Metabolic Pathways of Biomolecules

Front

What is metabolism?

Back

Metabolism is the bulk of chemical reactions of biomolecules themselves, involving the processing of carbohydrates, fats, and proteins in various ways.

Front

What are the two main types of metabolic processes?

Back

Catabolism (breaking down large molecules to release energy) and Anabolism (building larger molecules from smaller ones, requiring energy).

Front

What is a metabolic pathway?

Back

A series of consecutive biochemical reactions used to convert a starting material into an end product.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells have no nucleus and contain a single circular DNA molecule, while eukaryotic cells have DNA in a membrane-enclosed nucleus and are compartmentalized into organelles.

Front

What is the function of mitochondria?

Back

Mitochondria generate most of the energy needed for the cell.

Front

What are the main types of adenosine phosphates involved in metabolism?

Back

Monophosphate (AMP), Diphosphate (ADP), Triphosphate (ATP), and Cyclic Monophosphate (cAMP).

Front

What is the role of ATP in cellular reactions?

Back

ATP functions as both a source of a phosphate group and a source of energy.

Front

What is the significance of coenzyme A in metabolism?

Back

Coenzyme A, a derivative of Vitamin B, is crucial for the synthesis and oxidation of fatty acids and the metabolism of carbohydrates.

Front

What is glycolysis?

Back

Glycolysis is the first stage of glucose metabolism, involving the breakdown of glucose into pyruvate, producing ATP.

Front

What are the end products of carbohydrate digestion?

Back

Glucose and monosaccharides from carbohydrates, amino acids from proteins, and fatty acids and glycerol from fats.
