Consider the two-step metabolic pathway: a—(enzyme 1)—> b—(enzyme 2)—> c how would inactivating enzyme 1 affect the concentrations of molecules a, b, and c relative to what they would be if the pathway were fully functional? see section 8.5 (page 185) .

Answer;

D. A would increase; B and C would decrease

Explanation;

-Enzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors.

-Inactivating enzyme 1 mean that the concentrations of molecules A would increase because enzymes is not acting on it to produce product B, which is the substrate for enzyme 2, thus both B and C would decrease relative to what they would be if the pathway were fully functional.

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.
