Im kinda puzzled on that particular question
Answer:
FADH2 has a lower (less negative) redox potential than NADH does
Explanation:
Flavin Adenine Dinucleotide (FAD) and Nicotinamide Adenine Dinucleotide (NAD) are redox cofactors that play important functions for mitochondrial activity and cellular redox balance. Both coenzymes exist in two forms: an oxidized and a reduced, which are abbreviated as NAD/FAD and NADH/FADH2, respectively. These reduced forms (NADH and FADH2) are produced in the Krebs cycle during respiration. FADH2 has lower redox potential than NADH because FADH2 is only capable of activating 2 proton pumps, while NADH can activate 3 proton pumps during the electron transport chain, thereby FADH2 generates a minor number of ATP molecules than NADH.
The reaction is a decomposition…
… because one substance is forming two other substances.
It is also a <em>reduction-oxidation reaction</em> because the <em>oxidation number of N decreases</em> from +5 to +3 and the <em>oxidation number of O increases</em> from -2 to 0.
<em>Answer:</em>
- Li and K have same chemical properties
- O and Se have same chemical properties
- He and Ar have same chemical properties
<em>Explanation:</em>
According to modern periodic table, the elements present into same group group have same chemical properties due to same valence shells electrons.
<em> Li and K have same chemical properties: </em>
Both these elements are present in same group i.e group 1 known as alkali atoms. Almost all alkali metals have same chemical properties.
<em> O and Se have same chemical properties</em>
Both these elements are present in same group VI A. The elements present in same group have same chemical properties.
<em>He and Ar have same chemical properties</em>
Both these elements are present in same group VIII A called it noble gases. The elements present in same group have same chemical properties both are inert.
