- Enzymes can be classified by the types of reactions they do (as per chapter 21). From the metabolism reactions we looked at, an example of an isomerization enzyme is _________________________. An example of a ligase enzyme is _____________________. An example of an oxidoreductase enzyme is _____________________________. An example of a transferase enzyme is _________________.arrow_forwardWhen you eat starchy foods resulting in a breakdown to give glucose to the body, you have induced a(n): Group of answer choices ion combustion oxidation-reduction reaction oxygen combustion Ion-reduction reactionarrow_forward“Enzyme increases the rate of a reaction by lowering the activation energy. In doing so, it also changes the equilibrium of that reaction.” Do you agree/disagree with this statement? And why?arrow_forward
- Assume you have a solution of reactions with an enzyme. You decided to apply heat to further “increase” the rate of reaction. However, after heating, you observed that the rate of reaction decreased, the enzymes’ activity decreased, which is the opposite of what you have expected. Explain what happened. Discuss what happens when the solution contains a high concentration of substrates.arrow_forwardthis one represents an endothermic reaction. Things are similar: the flat line on the left (beginning of the reaction) is the total energy possessed by the reactant molecules; once again, kJ stands for energy in kiloJoules, thousands of Joules. The flat line on the right (reaction complete) is the total energy of the products. Since an endothermic reaction has a net absorption of energy (taking this extra energy from the surroundings), the products have higher energy than the reactants. Question: the energy of the reactant molecules is kJ. [to answer, simply identify the correct y-axis coordinate.] 250 200 PE (kJ) 150 100 50 Reaction pathwayarrow_forwardExplain why enzymes are considered “biological catalysts” Use the following terms in the explanation: activation energy, lock and key model, substrate specificityarrow_forward
- What is a key characteristic of exergonic reactions? They consume energy. They require glucose fusion. Their products have more energy than the reactants. They release energy that can be used by cells. They involve the formation of bonds.arrow_forwardDefine the following terms: a. hydride ion b. oxidation reaction c. energy d. FAD e. electron transport pathwayarrow_forwardEnzymes are biological catalysts that decrease the activation energy necessary for a chemical reaction to occur. Can enzyme that do not use cofactor (molecule other than protein) catalyze a redox reaction? Yes or noarrow_forward
- The movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy --------> C6H12O6 + 6O2 C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energyarrow_forwardAs a researcher you wish to know how well your newly discovered enzyme works compared to other known enzymes. which catalytic parameters will determine and why?arrow_forwardIs the following process considered oxidation or reduction? a oxidation b reduction Fe²+ Feºarrow_forward
