Ca+ binds to troponin -> Troponin removes tropomyosin from G actin -> Myosin binds to actin -> Myosin generates a power stroke -> the sarcomere shortens -> ATP recharges the myosin head
very few M. tuberculosis in the standard nutrient cell cultures carry the rpoB gene mutation, but almost all of the M. tuberculosis in the cell cultures with rifampin carry the rpoB mutation
Simple carbohydrates contain just one or two sugars, such as fructose (found in fruits) and galactose (found in milk products). These single sugars are called monosaccharides.
