Review on iron and its importance for human health

Biochemistry and physiology. In contrast to zinc, iron is an abundant element on earth[2,9] and is a biologically essential component of every living organism.[10,11] However, despite its geologic abundance, iron is often a growth limiting factor in the environment.[] This apparent paradox is due to the fact that in contact with oxygen iron forms oxides, which …

Respiration in Plants

Plants undergo cellular respiration in three stages. Glycolysis is the first stage of cellular respiration, which takes place inside the cytoplasm and produces energy under anaerobic conditions.Kreb's cycle is the second stage of aerobic respiration, which occurs inside the mitochondrial matrix..
