Question

match each metabolic pathway to its description. acetyl coa → fatty acids amino acids → carbon skeletons triglycerides → fatty acids amino acids → proteins glycogen → glucose glucose → pyruvate fatty acids → acetyl coa proteins → amino acids glucose → glycogen amino acids → glucose acetyl coa → ketone bodies fatty acids → triglycerides glycolysis glycogenolysis glycogenesis gluconeogenesis beta - oxidation lipolysis lipogenesis fatty acid synthesis proteolysis protein synthesis deamination ketogenesis

Explanation:

• Glycolysis: This is the metabolic pathway that breaks down glucose into pyruvate. So, “Glucose → Pyruvate” matches glycolysis.
• Glycogenolysis: It is the process of breaking down glycogen into glucose. Thus, “Glycogen → Glucose” corresponds to glycogenolysis.
• Glycogenesis: This is the formation of glycogen from glucose. So, “Glucose → Glycogen” is glycogenesis.
• Gluconeogenesis: It is the synthesis of glucose from non - carbohydrate sources like amino acids. Hence, “Amino acids → Glucose” is gluconeogenesis.
• Beta - oxidation: This is the breakdown of fatty acids to acetyl CoA. So, “Fatty acids → Acetyl CoA” is beta - oxidation.
• Lipolysis: It is the breakdown of triglycerides into fatty acids. Thus, “Triglycerides → Fatty acids” is lipolysis.
• Lipogenesis: This is the synthesis of fatty acids from acetyl CoA. So, “Acetyl CoA → Fatty acids” is lipogenesis.
• Fatty acid synthesis: This is the process of building fatty acids (not from acetyl CoA in the context of lipogenesis here, but if we consider the general term). However, if we assume the given options, there is no other match for the general fatty acid synthesis term in the given left - hand side options. But if we consider the overall metabolism, it's a separate pathway conceptually.
• Proteolysis: This is the breakdown of proteins into amino acids. So, “Proteins → Amino acids” is proteolysis.
• Protein synthesis: It is the formation of proteins from amino acids. Thus, “Amino acids → Proteins” is protein synthesis.
• Deamination: This is the removal of the amino group from amino acids (a step in amino acid metabolism where amino acids are converted to carbon skeletons). So, “Amino acids → Carbon skeletons” is deamination (as part of the process where amino group is removed to form carbon skeletons).
• Ketogenesis: This is the formation of ketone bodies from acetyl CoA. So, “Acetyl CoA → Ketone bodies” is ketogenesis.

Answer:

• Glycolysis: Glucose → Pyruvate
• Glycogenolysis: Glycogen → Glucose
• Glycogenesis: Glucose → Glycogen
• Gluconeogenesis: Amino acids → Glucose
• Beta - oxidation: Fatty acids → Acetyl CoA
• Lipolysis: Triglycerides → Fatty acids
• Lipogenesis: Acetyl CoA → Fatty acids
• Proteolysis: Proteins → Amino acids
• Protein synthesis: Amino acids → Proteins
• Deamination: Amino acids → Carbon skeletons
• Ketogenesis: Acetyl CoA → Ketone bodies
