If you just ate a KrispyKreme Donut, your blood sugar levels will rise.

this is an example of a/an (A. response/ B. stimulus / C. integrator/ D. effector/ E. receptor).

Beta cells in pancreatic islets detect the blood sugar concentrations so they act as (A. response/ B. stimulus / C. integrator/ D. effector/ E. receptor) in the homeostatic feedback loop.

There is a chemical mechanism that switches on the genes on the DNA so that a protein may be synthesized and released to maintain homeostasis if need be. This chemical mechanism only activates if blood sugar levels reach a certain threshold. If they don't rise, then this mechanism won't activate. This mechanism very effective acts as a/an (A. response/ B. stimulus / C. integrator/ D. effector/ E. receptor) in the homeostatic feedback loop.

If, and only if blood sugar levels rise past a certain point, the cells will release a hormone called insulin. Insulin acts as a/an (A. response/ B. stimulus / C. integrator/ D. effector/ E. receptor) in a homeostatic feedback loop.

If insulin is secreted, the liver will absorb excess blood sugar and levels will return to more optimal levels. This is an example of a (A. response/ B. stimulus / C. integrator/ D. effector/ E. receptor) by the body to maintain homeostasis.
