Which bond of the ATP molecule is broken in order to release energy?

• A

• B

• C

• D

Place the following steps for a muscle contraction in order from beginning to end

• Calcium ions are released from sarcoplasmic reticulum

• Ca2+ binds troponin causing tropomyosin to expose binding sites on actin

• Myosin heads bind to actin forming crossbridges

• Actin filaments are pulled toward center of the sarcomere & The sarcomere shortens and the muscle contracts

• Action potential is generated
