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.

Answer: Option D.

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.

What is true about the absorption and storage of fat-soluble versus water-soluble vitamins in the body?
rodikova [14]
The right answer is "<span>fat soluble are stored in the liver and fatty tissue ...".

Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat".These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.

"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>

Brain, spinal cord, nerves

The brain controls thought, behavior, emotion, memory, and basic life functions. The brain is also the origin of control over body movement. The spinal cord connects the peripheral nervous system (PNS) to the brain; nerve impulses reaching the spinal cord through sensory neurons are transmitted up into the brain. Nerves primarily involve control and coordination of all parts of the body.

The nervous system interacts with every other organ system. For example the hypothalamus in the brain controls the pituitary gland and tells it when to produce hormones, this shows that the nervous system interacts with the endocrine system.

Hope this helps :)
