Here are 8 reputable websites that are NOT .com and that cover photosynthesis and cellular respiration — with brief notes on what each site discusses about those topics and what type/level of resources they provide.

1) Khan Academy — khanacademy.org
- What they cover: Step-by-step lessons and videos on photosynthesis (light reactions, Calvin cycle, pigments, ETC in chloroplasts) and cellular respiration (glycolysis, pyruvate oxidation, Krebs/Citric Acid Cycle, oxidative phosphorylation, chemiosmosis, anaerobic pathways).
- Level & resources: Introductory to AP/undergrad-level; short videos, text explanations, diagrams, practice questions.

2) Wikipedia — wikipedia.org (search “Photosynthesis” and “Cellular respiration”)
- What they cover: Comprehensive overviews including mechanisms (light-dependent reactions, photophosphorylation, Calvin cycle; glycolysis, TCA cycle, electron transport chain), variants (C3/C4/CAM, fermentation), history, biochemistry, and references to primary literature.
- Level & resources: Varies from general to advanced; detailed articles, diagrams, citations to original sources.

3) OpenStax — openstax.org (Biology textbook chapters)
- What they cover: Textbook-style chapters that explain light reactions and the Calvin cycle, overall equation for photosynthesis, and cellular respiration chapters covering glycolysis, Krebs cycle, and oxidative phosphorylation with worked examples and summary questions.
- Level & resources: High-school to undergraduate; free full-text textbook chapters, figures, end-of-chapter review questions.

4) HHMI BioInteractive — biointeractive.org
- What they cover: Interactive animations and videos showing the molecular events of photosynthesis and cellular respiration (e.g., electron flow, chemiosmosis), classroom activities and teacher guides that explore energy flow in cells.
- Level & resources: Secondary school to undergraduate; multimedia animations, classroom-ready activities, short videos, assessments.

5) MIT OpenCourseWare — ocw.mit.edu
- What they cover: Lecture notes, problem sets, and sometimes video lectures from MIT courses that include bioenergetics, photosynthesis, and cellular respiration (mechanistic and biochemical detail; sometimes integrated into broader biochemistry or biology courses).
- Level & resources: Undergraduate to graduate-level; lecture notes, assignments, exams.

6) NCBI Bookshelf — ncbi.nlm.nih.gov/books
- What they cover: Full textbook chapters (e.g., from “Lehninger,” “Molecular Biology of the Cell,” physiology texts) with in-depth biochemical descriptions of photosynthetic mechanisms, electron transport, ATP synthesis, and detailed coverage of cellular respiration pathways and regulation.
- Level & resources: Advanced/graduate-level reference; searchable textbook chapters and figures with citations.

7) BBC Bitesize — bbc.co.uk/bitesize
- What they cover: Clear, curriculum-aligned explanations of photosynthesis (chloroplast structure, limiting factors, uses of glucose) and respiration (aerobic vs anaerobic, fermentation), plus short videos, quizzes and revision notes for UK exams.
- Level & resources: Middle/secondary school; concise summaries, animations, self-check quizzes.

8) S-cool (Revision World) — s-cool.co.uk
- What they cover: Revision notes on photosynthesis (light and dark reactions, factors affecting rate, graphs) and cellular respiration (glycolysis, Krebs, electron transport, ATP yield), plus exam-style questions and model answers.
- Level & resources: GCSE/A-level; revision-focused text, diagrams, practice questions.

If you want, I can:
- Provide direct links to the exact pages on any of these sites,
- Extract or summarize a specific subsection (e.g., the Calvin cycle or oxidative phosphorylation) from one or more of them,
- Or suggest which ones are best for beginner vs. advanced study. Which would you prefer?
