Cheat Sheet
- Glycolysis as the Key Entry Point -
All fermentation pathways begin with glycolysis in the cytoplasm, converting one glucose into two pyruvate while netting 2 ATP and 2 NADH. Remember the reaction: Glucose + 2 ADP + 2 Pi → 2 Pyruvate + 2 ATP + 2 NADH + 2 H+, a staple question on any anaerobic respiration quiz. Use the mnemonic "Goodness Gracious, Father Franklin Did Go By Picking Pumpkins" to recall the ten glycolytic enzymes.
- NAD+ Regeneration Ensures Continuity -
During anaerobic fermentation, NADH must be oxidized back to NAD+ for glycolysis to continue: for lactic acid fermentation, pyruvate + NADH → lactate + NAD+. On your fermentation pathways quiz, spot that NAD+ recycling is the core concept ensuring redox balance. Think "re-stock NAD+" to ace metabolic pathway quiz questions.
- Comparing Major Fermentation Types -
Lactic acid, ethanol, and mixed-acid fermentations differ by end products and organisms - e.g., Lactobacillus creates lactate while Saccharomyces yields ethanol and CO₂. For the types of fermentation quiz, memorize: "Ethanol equals Yeast, Lactic equals Lactobacillus." Diagrams from microbiology fermentation test sources like Bergey's Manual clarify key differences.
- ATP Yields: Low But Adaptable -
Anaerobic respiration and fermentation yield far less ATP (2 ATP per glucose) than aerobic respiration (~30 - 32 ATP). Compare this in your metabolic pathway quiz by contrasting substrate-level phosphorylation in glycolysis versus oxidative phosphorylation. A quick trick is "2 versus 32" to remember the energy gap.
- Alternative Electron Acceptors in Anaerobic Respiration -
Beyond fermentation, some bacteria use nitrate (NO₃❻), sulfate (SO₄²❻), or fumarate as terminal electron acceptors in anaerobic respiration, generating more ATP than fermenters. Sample reaction: NO₃❻ + 2 e❻ + 2 H❺ → NO₂❻, a common question in anaerobic respiration quizzes. Recall "NO SO FAUX" to remember nitrate, sulfate, fumarate acceptors.
