Glycolysis
The process that uses NADH and FADH to create ATP is oxidative phosphorylation. This process occurs in the inner mitochondrial membrane and involves the transfer of electrons from NADH and FADH to the electron transport chain, leading to the production of ATP through a series of redox reactions.
The proteins involved in the chain, complete with ATP synthase in the end for oxidative phosphorylation, some electron carriers like NADH and FADH2, and the final electron acceptors such as O2.
Aerobic respiration produces 36 ATP from one glucose molecules. Anaerobic respiration produces only 2. Two glucose molecules are produced during glycolysis. In addition to producing ATP from ADP, glycolysis also converts NAD+ to NADH. If no oxygen is available, more energy needs to be produced from glycolysis. However, for glycolysis to occur, NAD+ must be regenerated from NADH. Thus, in a process known as anaerobic fermentation, NAD+ is regenerated from NADH. Fermentation doe snot fully oxydize glucose. After glycolysis, the glucose molecule has been converted into two molecules of pyruvate. Fermentation uses pyruvate to convert NAD+ back to NADH so it can be used for another round of glycolysis. If oxygen is present, the two pyruvate molecules from glycolysis can be fully oxydized in a process known as aerobic respiration. This process consists of the citric acid cycle and the electron transport chain. The process is beyond the scope of this post, but aerobic respiration basically produces more NADH and FADH2 from pyruvate and uses the NADH/FADH2 molecules to oxydize O2 to H2O. The Krebs cycle produces 2 ATP and the electron transport chain produces 32 ATP. Thus, aerobic respiration is a far more efficient means of energy production.
Photosynthesis is the chemical process that uses light to process carbon dioxide in plants.

Energy is transferred from NADH and FADH2 to ATP during cellular respiration in the mitochondria. The electron transport chain uses the energy from these molecules to pump protons across the inner mitochondrial membrane, creating a proton gradient. This gradient drives the production of ATP through the process of oxidative phosphorylation.

Glycolysis produces 4 ATP's and 2 NADH, but uses 2 ATP's in the process for a net of 2 ATP and 2 NADH
Within the context of cellular respiration (as well as in photosynthesis) NADH acts as an electron receptor. During glycolysis and the Kreb's cycle, various molecules are oxidized (lose electrons) and these electrons are passed to NADH. The NADH then carries the electrons to the mitochondria where they are deposited for the electron transport chain which uses the movement of the electrons to generate ATP (adenosine triphosphate; the body's energy molecule).
Glucose metabolism begins with glycolysis and then proceeds to either the TCA (Krebs) cycle or fermentation. Glycolysis and fermentation are both anaerobic processes (they do not use oxygen) and use substrate level phosphorylation to produce ATP (e.g. energy), while the TCA cycle is aerobic (requires oxygen) and uses oxidative phosphorylation to produce ATP. Substrate level phosphorylation produces much less ATP than oxidative phosphorylation.
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.

NADH and FADH2 are electron carriers (they store energy in the form of energetic electrons) and pass these electrons to the electron transport chain, which uses a series of redox reactions driven by the energetic electrons to pump protons across the inner mitochondrial membrane. The protons re-enter the mitochondrial matrix via ATP synthases, leading to the production of ATP - the energy currency of the cell.
Bacteria. It uses the process called chemosynthesis to produce glucose.
