Cheat Sheet
- Michaelis-Menten Kinetics -
Understanding the relationship between reaction rate and substrate concentration is crucial for enzyme function, as described in Lehninger Principles of Biochemistry. The equation v = Vmax[S]/(Km + [S]) models this behavior, where Km is the substrate concentration at half Vmax. Remember the mnemonic "KMatches Substrate" to recall that Km reflects affinity for the substrate.
- Glycolysis Rate-Limiting Steps -
Hexokinase, phosphofructokinase-1 (PFK-1), and pyruvate kinase control the flux through glycolysis according to Harvard Medical School resources. PFK-1 is allosterically activated by AMP and inhibited by ATP and citrate, ensuring energy balance. Reviewing these regulatory points helps predict how cells adjust to energy demands.
- Henderson-Hasselbalch Equation -
The formula pH = pKa + log([A - ]/[HA]) explains buffer behavior in physiological systems, as outlined by the NCBI Bookshelf. Practicing calculations with phosphate or bicarbonate buffers makes acid - base balance intuitive. This equation is key for predicting pH changes in metabolic pathways and experimental assays.
- Citric Acid Cycle Energy Yield -
Each turn of the cycle oxidizes one acetyl-CoA to produce 3 NADH, 1 FADH2, and 1 GTP, based on IUBMB data. Converting these to ATP yields (~2.5 ATP per NADH and ~1.5 ATP per FADH2) gives about 10 ATP per acetyl-CoA. Visualizing the cycle as an energy factory helps solidify how cells harvest reducing equivalents.
- Amino Acid Essentiality Mnemonic -
Use "PVT TIM HALL" (Phenylalanine, Valine, Threonine, Tryptophan, Isoleucine, Methionine, Histidine, Arginine, Leucine, Lysine) from the University of Cambridge to recall essential amino acids. Categorizing them by side-chain properties (hydrophobic, polar, charged) aids in predicting protein structure and function. This shortcut is a go-to for metabolic and nutrition questions.
