Glycogen is more highly branched than amylopectin and amylose. The advantage of glycogen’s highly branched structure is that the multiple ends are where enzymes start to cleave off glucose molecules. As a result, with many ends available, it can provide glucose much more quickly to the body than it could if it was for example a linear molecule like amylose with only two ends.

Why do animals with millions of cells "need" a circulatory system while animals with few cells can do without one?

Animals which consist of few cells have a capacityto transport the nutrients by cell interactions and diffusion. The maximum distance of the last one is around 0.1 mm. So it...

Distinguish between amylose and amylopectin.

Amylose and amylopectin are the structural components of starch molecule.They are made of glucose units.Amylose is formed by straight chains of glucose with alpha 1,4 bonds, while amylopectin is a...

It is the general equation of cellular respiration A) Glucose = CO2 + O2 B) 6CO2 +6 H2O + solar energy = 6O2 + glucose C) Glucose + O2 = CO2 + H2O + energy

C) Glucose + O2 = CO2 + H2O + energy

Why do cells need to use energy? (Why is energy important to cells? What specific things do cells need energy to do?)

Energy is necessary for cells to undergo many biochemical processes. The macroergic ATP molecule plays a particularly important role in all such processes. Great "reservoirs" of energy are molecules of...

Why is it that prokaryotic cells gain more ATPs from glucose as compared to eukaryotic cells?

In prokaryotes, there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is consumed in transporting across the organelle. Therefore, 38 ATPs are made...

what is the structural advantage of glycogen for animals as compared to either amylose or amylopectin?

It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units. It is more highly branched...
