MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...

MCAT Organic ChemistryWhat are the four rules for writing resonance structures? - correct answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - correct answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple b...

MCAT practice questionsA stroke patient comprehends speech but cannot move her mouth to form words. Which of the following brain areas is likely affected? ■Broca's area ■Wernicke's Area ■Arcuate fasciculus ■Superior temporal gyrus - correct answer Broca's area (Broca's area governs the motor function of language. A stroke that affects Broca's area will leave receptive language intact, but word formation will be affected. A stroke affecting Wernicke's area, choice (B), will make...

MCAT Study Setcovalent bond formed via the sharing of electrons between two elements of similar EN bond order refers to whether a covalent bond is a single, double, or triple bond. As bond order increases, bond strength increases, bond energy increases, bond length decreases ionic bonds formed via the transfer of one or more electrons from an element with a relatively low IE to an element with a relatively high electron affinity - cation: postiive - anion: negative

MCAT - CARSThe CARS Section - correct answer 90 minutes to answer 53 questions divided among 9 passages (ranging from 500 - 600 words) Each passages has 5 - 7 questions You must analyze a passage's rhetorical and logical structure and be able to assess relationships between information given in the passage and new outside information. Passages - correct answer Half the passages will be in the humanities and half will be in the social sciences Humanities: architecture, art, dance, et...

MCAT 2023Phase Diagram - correct answer a graph showing the conditions at which a substance exists as a solid, liquid, or vapor a line separates the regions that correspond to the solid and liquid phases. For most substances, since the solid phase is denser than the liquid, this line has a positive slope. This indicates that it is possible to convert the liquid substance into solid by increasing pressure. Since the opposite is true for water, however, the line between these regions has a nega...

MCAT Bio/Biochem 2022What happens during non competitive binding? - correct answer binds at allosteric site How are peptide bonds formed? Broken? - correct answer dehydration synthesis hydrolysis What is the tertiary structure of a protein? - correct answer 3D structure including bending from hydrophilic/hydrophobic interactions R groups What is the quaternary structure of a protein? - correct answer interactions between different polypeptide chains in proteins composed of more than ...

MCAT Biology Central Dogma - correct answer DNA → RNA → Protein Purines - which bases? - how many rings? - correct answer Pyrimidines - which bases? - how many rings? - correct answer Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine." Phosphodiester Bond - correct answer Joins one nucleotide to the next; between the 3rd C of one ribose and the 5th C of the other to create the sugar-phosphate backbone Directionality of DNA (convention) - correc...

MCAT Psych/Sociology from 132 ScorerBiopsychosocial approach to health and illness - correct answer Illness is determined by a variety of influences, rather than a single cause. The causes and effects of illness can be examined at multiple levels in the life of an individual, and no single level provides the whole picture. Collecting info about psychosocial context is key to the understanding of physical health and illness. Biomedical approach to health and illness - correct answer Disease is...
