FOCUS ON EVOLUTION
A recent revival of the antievolutionary “intelligent design” argument holds that biochemical pathways are too complex to have evolved, because all intermediate steps in a given pathway must be present to produce the final product. Critique this argument. How could you use the diversity of

- 1. Carbon dioxide +Water+ Energy → Sugar + Oxygen 2. Sugar + Oxygen → Water + Carbon Dioxide + Energy the second reaction shown here (cellular respiration), which of these descriptions compares the products and reactants The process produces ADP as a product, which has a lower energy level compared to the reactants. The process produces inorganic molecules only, which have a lower energy level compared to the products. The process produces ATP as a product, which provides a greater cellular energy compared to the reactants. The process produces heat energy as a byproduct, which causes the reactants to be less energetic compared to the products.

They can be anabolic or catabolic They can be both energy-releasing (exergonic) and energy-requiring (endergonic) They are often made up of a series of chemical reactions They often have multiple different enzymes working in the same pathway Each metabolic pathway is entirely separate and does not interact or connect at all with other metabolic pathwaysarrow_forwardMany enzymes help in cellular respiration. Using the figure to the right, explain the difference between this reaction with and without an enzyme. You must use the following terms in your answer; active site, induced fit, substrate and activation 1. Enzyme Action Without enzyme Activation energy without enzyme energy.

- Would you describe metabolic pathways as inherently wasteful or inherently economical, and why?arrow_forwardQ1: Why is it important that enzymes are not permanently altered when they bind with substrate molecules? Q2: How would a higher temperature or higher salt concentration make it more difficult for an enzyme to function effectively? Q3: If a cell was unable to produce a particular enzyme necessary for a metabolic pathway, describe how the absence of that enzyme would affect the cell.arrow_forwardEnzymes are catalysts that greatly increase the rates of biochemical reactions. They convert substrate molecules (S) to product molecules (P) in the reaction SP by functioning in which way? O increase the free energy of the subutrate meilecuiles increase the free energy of activation of the reaction O decrease the free energy of activation for the reaction O increase the free energy released by the reactionarrow_forward
