Question

Glucose and ____________ metabolism is crucial to the body. Anabolic reactions include ____________ and gluconeogensis. In gluconeogensis, glucose is synthesized from ____________ and amino acids. Glycolysis and glycogenolysis are ____________ reactions. In glycolysis, glucose is split into two molecules of ____________ to prepare for other processes. Pyruvate can be used for anaerobic ____________ or aerobic respiration

Answer 1

Answer: 1. Glycogen

2. Glycogenesis

3. Fatty acids

4. Catabolic reactions

5. Pyruvate

6. Fermentation

Explanation:

1. Glucose and glycogen metabolism are the primary source of ATP through glycolysis, which provides Acetyl co A needed for further generation of ATP in citric acid cycle.

2. Glycogenesis is an anabolic reaction which involves the building of glycogen chain from glucose units. Anabolic reactions involve the building of macromolecules from smaller building blocks.

3. Gluconeogenesis involves the synthesis of glucose from non glucose precursors like amino acids from protein and fatty acids from lipids.

4. Catabolic reactions involve the breakdown of macromolecules into simpler and smaller building blocks.

5. Pyruvate is the last product in glycolysis where phosphoenol pyruvate is converted to Pyruvate by the enzyme, pyruvate kinase.

6. Private has two fates; aerobic respiration and anaerobic fermentation. In anaerobic fermentation, pyruvate is either reduced to lactate through lactic acid fermentation or converted to ethanol and water in low oxygen conditions.
