Which of the following is an accurate comparison of skeletal muscle tosmooth muscle? Smooth muscle consumes more ATP to maintain a given level of muscle tension. Smooth muscle contracts more rapidly but relaxes more slowly. Smooth muscle depends on a nerve fiber to supply the calcium needed for contraction. Smooth muscle contracts and relaxes more slowly. Smooth muscle contracts more slowly but relaxes more rapidly.

Which characteristics of smooth muscle cause it to use less energy when contracting compared to skeletal muscle? There is one correct answer: Smooth muscle pumps less calcium per unit time. Smooth muscle does not have myosin ATPase. The contractions of smooth muscle are faster. Smooth muscle uses glycolysis instead of oxidative phosphorylation to make ATP.

Why can smooth muscle contract over a greater length compared to other muscle types? Sarcomeres are longer than in other muscles. Calmodulin is more effective at stimulating cross-bridge cycling. There are no sarcomeres. 'Latching' allows muscles to use less energy while contracting.
