The zombie apocalypse is here. you have holed up in a biochemistry lab and have only the chemical shelf for food. on the shelf you see: various monosaccharides, and various sugar alcohols (where the carbonyl of the sugar has been converted to an alcohol). would sugars or sugar alcohols give you more energy per carbon? why? (assume all of these will be transported to your cells equally well.)

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
