  1. Free energy, photosynthesis, and cellular respiration

    A student is studying the diagram in Figure 1 and notices that the reactions and cellular intermediates of photosynthesis and cellular respiration differ considerably.

  2. An introduction to cellular respiration (article) | Khan Academy

    Photosynthesis and cellular respiration are essential biological processes that rely upon one another. The products of photosynthesis are used by organisms during cellular respiration.

  3. Intro to photosynthesis (article) | Khan Academy

    Jul 17, 2016 · At the level of the overall reactions, photosynthesis and cellular respiration are near-opposite processes. They differ only in the form of energy absorbed or released, as shown in the …

  4. Photosynthesis and cellular respiration | Khan Academy

    In this hands-on activity, students will examine variation in leaf traits across plant species and explore how leaf form relates to the environment and photosynthesis.

  5. Photosynthesis review (article) | Khan Academy

    Photosynthesis uses carbon dioxide and water to make oxygen and high energy sugars like glucose. Respiration takes in oxygen and glucose and turns it back into carbon dioxide and water.

  6. The carbon cycle (article) | Khan Academy

    This simplified diagram of the carbon cycle shows how processes such as photosynthesis, cellular respiration, decomposition, and fossil fuel combustion move carbon between inorganic and organic …

  7. Steps of cellular respiration | Biology (article) | Khan Academy

    Luckily, cellular respiration is not so scary once you get to know it. Let's start by looking at cellular respiration at a high level, walking through the four major stages and tracing how they connect up to …

  8. Introduction to cellular respiration and redox - Khan Academy

    This is a simplified diagram that is designed to help us get a feel for how oxidative phosphorylation works. In a real mitochondrion, the matrix would be much a much larger space than it appears here, …

  9. Overview of metabolism (article) | Khan Academy

    Photosynthesis, which builds sugars out of smaller molecules, is a "building up," or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a "breaking down," or …

  10. Introduction to cellular respiration and redox - Khan Academy

    In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The …
