electron carrier
An electron carrier is a molecule that transports tiny particles called electrons within cells during energy production. These carriers, such as NADH and FADHâ‚‚, pick up electrons from food molecules and transfer them to other parts of the cell. This process helps generate energy in the form of ATP, which powers various cellular functions. Think of electron carriers as shuttles that move electrons efficiently, ensuring the cell can produce energy smoothly and sustain its activities.
