- Enzymes act by reducing the activation energy of areaction. Describe several ways in which this isaccomplished.1A. Produceadiagramtoillustratethedifferenttypesofmoleculesfoundincells.Briefly describe their properties and functions within the cell. In a separate diagram, describe how carbohydrates, amino acids and triacylglycerides interact metabolically in the generation of energy in the form of ATP.B. Mineralsandvitaminsareimportantnutritionalmoleculesbecausetheyfunctionas cofactors for critical enzymes in living systems. Without them, important biochemical reactions required for growth and tissue repair will not occur. Knowing this, explain the biochemical significance of folate and iron supplementation in pregnant women and women of reproductive age. Consider the effects of folate and iron deficiency as well. 2A. Thevalueofenzymesinlivingsystemsisthatwithoutthem,chemicalreactionsrequired for life to exist would not be possible under physiological conditions. On the basis of this, discuss how enzymes make life possible from a biochemical perspective.

Another cat, Griselda, isgiven only dry cat food by her far less indulgent owner. Canned tunais essentially all protein, whereas dry cat food can be considered 70%carbohydrate and 30% protein. Assuming that these animals haveno other sources of food, what can you say about the differences andsimilarities in their catabolic activities?
