In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/red
Aliun [14]

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; <em>Choice D: The change in the biochemical standard reduction potential is small.</em>

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

  • However, the necessary condition for a reversible process is therefore the quasi-static requirement.

  • The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.

Explain the phenomenon of photorespiration, including why it is thought to occur (evolutionarily speaking), and why plants have
liubo4ka [24]

Photorespiration limits casualty products of light reactions that build up in the absence of the Calvin cycle. In many plants, photorespiration is a problem because on a hot, dry day it can drain as much as 50% of the carbon fixed by the Calvin cycle.  The closing of stomata reduces access to CO2 and causes O2 to build up. These conditions favor a seemingly not useful process called photorespiration.  In most plants (C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon compound.  In photorespiration, rubisco adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and organic fuel and releases CO2 without producing ATP or sugar. Photorespiration can evolve relic because rubisco first evolved at a time when the atmosphere had far less O2 and more CO2.
