Muscle contraction represents the conversion of chemical free energy into mechanical work. What is the source of chemical energy, and what is the nature of the work at both the cellular and molecular levels?
Homework Answers
--->ATP (adenosine tri-phosphate) is the origin of chemical energy that gets converted to mechanical energy.
--->Muscle contraction results from the interaction between myosin and actin filaments that creates a movement of the muscle.
--->In the molecular level regeneration shortens the sarcomeres filaments are produced with several protein myosin molecules, when ATP binds and sparks to the myosin head it detaches in the actin filaments. Creating a contraction.

1.The hyperbolic force dependence of muscle shortening velocity results from the fact that: a. Muscle contraction is best described by a Hookean Spring model. b. Energy is dissipated by mechanical work and viscous drag, both of which depend on changes in sarcomere length. c. ATPase cycling is hyperbolically dependent on the local concentration of Actin. d. Ftot = funi*D*N e. Heat liberation by muscle is constant.

Describe what happens to when Snicker bars and Twizzlers, both physically and chemically, once they pass through your lips. In other words, trace the main ingredients (from a complex food source completely through molecular and submolecular levels) from the moment you start eating them until they are completely broken down into building blocks and cellular energy. Focus your answer on what happens to the key molecules in the food, and on the cellular aspect of these conversions. Also, describe how...

TRODUCTION Chemical processes occur spontaneously when they lower the free energy of the system. The free energy at constant temperature and ressure is the Gibbs free energy, AG, which is defined as follows: AG = AH - TAS where AG is the change in free energy of the system, AH is the change in enthalpy of the system and AS is the change in entropy of the system AG, the change in free energy, must be less than zero for...
