Answer:

Una teoria es un conjunto de conceptos, proposiciones y definiciones que se relacionan y son recogidas desde un punto de vista sistematico de fenomenos. Sirven para poder predecir el fenonemo. Asi que para que un fenomeno no sea mas una teoria o una prediccion tiene que haber una explicacion que confirma el fenomeno, dejando asi de ser una teoria. Eso se puede lograr con los puntos en la explicacion.

Explanation:

• Verificación del hecho y diferenciación de lo que son las opiniones.

• Documentación, averiguación del acontecimiento y contrastación de los datos que se han conseguido recabar.

• Análisis del suceso en sí teniendo en cuenta el contexto en el que ha tenido lugar.

Answer:

Electron transport inhibitors: Cyanide, Rotenone

Uncoupling agents: trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP)

ATP synthase inhibitors: Oligomycin

Transport inhibitors: Bongkrekic acid

Explanation:

Electron transport inhibitors: Cyanide, Rotenone

Cytochrome oxidase also known as complex IV in the electron transport chain, carries electrons from cytochrome c to oxygen. It is a large enzyme having 13 subunits. Subunit 1 contains two heme groups , a and a3. Electrons are tranferred from heme a to oxygen bound to heme a3. The reaction of cyanide with heme a3 blocks this process of eleron transport

.Rotenone blocks electron transfer at NADH dehydrogenase (NAD−Q(NAD−Q oxidoreductase) by preventing electron transfer from Fe-S center to ubiquinone.

Uncoupling agents: trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP)

The transfer of electrons from NADH through the respiratory chain to molecularoxygen is coupled to proton pumping from the inner mitochondrial matrix to the intermembrane space. This generates a proton motive force which is utilized in ATP synthesis. Trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP) increases membrane proton permeability, causing protons to leak back into the mitochondrial matrix, thereby uncoupling the processs of ATP synthesis and proton flux.

ATP synthase inhibitors: Oligomycin

ATP synthase is the enzyme rensponsible for ATP synthesis. It has two functional domains,: F₁ and F₀. Oligomycin binds to F₀ and blocks the proton channel preventing rotation of the F₁ subuni, thus, preventing ATP synthesis from ADP.

Transport inhibitors: Bongkrekic acid

Adenine nucleotide translocase is a transport protein that transports free ADP from the cytoplasm into the mitochondrial matrix, while ATP produced from oxidative phosphorylation is transported from the mitochondrial matrix to the cytoplasm o the cell.

Bongkrekic acid inhibits Adenine nucleotide translocase, thus preventing ATP from leaving the mitochondria and starving cells of needed energy.

Pituitary tumors are a frequent cause of over secretion of human growth hormone. Often the tumor is benign, meaning it is not cancerous.
