes depolarization in response to a specific stimulus and in turn sends information to the CNS. It’s function is to act as a transducer to convert various forms of energy into electric energy in Neuron. Each type of sensation (pain, touch, vibration etc) is called modality …

What is the GFR? It is the ultra-filtration of plasma in the glomerulus. The glomerular filtration rate is the amount of blood filtered by the kidney’s glomerulus into the bowman’s capsule per unit of time. It is abbreviated as GFR. Its normal value is 125ml/min or 180L/24 hours. The rate of filtration is influenced by …
TRANSAMINATION What is transamination? The transfer of an amino group from an amino acid to a keto acid is known as transamination. It is catalysed by a group of enzymes called transaminases (recently aminotransferases) What is the mechanism of transamination? Occurs in two stages Transfer of the amino group to the coenzyme pyridoxal phosphate (PLP) …
Features: Endocrine gland Consists of right and left lobe connected by an isthmus Functions: Regulates basal metabolic rate Stimulates psychic and somatic growth Regulates calcium metabolism. Being one of the important glands in our body, we have to know everything about this gland in detail. We are going to cover the following: Situation and Extent …
The process of synthesizing ATP from ADP & Pi coupled with electron transport chain is known as oxidative phosphorylation. For this oxidation to take place, many components are required. One of them is NADH, the reducing equivalent. Transport of reducing Equivalents – the shuttle pathways. The inner mitochondrial membrane is impermeable to …
