Why is NAD+ to NADH a reduction? Why does NAD+ reduction release energy? Why is pyruvate reduced during fermentation and not cellular respiration? Why is FAD reduced in pyruvate dehydrogenase complex and then NAD is reduced? Why does NAD+ accept two electrons?
Why does NAD+ accept two electrons? How does NAD+ become NADH? Why does this electron transfer (NAD+ to NADH) occur? What role do NAD+ and FAD+ have in the electron transport chain? Explain. Where does glycolysis take place? Which molecules are made during glycolysis? Where does the oxy...
Step-by-Step Solution:1. Understanding the Context: When oxygen (O2) is not available in muscle cells, they undergo anaerobic respiration instead of aerobic respiration. This occurs during intense exercise when
For respiration, the sources of electrons are typically reduced electron carriers like NADH and FADH{eq}_2 {/eq}, while for photosynthesis, the source of electrons are typically high energy electrons from reaction center pigment molecules.
A) NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle. NADH can then donate electrons, when it is oxidized, to the electron transport c We defined the oxidation and the reduction reactions involving NADH that are involved in Complex I of the electron ...
