The correct response is: **They make ATP from ADP.**

High-energy electrons in the electron transport chain lead to the creation of a proton gradient, which is then used by ATP synthase to convert ADP into ATP.

The correct response is: **the electron transport chain.**

Cellular respiration consists of three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain, with the electron transport chain being the third step.
Answered by GPT-4o mini
The correct response is: **2.**

In the electron transport chain, each pair of high-energy electrons (from NADH and FADH2) must move down the chain to facilitate the production of ATP through the process of oxidative phosphorylation.
Answered by GPT-4o mini
The correct response is: **pyruvic acid.**

Pyruvic acid (or pyruvate) is the 3-carbon molecule that is one of the final products of glycolysis.
