Answer:

Thylakoid space to the stroma

Explanation:

Electron transport chain occurs in both the mitochondria and the chloroplast which is involved in the process of ATP formation in the cell. The enzyme which catalyzes the reaction of the ATP formation is ATP synthase. The ATP synthase is composed of two subunits the CF₀ and CF₁.

The CF₁ is involved in the conversion of ADP to ATP due to the rotation of the rotor in the CF₁ unit which derives its energy from the flow of protons.

In chloroplast during the electron transport chain, the proton gets accumulated in the thylakoid lumen. These accumulated protons flow back from the thylakoid lumen towards the stroma of the chloroplast through CF₀  subunit of ATP synthase.  

Thus, the selected option is correct.

mr Goodwill [35]

Answer:

The correct answer is-ER Golgi plasma membrane

Explanation:

Rough endoplasmic reticulum contains the ribosomes on it which helps in the formation of proteins from the mRNA by the translation process. The proteins chains synthesized are pushed in the cisternae of the RER where the primary modification of proteins takes place.

Then these proteins are released towards closely associated Golgi apparatus where the further modifications and processing of proteins takes place like glycosylation, sulfation, etc.  

After the modification, the proteins are released from the Golgi in enclosed vesicles to their destination like they can be sorted in plasma membrane or lysosomes. So the correct answer is-ER > Golgi > plasma membrane.

inna [77]

Answer:

In the extracellular space

Explanation:

Disulfide bonds are interconnections between chains (or between parts of a chain) formed by the oxidation of cysteine ​​radicals, this reaction is catalyzed by specific enzymes.

Intracellular proteins have no disulfide bonds, which are more common in proteins secreted into the extracellular environment.

Disulfide bonds do not form in the cytoplasm because there are a lot of reducers in the cytoplasm (intracellular environment) , making the disulfide bonds unstable. The reducing environment of cytoplasm causes disulfide bonds (S-S) to return to the form of cysteine ​​groups (-SH).

Which class iv calcium channel blocker is exclusively administered to treat acute supraventricular tachycardia?
Likurg_2 [28]
The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem.  Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.
