How does NAD+ become NADH? Why does this electron transfer (NAD+ to NADH) occur? How does chemiosmosis relate to oxidative phosphorylation? Explain glycolysis and how glucose is broken down into two molecules of pyruvate. How much NADH is produced during oxidative metabolism?
How does redox help explain the role of NADH, FADH 2 and NADPH in cellular respiration and photosynthesis? When the lights are on, the concentration of NADP+ is about the same as the concentration of NADPH in a chloroplast. What would happen to the concentration of these two molecules when...
From this point, G3P is phosphorylated in a step that also produces NADH from the oxidized form NAD+, and then the two phosphate groups are given up to ADP molecules in subsequent rearrangement steps to produce two ATP molecules along with the end carbon product of glycolysis, pyruvate. Sinc...
GAPDH converts glyceraldehyde-3-phosphate (G3P) and NAD+ into 1,3-bisphosphoglycerate (1,3-BPG) and NADH. It also plays an important role in aerobic glycolysis and has been found to be upregulated in the contexts of several kinds of cancer, but the exact cause of the upregulation remai...
Even the methylation status of the mitochondrially encoded gene NADH dehydrogenase 6 (MT-ND6) changes as a result of regular physical activity (Pirola et al., 2013). Recently, it has been discovered that natural patterns of sleep modulate the methylome in the brain. In fact, a regular 24-...
2012). This raises the question, what role does organellar gene expression play in signaling or regulating the expression of nuclear genes for proteins that may be found in the same protein complexes? Further investigations need to be carried out to answer these questions. Furthermore, a greater...
What is the main difference between the types of metabolic reactions that require NAD+/NADH and NADP+/NADPH? How does endurance training affect cortisol secretion? The Reason Why The Body Increases Heart Rate When The Temperature of the Body Rises What diet promotes the synthesis of ketone bodies...
Although it is true that bananas contain serotonin, it does not cross the blood–brain barrier 56.α-Lactalbumin, a minor constituent of milk, is one protein that contains relatively more tryptophan than most proteins. Acute ingestion of α-lactalbumin by humans can improve mood and cognition in...
During the famine phase, expression of the growth associated enzymes is reduced and when the organic substances become accessible again, bacterial strains that are capable of compiling PHAs as carbon storage, are in a superior position and become dominant (Koller et al., 2017, Serafim et al., ...
How does NAD+ and NADH regulate glycolysis and fermentation? (a) Why do NADH and FADH_2 yield different amounts of ATP? (b) Why don't all the NADH produce the same amount of ATP? How are mitochondria in eukaryotic cells similar to bacteria that use aerobic respiration?
