During the crossbridge cycle of skeletal muscle contraction, the binding of adenosine triphosphate (ATP) to the globular myosin head first causes which of the following? Select one: a. Movement of tropomyosin to expose the myosin binding site on the actin molecule b. Myosin head to bind to actin c. Myosin head to detach from actin d. Myosin head to swing forward pulling actin toward the M-line e. Myosin head to be cocked into its high-energy state

The reaction is glucose with adenosine triphosphate (ATP) to form glucose 6- phosphate and adenosine diphosphate (ADP). This reaction has a calculated equilibrium constant (K) of 1.90 × 105. What are the equilibrium concentrations of glucose and ATP if the initial concentrations of both are 0.100 M?

You are investigating the effects of ATP, Ca2+, and other ions on skeletal muscle contraction, and are conducting two experiments. First using glycerinated muscle, you can compare the ability of muscle to contract under 3 experimental conditions (1: ATP; 2: KCl+MgCl2; and 3: ATP+KCl+MgCl2). Second, using fresh muscle, you compare the ability of muscle to contract under another 3 experimental conditions (1: ATP; 2: Ca2+; and 3: ATP+Ca2+). For each experiment, what results would you expect regarding the amounts of...

During the excitation phase of the skeletal muscle cell contraction, the following occurs: 1) the muscle fiber develops tension and shortens 2) the muscle fiber relaxes and returns to its original length 3) nerve action potentials lead to muscle action potentials A growing long bone in a child has only two types of cartilage at the epiphysis. These two areas are 1) elastic cartilage and epiphyseal plate 2) epiphyseal plate and epiphyseal line 3) primary and secondary ossification centers 4)...

During static muscle activity, there is a strong compressive effect from skeletal muscle contraction coupled with an absence of rhythmic muscle activity. Describe how this would change arterial pressure (afterload) and venous return (preload) compared with dynamic activity.

Calcium plays a role during contraction of both skeletal and cardiac muscle, but there are important differences in the mechanisms leading to increased calcium concentration and contraction between both muscle types. Could you explain them?

1. How is the contraction of a skeletal muscle cell different than the contraction of a smooth muscle cell? How does this aid in each muscle cell's function? 2. What is the purpose of myoglobin in slow-twitch muscle fibers? Why is there more myoglobin in slow-twitch muscle fibers than in fast-twitch fibers? 3. What is the purpose of gap junctions in cardiac muscle cells and some smooth muscle cells?
