5. To reduce one molecule of O2,
________ electron(s) must be passed
through the electron transport chain and
________ molecule(s) of NADH is(are)
oxidized
a. 1; 1
b. 4; 4
c. 1; 2
d. 4; 2


Sagot :

Answer:

d. 4; 2

Explanation:

To reduce one molecule of O2, 4 electrons must be passed through the electron transport chain and 2 molecules of NADH are oxidized. So the correct option is D.

What is the electron transport chain?

A chain of compounds known as the "electron transport chain" uses the electrons from an electron carrier to create a chemical gradient. It could function as the fuel for oxidative phosphorylation. The molecules that make up the chain include peptides, proteins, enzymes, and other substances.

Oxidative phosphorylation is a highly effective way for producing large amounts of ATP. A crucial component of the metabolic process is ATP. ATP is produced as a result of the transport of electrons from the electron acceptor to the electron donor. In the electron transport chain, it is one of the crucial stages. The most ATP is created in this phase of cellular respiration compared to any other phase.

Therefore the correct option is D.
