As reducing agents NADH and FADH2, with NADH holding the majority

After the energy from sunlight, glucose is probably the most important molecule on earth. In photosynthesis, energy from sunlight is converted into chemical energy stored in the chemical bonds of glucose. But sunlight remains the ultimate source of energy for almost all species on the earth.
Energy
Sugar is the most readily form of energy to be used by the body.
Food or glucose
By light, ATP is produced (ATP is the most basic form of usable energy in organisms). Further, during "dark phase", CO2 is incorporated into carbohydrates, thus forming glucose.

Glucose oxydation
Cellular Respiration is the process in which a Cell turns Glucose into ATP. Both glucose and oils are fed into the Kreb's citric acid cycle - one CH2 'monomer' at a time - and Atp is prodigiously produced. So the basic Answer is that the Cell turns glucose into biochemically usable energy.
Two thirds of it
The process of the breakdown of glucose to release energy happens in two different ways. One of them is called the citric cycle and yeilds the largest amount of energy, and the other is the lactic acid cycle which works when the oxygen supply is low.
The glucose molecule is required for aerobic conditions. Glucose is broken down into molecules that along with oxygen enter the citric acid cycle. This produces energy during aerobic conditions.
The whole point of cellular respiration is to harness energy from the original source, glucose, and transform it into a usable and stable source, ATP.
This process is called glycolysis. It is also called the citric acid cycle or the Krebs's cycle.
Glucose is broken down in several steps of cellular respiration. The three main steps in cellular respiration are, in chronological order, Glycolysis, Oxidative decarboxylation of pyruvate, and the Krebs Cycle (aka The Citric Acid Cycle). Each of these processes further break down glucose and extracts the energy from the bonds. That energy is then converted and used to make ATP. ATP which is the main energy molecule used by cells.
No. Citric acid is matter. Energy is that which allows change in matter in the form of heat and movement.

Respiration, also called cellular respiration, is the process when animal/plant cells break down glucose to release its energy. Respiration occurs in two stages: (1) Glycolysis, (2) Krebs Cycle/ citric acid cycle. Stage 1, glycolysis, occurs in the cytoplasm, when glucose is broken down a little, and 2 ATP (energy storages) are made. Stage 2, the Krebs Cycle/ citric acid cycle, occurs in the mitochondria of a cell, when the glucose molecules are really broken down; a large amount of energy is released, in the form of 34 ATP! Added together, the net total of ATP is 34. The cell will later use this energy to help the organism function.
