Coenzyme Q and cytochrome c are components of the electron transport chain. TRUE

The major reactants in the electron transport chain are O 2 and either NADH or FADH 2. TRUE

In the electron transport chain, a series of reactions moves electrons through carriers. TRUE

The electron transport chain operates independently of other metabolic processes. FALSE

The electron transport chain produces two ATP. FALSE

Explanation:

Electron transport chain is a series of reactions in which electrons are transferred from an electron carrier to oxygen molecules in living cells. It is together with chemiosmosis called oxidative phosphorylation and it occurs in the mitochondria of the cell.

The major reactants in electron transport chain are oxygen molecule which sits at the end of the chain to receive electrons from a carrier; either NADH or FADH2 serving as the electron carrier which transfers electrons to oxygen molecules splitting it to enable it accept proton from the matrix to form water. The energy released in electron transport chain is transferred as a proton gradient from which chemiosmosis synthesize the ATP needed by the body. The two components of oxidative phosphorylation, that is the electron transport chain and chemiosmosis are closely connected and one can not work independently of the other. This is because the proton gradient caused by energy generated from the electron transfer in electron transport chain is needed for chemiosmosis. Electron transport chain doesn't generate ATP directly but together with chemiosmosis produces the bulk of the cell's ATP. Two molecules are from Glycolysis and two molecules from citric acid cycle, about 15 molecules of ATP from 6NADH and about 3ATPs from 2FADH2. The coenzyme Q and cytochrome c are major components of the electron transport chain. These substances are links in the transfer of electrons from NADH or FADH2 to oxygen.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
