Textbook Question

Add labels to the figure that follows, which illustrates the breakdown of a disaccharide inside a cell.

Verified step by step guidance

Identify the disaccharide structure at the top of the image, which consists of two hexagonal rings representing monosaccharides linked together.

Recognize the arrow pointing from the disaccharide to the green structure, indicating the process of breakdown or hydrolysis.

Label the disaccharide structure as 'Disaccharide' or 'Substrate', which is the molecule being broken down.

Label the green structure as 'Enzyme', which facilitates the breakdown of the disaccharide into monosaccharides.

Label the resulting monosaccharides after the breakdown, which are the products of the enzymatic reaction.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Disaccharides

Disaccharides are carbohydrates formed by the combination of two monosaccharides through a glycosidic bond. Common examples include sucrose (glucose + fructose) and lactose (glucose + galactose). Understanding their structure and function is crucial for analyzing how they are broken down in cellular processes.

Glycosidic Bond

A glycosidic bond is a type of covalent bond that links monosaccharides together to form disaccharides and polysaccharides. This bond is formed through a dehydration reaction, where a water molecule is released. Recognizing how these bonds are formed and broken is essential for understanding carbohydrate metabolism.

Cellular Metabolism

Cellular metabolism encompasses all biochemical reactions occurring within a cell, including the breakdown of carbohydrates like disaccharides. This process involves enzymes that catalyze the hydrolysis of glycosidic bonds, releasing energy and simpler sugars for cellular use. A grasp of metabolic pathways is vital for comprehending how cells utilize nutrients.
