1. colorado science standard #4 states: "the energy for life primarily derives from the interrelated processes of
photosynthesis and cellular respiration. photosynthesis transforms the sun's light energy into the chemical
energy of molecular bonds. cellular respiration allows cells to utilize chemical energy when these bonds are
broken." what does this science standard mean to you?

The paragraph illustrated in the question reminds me the first law of thermodynamics.

Explanation:

According to the first law of thermodynamics or law of energy conservation theory states that the total amount of energy of the universe always remains constant.Energy can neither be synthesized nor destroyed.Energy can only be transformed.

   Both photosynthesis and cellular respiration obey the law of energy conservation or the first law of thermodynamics.Because during photosynthesis the light energy is converted to chemical energy that is stored in the chemical bonds present in glucose.

  Whereas during cellular respiration the glucose is broken down  by oxidation to release free energy in form of ATP.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
