Pretty sure the answer is oxygen, as it is produced in photosynthesis and consumed in respiration.
The approach to development that suggests that there are five levels of the environment that simultaneously influence individuals is Bronfenbrenner's bioecological approach.
These five levels include: microsystem, mesosystem, exosystem, macrosystem, and chronosystem. All of these levels have an impact on human beings together, and at the same time, and shape people to become the persons they are throughout their lives.
The answer is; Early steps consume energy from ATP, and later steps store an increased amount of energy in ATP and NADH
In the initial stage (energy consuming), 2 ATPs and consumed to convert glucose to the high energy fructose-1,6 biphosphate. The fructose-1,6 biphosphate is later split into 2 glyceraldehyde-3-phosphate (G3P). In the energy-releasing phase, each G3P is used to generate 2 ATPs and an NADH are released. Therefore, there is a net positive energy of 2 ATPs and 2 NADHs.
