The element selenium has the atomic number of 34 while aluminium has atomic number of 13. The electronic configuration of selenium is 2, 8,18, 6 while that of aluminium is 2, 8, 3. This means that, selenium has six electrons in its outermost shell, this allows selenium to have variety of valence numbers. Aluminium on the other hand has only three electrons in its outermost shell. Aluminium will be more ready than selenium to give away its valence electrons in order to attain the octet form.  Selenium belongs to the group VIA while aluminium belongs to group IIIA. The group that an element belongs to determine the number of electron in its outermost shell.<span />

Which of the following statements about NADPH and/or NADH is not true? Choose one:
inn [45]

Answer:

NADPH is an activated carrier molecule that is used primarily by plants (NOT TRUE)

Explanation:

NADPH is indeed an electron carrier molecule that participates in various metabolic (anabolic) reactions carried out by plants, but it also participates actively in metabolic (anabolic) reactions carried out in animal tissues, this means that it is used by the cells of the human body as well.

A very important metabolic process in which the NADPH is produced is during the glucose 6-phosphate oxidation into phosphate pentoses through the pentose phosphate pathway. In this process NADP+ is the main electron acceptor, so when it is reduced it produces NADPH. <u>This NADPH is very important for the synthesis of fatty acids, cholesterol and various steroid hormones.</u>
