Name the two muscle compounds that store energy in the form of high-energy phosphate bonds.
To determine: The name of two muscle compounds that store energy in the form of high-energy phosphate bonds.
Introduction: The contraction of skeletal muscles results in the movement of body parts. The energy is required in the movement of muscles. The basic unit of muscle contraction is known as sarcomere, which is formed by the multiple repeating units of actin and myosin filaments.
Explanation of Solution
The main objective of muscles is to support the locomotion or movement of an organism. The muscle fibers collectively form the “muscular system.” The system fulfills the essential requirements which are required for the mechanical forces and generates the motion necessary for the motility of the organism. The two muscle compounds that store energy in the form of high-energy phosphate bonds are phosphocreatine and ATP.
The two muscle compounds that store energy in the form of high-energy phosphate bonds are ATP and phosphocreatine.

- List the Functions of ATP in Skeletal Muscle Contraction?arrow_forwardDescribe the protein structures involved in muscle contraction. Illustratearrow_forwardMuscle contraction involves a protein conformational change called the power stroke. Where ultimately does the energy come from that allows a series of conformational changes involved in the power stroke? O Ca2+ O ATP hydrolysis O Actin polymerization O GTP hydrolysisarrow_forward
- Outline the molecular mechanism for skeletal muscle contraction. At what point is ATP used and why?arrow_forwardDiscuss why fast glycolytic fibers have more glycogen stores than slow oxidative fibers.arrow_forwardSkeletal muscle fibres are very metabolically active and are adapted to create a lot of ATP from aerobic cellular respiration. Additionally, cells require other things to stay alive. Explain how the following three organ systems contribute to allowing a muscle cell to carry out its roles: a) Respiratory system b) Cardiovascular system c) Gastrointestinal system asap please.arrow_forward
- Name the system that provides a ready supply of phosphocreatine to muscle cells and describe where the different components of this system take place.arrow_forwardWhy is adenosine triphosphate (ATP) used for muscle contraction?arrow_forwardStriated muscle twitch force reaches a maximum after nearly all of the calcium is pumped out of the sarcomere and back into the sarcoplasmic reticulum because: A.) sarcomere activation is not dependent on calcium B.) calcium inhibits force production C.) calcium interferes with ATP hydrolysis D.) Calcium is the initial switch to turn the actin thin filament on and then crossbridge kinetics define how long the thin filament will remain active E.) A & Barrow_forward
- For the skeletal muscle, hydrolyzation of ATP: Group of answer choices At the myosin head gives rise to the generation of power stroke. At the actin G-molecule gives rise to the generation of power stroke. At the myosin head give rise to the rotation of myosin head to the "cocked back" position. At the actin G-molecule give rise to the rotation of myosin head to the "cocked back" position.arrow_forwardWhy does muscle fatigue occur? since sarcomeres within skeletal muscles are rigidly aligned with each other what do you think excessive stretch or compression (remember the basic structure of the sarcomere with overlapping thin and thick filaments and the length-tension relationship) will do to the force generation of a muscle contraction?arrow_forwardDescribe the two mechanisms by which muscle glycogen is broken down to glucose (glycogenolysis) for use in glycolysis. Which one is activated at the same time as muscle contraction?arrow_forward
