Answer:
c. decarboxylation of an a-keto acid.
Explanation:
Decarboxylation refers to the removal of the carboxyl group from a carboxylic acid and thus releasing carbon dioxide. Decarboxylases are enzymes that speed up the removal of the carboxyl group from acids. These reactants could be amino acids, alpha-keto acids, and beta-keto acids. Biotin is known to catalyze the decarboxylation of malonyl CoA to acetyl CoA during fatty acid synthesis.
Malonyl CoA is converted to acetyl CoA after decarboxylation assisted by biotin also known as Vitamin H. Alpha keto acids are involved in fatty acids synthesis and Malonyl CoA is an alpha-keto acid because the keto group is located in the first carbon near the carboxylic acid group. Keto acids have both a carboxyl group and a ketone group.
Answer:
<span>In ionic compounds, <u>Metals</u> lose their valence electrons to form positively charged Cations.
Explanation:
Metals have the ability to loose elctrons readily. For example metals of Group IA and Group IIA readily looses electrons in order to obtain Noble Gas Configuration. On the other hand Non-metals tends to gain electrons and acquire negative charge. While Ions are made when an an element gain or loose electrons. After loosing electrons element get positive charge which is called as Cation while on gaining electron it gets negative charge called as Anion.</span>
I would say it is answer choice C, Laws are based on proven hypothesis by many different scientists.
I think that type of rock is call Igneous rock because the igneous rock is molten rock from volcanoes.
Faster molecules have fewer collisions than slower molecules is True about molecular speed.
<h3>What is Molecular speed?</h3>
Molecular speed refers to the average distance gases or molecules travelled atca particular time rate.
It is valid in ideal gas, where the molecules do not interact with others.
Average molecular speed = Square root (3 (ideal gas constant) * (Temperature)/m)
Therefore, Faster molecules have fewer collisions than slower molecules is True about molecular speed.
