In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
In this highly animated and colorful object, learners examine the steps of carbohydrate digestion. A brief quiz completes the activity.
Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.
In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
