Answer:
Leucine, isoleucine and lysine are classified as <u>essential amino acids.</u>
Explanation:
Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.
The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).
There are total <u>21 amino acids in a human body</u>.<em><u> They can be divided into two types: Essential amino acids and Nonessential amino acids</u></em>
Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.
<u>Example: leucine, isoleucine, lysine.</u>
<u>Therefore, leucine, isoleucine and lysine are classified as essential amino acids.</u>
Hey there!:
1 mole O2 ----------------- 22.4 L ( at STP )
( moles O2 ) -------------- 2.50 L
moles O2 = 2.50 * 1 / 22.4
moles O2 = 2.50 / 22.4
moles O2 = 1.12*10⁻¹
Answer B
Hope that helps!
