Question

the third phase of cellular respiration requires energy and converts adp into atp, producing energy. what do we call this phase? krebs cycle the electron transport chain

Explanation:

Cellular respiration has three main phases: glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain. The Electron Transport Chain is the third phase, where energy is used to convert ADP to ATP (oxidative phosphorylation occurs here, producing a large amount of ATP). The Krebs Cycle is the second phase, focusing on generating electron carriers. So the phase described (third phase, converting ADP to ATP, using energy) is the Electron Transport Chain.

Answer:

The Electron Transport Chain
