GED® Science: Cellular Energy (Deep Dive)
A deep dive into how living things get, store, and use energy, expanding the single 'Cellular Energy' lesson from the GED® Life Science course into a full mini-course. You'll meet ATP (the cell's energy currency), follow photosynthesis as it captures sunlight into sugar and cellular respiration as it releases that energy, see how the two processes form a cycle, learn how cells make energy without oxygen (fermentation), and practice reading energy data. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
📚 Course Curriculum
Every living thing needs energy — to grow, move materials, build molecules, repair damage, and stay warm. But cells can't plug into a wall outlet. …
Open trial session →Photosynthesis is how plants, algae, and some bacteria capture light energy and store it as chemical energy in sugar. In plants it happens mainly in …
Open trial session →Storing energy in sugar is only half the story. To actually use that energy, cells run cellular respiration, which breaks glucose back down and captures …

Photosynthesis and cellular respiration aren't separate facts to memorize — they're two halves of a single energy and matter cycle. Look closely and you'll see …
Open trial session →Aerobic respiration needs oxygen and produces a lot of ATP. But what happens when oxygen runs low? Some cells can still make a small amount …
