Which label in the graphic represents the energy that is released from glucose by cellular respiration? a. oxygen. b. glucose. c. energy stored as atp. d. carbon dioxide and water

The right answer is C. energy stored as ATP (the only answer refering to an energetic product).

Coenzyme ATP (produced by cellular respiration) always plays the energetic role in the enzymatic reactions by hydrolysis of one of its energy-rich bonds.

This energy can appear in many forms: in mechanical energy, as in muscular contraction; in osmotic energy, as in the Na + / K + exchanges at the cell membranes; in chemical energy, for performing syntheses of biological molecules; in caloric energy, to maintain the temperature of 37 ° C; in electrical energy, for the propagation of nerve impulses; and finally in luminous energy, in the glowworm, for example.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
