During electron transport, energy from _____ is used to pump hydrogen ions into the _____

NADH and FADH2 ... inter-membrane space

The proximate (immediate) source of energy for oxidative phosphorylation is _____.

In glycolysis, ATP molecules are produced by _____.

substrate-level phosphorylation

Which energy-rich molecule produced by cellular respiration directly powers cell work?

Which of these is NOT a product of glycolysis?

FADH2. It is a product of the citric acid cycle.

Which statement describes glycolysis?

This process splits glucose in half and produces 2 ATPs for each glucose.

Which statement describes the electron transport chain?

This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.
