Describe the many expected training adaptations in the muscles targeted by a 6-month endurance/aerobic training program (e.g., cycling, running, swimming):

Describe (if you only list then no credit) the three mechanisms of ATP production in a skeletal myocyte that needs more ATP for muscle contraction:

Using the drop down boxes, number the following items (1-6) with #1 as the largest size to #6 as the smallest size: Fiber Actin/Myosin Trapezius Myofibril Fascicle Sarcomere

Describe three different ways ATP is used/utilized/spent by skeletal myocytes for contraction/relaxation:

While running a marathon (okay maybe more realistically, a 10-K), what source will supply the majority of ATP needed during the running muscle contractions?

The function of the T-tubules or Transverse Tubules in a skeletal myocyte is to:

Assuming you are a teaching assistant in BIOL 430 in the near future. Help a student in your “office hours” by describing the role of each of the following in muscle function – actin, myosin, troponin, and tropomyosin:

The spread of an action potential very quickly from one location of a cell to another location in the same cell is due to which of the following?

Describe the function of chemically-gated channels (also called ligand-gated) using an example in the body AND describe the function of voltage-gated channels using an example:

(Please read carefully) List the specific sequence of events that take place at the neuromuscular junction when a motor neuron excites (or activates) a skeletal myocyte. Start at the axon and stop at the end of the events occurring in the motor end plate of the muscle fiber:
