Question

Hello I really need help with these BIO-1 questions. Could you guys please answer all of the multiple choice questions. I know it seems like a lot but i would highly appreciate it becuase i really need help on them. Thank you guys! I truly appreciate it.

6. Bond breaking energy and bond formation energy. Fill in the blanks with the appropriate choices in the correct order: A. requires, requires B. requires, releases C. releases, releases D. releases, requires E. none of the above 7. An enzyme increases the rate of a reaction by: A. reducing the free energy change of a reaction B. increasing the free energy change of a reaction C. increasing the activation energy of a reaction D. reducing the activation energy of a reaction 8. Entropy is a measure of disorder. When a living cell creates order within itself in the form of macromolecules such as proteins, polysaccharides, nucleic acids, etc: A. It is increasing entropy within itself B. It is reducing entropy within itself C. It is reducing the entropy of the universe as a whole D. It is increasing entropy within itself as well as increasing the entropy of the universe 9. When protons (H+ ions) flow through ATP synthase down from the inter- membranous space of the mitochondria into its matrix, synthesis of ATP from ADP and inorganic phosphate (P:) takes place. This phosphorylation event is known as oxidative phosphorylation. A. TRUE B. FALSE 10. At the end of glycolysis, each molecule of glucose has been oxidized to: A. two molecules of fructose B. two molecules of pyruvate C. two molecules of carbon-dioxide D. one molecule of sucrose 11. Which explanation/s may be valid for why cells do not use heat as a catalyst to carry out chemical reactions at a faster rate: A. heat will denature proteins B. heat will denature ATP C. heat is a highly specific catalyst D. both A and C E. both B and C

Explanation / Answer

6-D) Releases and requires.

Because breaking of bond is exergonic reaction and bond formation in endergonic reaction.

7-D Reducing the activation energy of the reaction.

By increasing the activation energy enzyme substrate complex will be made faster hence increasing the rate of reaction.

8-D increase the entropy of the cell and also of the universe.

9-TRUE.

10-B two molecules of Pyruvate.

11- D both A and C
