What reactions demonstrate reduction? Select all that apply
FAD+ + 2H + 2e-→FADH2
O2→O2-
Fe+2→Fe+3
NADH→NAD+ + e- + H
What reactions demonstrate reduction? Select all that apply
Answer- A. FAD+ + 2H + 2e-→FADH2
The reduction in the gain of an electron.
oxidation is the loss of an electron.
O2→O2- ,
Fe+2→Fe+3
NADH→NAD+ + e- + H
here oxygen is losing an electron and
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!
What reactions demonstrate reduction? Select all that apply FAD+ + 2H + 2e-→FADH2 O2→O2- Fe+2→Fe+3 NADH→NAD+...
Which of the following reactions are non spontaneous? A. Fe+2 > e' + Fe+3 B. pyruvate + 2H+ + 2e' > lactate C. ATP > ADP + Pi D. NADH + H+ > 2e' + NAD+ + H+ E. FAD + 2H+ +2e' > FADH2
For the reaction: L-Malate + NAD⁺ ← → Oxaloacetate + NADH
ΔE' = -0.154
n=2
T=298 K
using the equation
ln (Keq) = (nFΔE'৹)/(RT)
Find Keq?
I know this sounds just plug and chug but am confused about the
signs of the numbers when plugged in. Please only answer if you're
of what you're doing!

This is for biochem. Please answer and explain why?
As a representation of the respiratory chain, what is wrong with this picture? There are 4 deliberate errors. Select all that apply NADHFAD ног Coa 1. NADH is oxidized by FMN, not FAD. 2. NADH is oxidized by CoQ, not FAD. 3. Reduced flavin (FADH2 or FMNH2) is oxidized by CoQ, not CoQH2. 4. O2 is reduced to H2O, not H202 5. Cyt c, accepts e-from cyt a-a3, and is then...

Select all true statements regarding ETC: High-transfer-potential electrons from NAD+ and FAD+ are responsible for the oxidation of oxygen to synthesize ATP ETC components are arranged so that electrons always flow to the component with increasing reduction potential FADH2-derived electrons yield more ATP than the amount of ATP produced from NADH-derived electrons None of these statements are true. Electron flow from ETC generates proton gradient
