the metabolic pathway which produces carbohydrate is.
Answers
Answer:
Gluconeogenesis and the pentose phosphate pathway represent the two main anabolic pathways to produce new carbohydrate molecules.
Explanation:
Gluconeogenesis
Gluconeogenesis (GNG) is the construction of new glucose molecules in the body compared to glucose that is broken down from the long-term storage molecule glycogen. It is found mainly in the liver, but small amounts are also found in the small intestine and kidneys. Gluconeogenesis is the reversal of glycolysis, which breaks down glucose molecules into their subcomponents.
Because gluconeogenesis requires energy, it is also known as the "endogenous glucose pathway". When small precursor molecules combine, a high-energy product such as glucose is produced. Gluconeogenesis is an essential cycle that produces glucose, which is used for all catabolic functions and to sustain life.
The pentose phosphate pathway
The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt and the HMP shunt) is a parallel metabolic pathway with glycolysis. It produces NADPH and pentoses (5-carbon sugars) and ribose-5-phosphate. synthesis of nucleotides. Although the pentose phosphate pathway involves the oxidation of glucose, its primary role is anabolic rather than catabolic. This pathway is particularly important for red blood cells (erythrocytes). The route has two separate stages. The first is an oxidative step that produces NADPH, and the second is a non-oxidative synthesis of 5-carbon sugars. In most organisms, the pentose phosphate pathway occurs in the cytosol; in plants, most steps occur in plastids.

Answer:The metabolic pathway that produces carbohydrates is called photosynthesis.
Explanation: This process takes place in plants and certain other organisms, and involves the conversion of carbon dioxide and water into glucose (a simple sugar) and oxygen, using light energy from the sun.
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
It would be impossible to overestimate the importance of photosynthesis in the maintenance of life on Earth. If photosynthesis ceased, there would soon be little food or other organic matter on Earth. Most organisms would disappear, and in time Earth’s atmosphere would become nearly devoid of gaseous oxygen. The only organisms able to exist under such conditions would be the chemosynthetic bacteria, which can utilize the chemical energy of certain inorganic compounds and thus are not dependent on the conversion of light energy.
Energy produced by photosynthesis carried out by plants millions of years ago is responsible for the fossil fuels (i.e., coal, oil, and gas) that power industrial society. In past ages, green plants and small organisms that fed on plants increased faster than they were consumed, and their remains were deposited in Earth’s crust by sedimentation and other geological processes. There, protected from oxidation, these organic remains were slowly converted to fossil fuels. These fuels not only provide much of the energy used in factories, homes, and transportation but also serve as the raw material for plastics and other synthetic products.
