While Science Cannot Describe "Thinking" in Physical Terms, We Are

Multiple Choice

While science cannot describe "thinking" in physical terms, we are certain that the process involves metabolism inside brain cells. With positron emission tomography (PET scan) , it is possible to inject short-lived isotopes and image the regions of the brain that have the most active metabolism during various mental activities. However

A) thought cannot be linked to cell processes because energy is not related to matter.
B) since thoughts can occur over and over, the requirement for a continual input of energy to prevent entropy does not apply to this cell activity.
C) the cellular energy expended in thinking must be less than the chemical bond energy supplied in food to these brain cells.
D) "thinking" is beyond the scope of science to study.
E) "thinking" is not a cellular process and therefore does not require energy.
