Glucose + Oxygen = Carbon Dioxide + Water + Energy

is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. This process is known as and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also.

Plants cells contain a number of structures that are involved in the process of photosynthesis:

is the chemical process by which green plants convert sunlight into sugar. In essence, this process transforms a wave of light energy into chemical potential energy, which the plant then stores in the molecular bonds of sugar molecules.


The 6 .means that the glucose molecule contains 6 atoms of Carbon.

Figure 3. Aerobic versus Anaerobic Respiration. The process of anaerobic respiration converts glucose into two lactate molecules in the absence of oxygen or within erythrocytes that lack mitochondria. During aerobic respiration, glucose is oxidized into two pyruvate molecules.


How Is Glucose Made in Photosynthesis

The pyruvate molecules generated during glycolysis are transported across the mitochondrial membrane into the inner mitochondrial matrix, where they are metabolized by enzymes in a pathway called the Krebs cycle (). The Krebs cycle is also commonly called the citric acid cycle or the tricarboxylic acid (TCA) cycle. During the Krebs cycle, high-energy molecules, including ATP, NADH, and FADH2, are created. NADH and FADH2 then pass electrons through the electron transport chain in the mitochondria to generate more ATP molecules.

The Mitochondria C C C C C C The Glucose molecule enters the mitochondria for cellular respiration, but before anything else can happen, the molecule must go through Glycolysis, which is the breakdown of Glucose, because it's too big of a molecule.

Figure 4. Krebs Cycle. During the Krebs cycle, each pyruvate that is generated by glycolysis is converted into a two-carbon acetyl CoA molecule. The acetyl CoA is systematically processed through the cycle and produces high-energy NADH, FADH2, and ATP molecules.
