Question

These molecules then bring the _________ generated by glycolysis and the Krebs cycle to the ___________ embedded in the bacterial cell __________ membrane.

Answer 1

Molecules generated during glycolysis and the Krebs cycle, such as NADH and FADH2, transport electrons to the electron transport chain in the bacterial cell inner membrane to produce ATP.

Step-by-step explanation:

These molecules then bring the electrons generated by glycolysis and the Krebs cycle to the electron transport chain embedded in the bacterial cell inner membrane.

During glycolysis, glucose is broken down in the cytoplasm, producing pyruvate molecules and energy carriers, including two molecules of NADH per glucose molecule. These pyruvate molecules are then transported into the mitochondrial matrix, where they undergo transformation into acetyl CoA, before entering the Krebs cycle. Also known as the citric acid cycle or tricarboxylic acid cycle, the Krebs cycle generates high-energy molecules such as ATP, NADH, and FADH2. NADH and FADH2 are significant because they carry electrons to the electron transport chain, which is integral in generating a large amount of ATP through the process of oxidative phosphorylation.
