Myosin heads attach to actin by breaking down ATP to ADP and a phosphate via Myosin-ATPase The Myosin head forms a âcross-bridgeâ on the active site of the actin filament. The cross bridge pulls actin, which slides over the myosin â known as the âPower Stroke.â
Plantain (or Plantago Major) is a common backyard herb with broad leafs. Most people think of it as a weed, though it is an incredibly useful herb. According to Mountain Rose Herbs: âLegend has it that Alexander the Great discovered it and brought it with him back to Europe in 327 BCE.
The sub-species, sapientum, formerly regarded as a distinct species (M. sapientum), is the source of the fruits generally known in England as Bananas and eaten raw, while the name Plantain is given to forms of the species itself which require cooking. The species is probably a native of India and Southern Asia. Other species are M. acuminata in the Malay Archipelago, M. Fehi, in Tahiti, and M. Cavendishii, the so-called Chinese Banana, which has a thinner rind and is found in cooler countries.
