Step 11 of skeletal muscle contraction:.
A) Inorganic phosphate is released from myosin head pulls actin filaments (power stroke) toward the center of the sarcomere.
B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.
C) ATP breaks down into ADP and inorganic phosphate.
D) Myosin head resets for another cross-bridge cycle Myosin head binds to actin binding site. (Cross-bridge

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
