Assessment Strategies

 After the completion of this course, students will be able to-

CO164-discuss the properties and functions of enzymes and outline mechanisms of enzyme catalyzed reactions.

CO165-describe major pathways of carbohydrate metabolism.

CO166-recognize the structures of amino acids and elucidate common pathways of amino acid catabolism.

CO167-summarize the functions of proteins and identify the influence of the three-dimensional shape and subunits of a protein on its function.

CO168-analyse the role of fat in energy production, membrane synthesis, and production of bioactive molecules and describe the structure, biosynthesis, oxidation and storage of fatty acids.

CO169-learn the structure and functions of  RNA and DNA.

CO170-correlate how the biomolecules such as proteins, carbohydrates, lipids, nucleic acids are made from the simple precursors.

CO171-interpret the structure-function relationships of the proteins, carbohydrates, lipids, and nucleic acids.
