1. A muscle displaces a 50 Gram weight a distance of 2.0 CM in a direction normal to the earth's surface. Calculate the work (W). done on the load, and express your answer in a consistent system of units.
The contractile process has released an amount of energy which is equivalent to or greater than W. In general the recovery processes must supply an energy equivalent E which is >W to return the contractile system to its initial state.
Discuss the non conservative processes which account for the fact that E is <W in terms of the muscle models of Andrew and/or Hugh Huxley.
2. In flash studies of photo synthesis, illumination might be specified in effective trolands. Discuss the type of information about the photosynthetic process) which must be known if the unit of illumination is to make any sense at all in this context. Is this information readily available?
A somewhat less irrational approach involves specifying the luminance in Lambert's. Discuss the disadvantage of this system in terms of the definition of this illuminence unit and a rough outline of the action spectra of the photosynthetic process in green plants.
