The overall reaction that occurs when sugar is metabolized is C 12 H 22 O 11 ( s ) + 12 O 2 ( g ) → 12 CO 2 ( g ) + 11 H 2 O ( l ) For this reaction, ΔH ° is -5650 kJ and ΔG° is -5790 kJ at 25°C. (a) If 25% of the free energy change is actually converted to useful work, how many kilojoules of work are obtained when one gram of sugar is metabolized at body temperature, 37°C? (b) How many grams of sugar would a 120-lb woman have to eat to get the energy to climb the Jungfrau in the Alps, which is 4158 m high? ( w = 9.79 × 10 − 3 mh , where w = work in kilojoules, m is body mass in kilograms, and h is height in meters.)

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

Dr. Mendel asked his BIOL 260 class what their height was and what their
parent's heights were. He plotted that data in the graph below to determine if
height was a heritable trait.
A. Is height a heritable trait? If yes, what is the heritability value? (2 pts)
B. If the phenotypic variation is 30, what is the variation due to additive alleles?
