Ovulation Inflammation Digestion ©GRACEAMELIA 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED FIRST PUBLISH OCTOBER 2024 Page 4/36 Both A and B are correct All of the above are correct - Ans:-All of the above are correct Inorganic nitrogen is initially assimilated into which of the following amino acids Glycine Alanine Serine Glutamine Leucine - Ans:-Glutamine Why do most naturally occurring fatty acids have cis double bonds in them? The cis double bond introduces a kink in the chain. The cis double bond remains results in relatively no change in the fatty acid direction. The double bond results in a bend in the molecule elevating the melting point of the molecule. ©GRACEAMELIA 2024/2025 ACADEMIC YEAR.
