Glycolysis

Glycolysis is the first phase of a series of reactions for the catabolism of carbohydrates. Catabolism is the breakdown of larger molecules into its respective smaller constituents. Glycolysis is the first part of cellular respiration that generates pyruvate to be used in either anaerobic respiration in the absence of oxygen or in the TCA cycle … Continue reading Glycolysis

Lactate Dehydrogenase

Lactate dehydrogenase (LD, LDH) is an enzyme that is found in all cells in all tissues of the body. It catalyzes the reversible conversion of lactate to pyruvic acid in glycolysis and gluconeogenesis. It is released from various anatomical sites of the body in response to cellular injury and damage. It is used as a … Continue reading Lactate Dehydrogenase

Hemoglobin, What is it?

Function Hemoglobins main function is to carry oxygen to the tissues and cells of the body. Hemoglobin can bind and transport four molecules of oxygen. Hemoglobin is made up of 4 polypeptide globin chains, two alpha and two beta that forms a tetramer heme group with iron located within the tetramer. Globin is the protein … Continue reading Hemoglobin, What is it?
