What is the role of calcium in muscle contraction?
to bind with Troponins changing its shape so the actin filament is exposed
you have designed a drug that is supposed to bind to the myosin sites on actin. You injected into a relaxed muscle, but find that none of the drugs bound. Which of the following best explains why?
The myosin binding sites on acting are covered by tropomyosin
which best describes a myofibril
It is a cylindrical cellular organelle composed of myofilaments.
how is the length of a skeletal muscle sale related to the force it can generate?
skeletal muscle cells generate the most force when the contraction occurs at an intermediate length
what would be the result if the administration of a drug sequesters (inactivates) All the ATP in a cell?
all cross bridges will remain tightly bound to actin.
The major physiological difference between single unit smooth muscle in multiunit smooth muscle is
action potentials can spread from sale to sale in single unit but not in multiunion muscle
which of the following groups of chemicals does not contain hormones
carbohydrates
The specific action of hormones is due to
hormone specific receptors in target sales
when I start in gland extract gland is applied to some sales, these cells respond by starting cell division. However, when a c-AMP inhibitor is first applied to the sale in then the gland extract is applied, The cells do not divide. Therefore the gland extract most likely contains
A peptide hormone
