1. What is wrong with the following equation for biological redox?
NAD+ + FAD→NADH + H+ + FADH2
NAD+ +2H+ + 2e- --> NADH + H+ - Reduction (gain of 2e-)
FADH2--> FAD + 2H+ + 2e- - oxidation (loss of 2e-)
overall reaction will be: (redox reaction)
NAD+ + FADH2 --> NADH + H+ + FAD
Biology Help. 15.) "Explain the purpose of making NADH in glycolysis, the Grooming Phase, and Krebs Cycle, and FADH2 in the Krebs Cycle." 16.) "What is removed from the catabolic products of glucose during NAD+ to NADH and the reduction of FAD to FADH2?"
What reactions demonstrate reduction? Select all that apply FAD+ + 2H + 2e-→FADH2 O2→O2- Fe+2→Fe+3 NADH→NAD+ + e- + H
In one step of glycolysis, glyceraldehyde 3-phosphate is oxidized by NAD+ to yield 3-phosphoglycerate and NADH. 1) Consider that reaction, in the direction written. Which chemicals) is(are) losing electrons, and which chemical(s) is(are) gaining electrons? It's best to answer this in a clear complete sentence. 2 2 2 Table 10-2 Standard Reduction Potentials for Redox Pairs of Biological Relevance* Redox Pair Number of (oxidized form → reduced form) Electrons E.(V) acetate pyruvate 2 -0.70 succinate → a-ketoglutarate 2 -0.67 acetate...
Suppose NAD+ is unavailable because NADH cannot be oxidized due to a mutation in the NADH dehydrogenase (Complex I). If FAD could substitute for all NAD+, how would this affect the total ATP produced by the complete oxidation of glucose? How would it affect the total ATP produced by the complete oxidation of a 20C fatty acid? (Give specific numbers and show how you reached this number.) Based on what you know about redox potentials, would this be possible?

Be able to write out the biochemical equations for glucose respiration and photosynthesis AND label the oxidizing and reducing agents in each reaction. 3. What are the three stages of cellular respiration and where does each occur in the cell? 4. During cellular respiration, what is the role of each of these molecules: glucose, pyruvate, ATP, NAD+, FAD, NADH, FADH2, acetyl CoA, CO2, H2O, and O2? 5. For each...

1.The deceased patient had NAD+ and NADH levels very different
from healthy subjects, but why isn't his glucose level drastically
different?
2. Please predict the levels of FAD and FADH2 . Explain. Taking
note he had cyanide poisining
According to the result, the patient has: 1. Massive damage to the mitochondria 2. The metabolite level results of (see table below) Metabolite Levels found in patient (u.M) Normal levels (uM Glucose NAD NADH 80 10 400 100 75 50
