Adding dnp to mitochondria alters the electron transport chain in what way? (a) atp continues to be produced but oxygen is no longer consumed (b) atp is no longer produced and neither is oxygen consumed (c) atp is no longer produced but oxygen continues to be consumed (d) the proton gradient is unaffected (e) the electron transport chain interrupts the transfer of electrons

The correct option will be option C.

Explanation:

2,4-Dinitrophenol or DNP is a protonophore molecule which can leak the protons and leads to affect the production of ATP in the mitochondria.

DNP is the best agent known for uncoupling the oxidative phosphorylation as it uncouples the phosphorylation of adenosine diphosphate (ADP) from ATP synthase.   It leads to the low production of the ATP during oxidative phosphorylation and most of the energy is converted to heat.  It does not effect the electron transport chain, it continues.

Thus, option C is the correct answer.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
