S‑adenosylmethionine (abbreviated adoMet or SAM) is a methyl group donor in numerous metabolic pathways, including the metabolis
m of lipids and amino acids. Which of the following descriptions of S-adenosylmethionine are accurate? A. The adenosyl group is linked to methionine via C4 and the β carbon of methionine.
B. The methyl group originally attached to the sulfur atom of methionine is transferred to an acceptor.
C. After ATP is cleaved, inorganic phosphate is added to C5 of the intermediate.
D. The transfer of the methyl group from adoMet to an acceptor yields S‑adenosylhomocysteine.
E. ATP is cleaved to PiPi and PPiPPi in adoMet synthesis.
The transfer of the methyl group from adomet to an acceptor yields s adenosylhomocysteine.
Explanation:
S- adenosine methionine is a co substrate and one of the naturally occurring sulfonium ions in the body. It is synthesized from methionine which is abundant in animal derived protein. It is metabolised in the liver where it is converted to S adenosine methionine by the enzyme methionine adenosyltransferase. It involve the transfer of methyl group. It is use in medicine as alternative aid to reduce depression.
Answer: the correct option is C(communicate through sign language)
Explanation:
Chantek the orangutan is one of many nonhuman primates that scholars have used to draw conclusions about the origins of human language because they seem to be able to communicate through sign language. Taught by American anthropologists Lyn Miles and Ann Southcombe Channel the orangutan learnt how to communicate using that American sign language.
I believe (B) is the best option due that it mentions the reason causing natural selection with limited supplies competition increases making it more likely for the strongest individuals to survive
