question 8. false
The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
It will cause vasodilation of blood vessels in the brain.
CO2 is one of the metabolic end products that can alter the
tone of the blood vessels in the brain. High CO2 levels cause vasodilation,
which may cause headache, whereas low CO2 levels cause vasoconstriction, which
may cause lightheadedness. The statements included in the other options are
