MCAT Practice Questions Why are triacylglycerols used in the human body for energy storage? A) They are highly hydrated, and therefore can store lots of energy. B) They always have short fatty acid chains, for easy access by metabolic enzymes. C) The carbon atoms of the fatty acid chains are highly reduced, and therefore yield more energy upon oxidation. D) Polysaccharides, which would actually be a better energy storage form, would dissolve in the body. - correct answer C Triacylglyce...

MCAT Biology | Latest Version | 2024/2025 | Already Graded A What is the role of the endoplasmic reticulum in protein synthesis? The endoplasmic reticulum aids in protein synthesis by providing a site for ribosomes to translate mRNA into proteins and assisting in the folding and modification of these proteins.
