Relationship Between Work and Energy
The performance of any type of work requires energy, and (with a constant mechanical efficiency) the amt. of energy required to do a given amt. of work is always the same. Thus, we must pay energetically for any work that we do.
WORK & ENERGY
1 Kilocalorie =
a) 426.85 Kpm
b) 3087.4 ft. lbs.
c) 4,186 joules
ATP __ ADP + Pinorganic
Synthesis of ATP within metabolism (an energy requiring process) is accomplished by coupling other energy liberating reactions with ATP formation.
ATP __ + Pi + 7 Kcals liberated
ADP + Pi __ + 7 Kcals required
