3.Define oxidation and reduction reactions. 4. For each of the 4 types of biochemical molecules that you studied in A&P 1, chapter 2 describes what their roles in metabolism are. Carbohydrates- body uses carbohydrates to make glucose which is the body’s main energy source. Lipids- metabolized for use as a primary energy source. Proteins- some enzymes help to break down large nutrient molecules Nucleic acids- Nucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base. 5.Which nutrient molecule is the universal energy source and is preferred by nerve cells? 6.List the steps of aerobic respiration using glucose. How many ATP molecules are made at each step? How many total? 7.List the reactants and products for: 8.How is cellular respiration regulated? Name the key enzyme that regulates the rate of glycolysis and explain how it works.
9.Which enzyme makes the majority of ATP in human cells and where specifically is it located? 10.What is the role of oxygen in aerobic respiration? Provide specific details where it is used and what it reacts with.
