Anthony has been refusing to go to school. Anthony's culture places great emphasis on academic achievement and expects that young people will get no grade lower than an A, and his teacher wonders whether that may be influencing Anthony's school refusal.

Anthony has been refusing to go to school. Anthony's culture places great emphasis on academic achievement and expects that young people will get no grade lower than an A, and his teacher wonders whether that may be influencing Anthony's school refusal. This illustrates operation of the Macrosystem.

Explanation:

Urie Bronfenbrenner has developed a theory of ecosystems in which the macrosystem deals with the culture in which an individual survive. There are five differemt environmental systems that has been dealt with this system in which the individual interacts. They are mesosystem,macrosystem, microsystem, chronosystem and exosystem.

When the culture is dealt as a whole and dealing with poverty,ethnicity,status in socioeconomic context and wealth is Macrosystem. They also deal with children their studies and the working nature of their parents. The example given here deals with an individual's emphasis towards academic and the things that influence him. Thus it illustrates the operation of Macrosystem.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
