6 FAQs about [This common energy storage molecule breaks down into sugar monomers]

Which molecule is a storage form of glucose?

Glycogen is the storage form of glucose in humans and other vertebrates, and is made up of monomers of glucose. Glycogen is the animal equivalent of starch and is a highly branched molecule usually stored in liver and muscle cells. Whenever glucose levels decrease, glycogen is broken down to release glucose.

How are glucose monomers linked in unbranched chains?

In cellulose, glucose monomers are linked in unbranched chains by β 1-4 glycosidic linkages. Because of the way the glucose subunits are joined, every glucose monomer is flipped relative to the next one resulting in a linear, fibrous structure.

What is the structure of branched glucose monomer chains?

Branched glucose monomer chains comprise amylopectin by α 1-4 and α 1-6 glycosidic linkages. Because of the way the subunits are joined, the glucose chains have a helical structure. Glycogen (not shown) is similar in structure to amylopectin but more highly branched.

How is cellulose made up of glucose monomers?

Cellulose is made up of glucose monomers that are linked by bonds between particular carbon atoms in the glucose molecule. Every other glucose monomer in cellulose is flipped over and packed tightly as extended long chains (see Figure 4). This gives cellulose its rigidity and high tensile strength—which is so important to plant cells.

How is starch broken down?

The starch that is consumed by humans is broken down by enzymes, such as salivary amylases, into smaller molecules, such as maltose and glucose. The cells can then absorb the glucose. Starch is made up of glucose monomers that are joined by α 1-4 or α 1-6 glycosidic bonds.

What molecule breaks down a glucose molecule into two pyruvate molecules?

Glycolysis is the process of breaking down a glucose molecule into two pyruvate molecules, while storing energy released during this process as adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide (NADH). [ 2 ] Nearly all organisms that break down glucose utilize glycolysis. [ 2 ]
