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.
Plantain sends up a leafless flower stock in summer/fall - the stalks can be up to ten inches tall. There are over 200 species in the plantain family, and they are found worldwide. Many have herbal uses. Plantago major is the most common one in North America, but Plantago lanceolata can also be found. Both have the same medicinal uses, and are very similar in appearance.
