QUESTION 1
According to the sliding-filament model of contraction, how does muscle contraction occur?
The myosin heads propel the actin myofilaments toward the center of the sarcomere; this pulls the Z disks closer tog
sarcomere and the entire muscle.
The actin heads propel the myosin filaments toward the center of the sarcomere; this pulls the Z disks closer together
sarcomere and the entire muscle.
The myosin heads propel the actin myofilaments toward the center of the sarcomere. This causes the myofilaments to
disks closer together to shorten the sarcomere and the entire muscle.
Both the actin and myosin myofilaments shorten, which shrinks the sarcomere and pulls the Z disks closer together. A
together, the muscle contracts.

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
