Biology

Although copper is easy to extract, it is becoming very difficult to find or obtain ores rich in copper compounds.Since rare things (in this case copper ores) are difficult to obtain, they are usually more expensive than things that are easily found (iron).

According to this article, why does the immature prefrontal cortex lead to<br> conflict for teens?
aivan3 [116]

Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

To which substance does ferredoxin transfer an electron?
Sonbull [250]

The right answer is NADP+.

Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:

2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH .
