As hinted in the question, the cross bridge cycle is a
series of molecular events that occur after excitation of the sarcolemma. A
cross bridge is formed when a myosin head bound to actin. The cross bridge
cycle depends on the presence of calcium ions
<span>This is a true statement. The quill gives a much softer appearance to the pen and a much higher level of control over the ability to make fine strokes. In addition, the quills can be used with dipped ink as a way of setting just how dark or how light the stroke is to be made.</span>
This is correct, because aerobic is more efficient than anaerobic, making it preferable. Cellular respiration is energetically more efficient than anaerobic respiration.
<h3>Cellular respiration and anaerobic respiration </h3>
Cellular respiration refers to the generation of energy in the form of ATP in presence of oxygen.
Conversely, anaerobic respiration generates energy (ATP) in absence of oxygen.
Cellular respiration is an energetically more efficient pathway than anaerobic respiration, thereby facultative organisms generate ATP by cellular respiration when it is possible.
