1. Carbohydrates, lipids, and proteins are important biomolecules. Describe the structures and properties of carbohydrates, lipids, and proteins including the different forms of these biomolecules that are present within the body.
2. The membrane of a cell is an important structure that isolates the cell's cytosol from the external environment. The components of membranes are important determinants of their function. What are the components of a membrane and how do those components function?
3. Summarize the process whereby energy is obtained by glucose oxidation. (Please note- you could make this a very long answer, but just focus on the shortened/abbreviated steps).
Structures and Properties of Carbohydrates:
Carbohydrates can be viewed as hydrates of carbon also referred to as 'sugars or saccharides'. It is one of the most abundant biomolecules that is inclusive of nucleic acids, fats and proteins. The basic carbohydrate unit is termed as monosaccharide that holds a general formula of (C H20) n. The representation structures of the carbohydrates are; hemi-acetal structure, open chain structure and Haworth structure. The hemi-acetal structure is a property of the carbohydrates found in the glucose element and is condensed with the OH group of the carbon molecule. The open chain structure is a long straight chain that is in the carbohydrate. The Haworth structure of the carbohydrate is found in the pyranose rings. The other property of the carbohydrate is the stereoisomerism which holds the same formula in structure. The chemical properties are; hydrolysis, oxidation and the ozazone formation with phenlyhydrazine. The biological properties are inclusive of; energy ...
The solution discusses glucose oxidation. The proteins including the different forms of the biomolecules which are present within the body are determined,
Comparing Efficiency of Glucose Oxidation
Compare the relative efficiencies (in ATP's per mole of glucose oxidized) of glucose oxidation via glycolysis + the citric acid cycle vs. glucose oxidation via the pentose phosphate pathway + gluconeogenesis. Assume that NADH and NADPH are each energetically equivalent to three ATP's.View Full Posting Details
