Photosynthesis:The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. In this process, carbon dioxide and water are converted into glucose.
Gluconeogenesis: The metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates like lactate, glycerol, and glucogenic amino acids.
Glucose:A simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
