Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

Which phrases describe what the rock cycle shows? Check all that apply.
Sonja [21]

Answer:

How rocks change from one type to another and which processes are involved in rock changes.

Explanation:

We know that there are three types of major rocks. Those are: igneous, sedimentary, and metamorphic. The rock cycle describes how the three major rock types convert from one to another.

Changing in rocks happens as a result of natural processes that are taking place all the time. Most of the changes happen very slowly. Rocks that are in the deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them to another rock. Even at the surface, we may not notice the changes in the rocks.

Along with this, a rock cycle describes those process which involves in this rocks transformation process. It represents various environmental factors that are related to the change of the rock from one to another.
