Cellular Respiration

· 47:12 · 6 sections
§ 01

Overview

  • Cellular respiration converts nutrients into ATP, the cell's usable energy currency.
  • Three major phases: glycolysis, the citric acid cycle, and oxidative phosphorylation.
§ 02

The Mitochondrion

  • Double-membrane organelle; site of the citric-acid cycle and the electron transport chain.
  • Contains its own circular DNA — evidence of its bacterial ancestry (endosymbiotic theory).
§ 03

Oxidative Phosphorylation

  • Electrons from NADH and FADH₂ move through the ETC, pumping H⁺ into the intermembrane space.
  • ATP synthase uses the H⁺ gradient to phosphorylate ADP → ATP. Net yield ≈ 32 ATP per glucose.

    The learning method that actually works.

    Skip rereading. Use the generated flashcards and practice exam to test yourself — the retrieval-practice effect that cognitive-science research (Roediger & Karpicke, 2006) has shown outperforms passive review for long-term retention.

    • Cards with spaced review
