1. T/F Feedback inhibition only acts through enzymes (false and products) 2. T/F In the first reaction of glycolysis, glucose receives a phosphate group from ATP. This reaction is endergonic. (true) 3. T/F Chlorophyll is located in the inner membrane of the chloroplast (false it’s outer membrane) 4. T/F Anabolic reactions are endergonic (true) 5. T/F The utilization of “food” in the mitochondria, with the associated formation of ATP, is termed cellular respiration (true) 6. T/F A prokaryotic cell does not have a nucleus, whereas a eukaryotic cell does. (true) 7. T/F Plants undergo cellular respiration (true) 8. T/F A symport is a type of cotransporter (true) 9. T/F A lysosome is a membrane bound sac that transports substances in cells (false vesicles) 10. T/F Ribosomes are found in the rough endoplasmic reticulum. (true) 11. T/F The interior of the phospholipid bilayer is charged. (false, not charged) 12. T/F An enzyme slightly changes shape when it binds to a substrate. (true) 13. An example of a uniport is a proton pump (true) 14. T/F Proteins are modified and packaged in the golgi apparatus (true) 15. T/F Enzymes lower the activation energy. (true) 16. T/F An enzyme may orient substrates, induce strain, or donate and accept electrons (true) 17. T/F Lysosomes have an acidic interior (true) 18. T/F Most enzymes are much smaller than their substrates. (false, no significant relationship b/w size) 19. T/F The interior of the phospholipid bilayer is aqueous. (false) Life Science 7A Midterm 1 Review Session 20. T/F Positive allosteric regulators stabilize the active form of the enzyme. (true) 21. T/F All enzymes are allosterically regulated. (false) 22. T/F Both the active site and the regulatory site are present on the same subunit. (false) 23. T/F Factors that can either activate or inhibit allosteric enzymes are called regulators (true) 24. T/F K-Cl bond is more likely to form an ionic bond than F-I (true) 25. T/F Cellular respiration creates energy for an animal cell (false energy is not CREATED but CONVERTED from glucose to AT
