1. Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside‚ how can the candy bar sit still on the shelf in the grocery store? Indeed‚ candy bars have a significant amount of carbohydrates (mostly simple‚ such as sugar) in their composition. The energy stored within these carbohydrates is chemical potential energy‚ and cannot actually be released or converted into usable chemical energy until it is eaten and taken up into the body‚ where various

What Are The Major Components of Biological Membranes And How Do They Contribute To Membrane Function?. Summary. The role of the biological membrane has proved to be vital in countless mechanisms necessary to a cells survival. The phospholipid bilayer performs the simpler functions such as compartmentation‚ protection and osmoregulation. The proteins perform a wider range of functions such as extracellular interactions and metabolic processes. The carbohydrates are found in conjunction
