3. Exemplos de Flashcards de Alto Rendimento (Biochemistry )

Nível	Frente (Pergunta / Termo)	Verso (Resposta / Explicação)
basic	Which seven standard amino acids have nonpolar, aliphatic side chains?	Glycine (Gly, G), Alanine (Ala, A), Valine (Val, V), Leucine (Leu, L), Isoleucine (Ile, I), Methionine (Met, M), and Proline (Pro, P). Glycine is achiral; Proline has a cyclic pyrrolidine side chain that disrupts alpha-helices.
basic	Which three amino acids have aromatic side chains and which absorbs UV light most strongly at 280 nm?	Phenylalanine (Phe, F), Tyrosine (Tyr, Y), and Tryptophan (Trp, W). Tryptophan absorbs UV light most strongly at 280 nm due to its bicyclic indole ring, followed by tyrosine.
basic	What are the structural distinctions between eukaryotic and prokaryotic ribosomes?	• Eukaryotes: 80S ribosomes composed of 60S (large) and 40S (small) subunits. • Prokaryotes: 70S ribosomes composed of 50S (large) and 30S (small) subunits. This difference enables antibiotics (e.g., aminoglycosides, tetracyclines) to target bacterial translation selectively.
basic	How does cholesterol modulate cell membrane fluidity at high versus low temperatures?	Cholesterol is a bidirectional fluidity buffer: • At HIGH temperatures: Restricts phospholipid movement, increasing membrane rigidity and reducing permeability. • At LOW temperatures: Prevents fatty acid chains from packing tightly, preventing crystallization and increasing fluidity.
intermediate	What is the Gibbs Free Energy equation and what determines thermodynamic spontaneity?	Delta G = Delta H - T * Delta S. • Delta G < 0: Spontaneous (exergonic). • Delta G = 0: System at chemical equilibrium. • Delta G > 0: Non-spontaneous (endergonic). Temperature T must be in Kelvin.
intermediate	What mathematical equation links standard free energy Delta G° to the equilibrium constant Keq?	Delta G° = -R * T * ln(Keq). If Keq > 1, Delta G° is negative (products favored at equilibrium); if Keq < 1, Delta G° is positive (reactants favored at equilibrium).
intermediate	What are the four Kinematic Equations for motion with constant acceleration?	1. v = v0 + a * t 2. Delta x = v0 * t + 0.5 * a * t^2 3. v^2 = v0^2 + 2 * a * Delta x 4. Delta x = [(v0 + v) / 2] * t.
intermediate	What are the horizontal and vertical velocity components in projectile motion (neglecting air resistance)?	• Horizontal: vx = v0 * cos(theta) (constant; ax = 0). • Vertical: vy = v0 * sin(theta) - g * t (ay = -g). At the maximum height of trajectory, vy = 0.
advanced	What are Piaget's 4 Stages of Cognitive Development and their key developmental milestones?	1. Sensorimotor (0-2 yrs): Object permanence, circular reactions, stranger anxiety. 2. Preoperational (2-7 yrs): Egocentrism, symbolic play, centration, lack of conservation. 3. Concrete Operational (7-11 yrs): Conservation mastered, mathematical operations, logical thinking with concrete objects. 4. Formal Operational (12+ yrs): Abstract logic, hypothetical-deductive reasoning.
advanced	What are Erikson's 8 Psychosocial Stages and their developmental crises?	1. Trust vs. Mistrust (0-1 yr) 2. Autonomy vs. Shame/Doubt (1-3 yrs) 3. Initiative vs. Guilt (3-6 yrs) 4. Industry vs. Inferiority (6-12 yrs) 5. Identity vs. Role Confusion (12-18 yrs) 6. Intimacy vs. Isolation (18-40 yrs) 7. Generativity vs. Stagnation (40-65 yrs) 8. Integrity vs. Despair (65+ yrs).
advanced	What are the molecular principles and separation criteria of SDS-PAGE electrophoresis?	Sodium dodecyl sulfate (SDS) denatures proteins and coats them with a uniform negative charge (~1 SDS molecule per 2 amino acids), masking native charges and rendering the charge-to-mass ratio uniform. Migration through the polyacrylamide gel matrix toward the positive anode separates proteins SOLELY based on molecular weight (smaller proteins migrate faster and further).
advanced	What is the difference between Reducing and Non-Reducing SDS-PAGE?	• Reducing SDS-PAGE: Includes a reducing agent (beta-mercaptoethanol or DTT) that cleaves covalent disulfide bonds (-S-S-), breaking multimeric complexes joined by disulfides into individual monomeric subunits. • Non-Reducing SDS-PAGE: Retains disulfide bonds intact; multimeric disulfide-linked complexes run as single intact bands.
