Question
to the inside the cell and The primary active transport process involves transporting to the outside the cell against their concentration gradients. a. sodium and potassium b. potassium and sodium c. sodium and glucose d. potassium and glucose 10. The following items are involved in the manufacture of proteins in a human cell. Place them in the correct sequence: A-DNA; B-RNA; C-ribosomes; D-nuclear pores; E-mRNA a. A,E,D,C,B b. A,E,C,B,D c. A, E, C, D, B d. E, A, B, C, D i I. If the nucleotide or base sequence of the DNA strand used as a template for mRNA would be synthesis is GATCA, then the sequence of bases in the corresponding mRNA a CUAUG b. CTAGT c. GUAUC d. CUAGU 12. which pathway in carbohydrate metabolism does not produce ATP? a. Glycolysis b. Electron transport chain c. Krebs Cycle d. The Transition Step in converting pyruvic acid into acetyl Co-A 13. In cellular respirationis the substance that is the electron donor while is the electron acceptor in the overall redox reaction equation. a. glucose; oxygen b. oxygen; carbon dioxide c. glucose; water d. oxygen; glucose 14. The net gain of ATP from the glycolysis pathway ismolecules. a. b. 4 . 36 d. 48 15. Which of the following statements is true about the electron transport chain? a. The electron transport chain is the only aerobic pathway of metabolism. b. The electron transport chain utilizes substrate-level phosphorylation. c. The number of ATPs produced by the electron transport chain is 2. d. All of these statements are true.Explanation / Answer
9. The answer is b. Potassium and sodium.
During primary active transport, the potassium ion enters in to the cell where as the sodium ion moves outside the cell againist their concentration gradient.
10. The answer is a. A, E, D, C, B
The DNA template (A) synthesizes the mRNA (E), it exits from the nuclues through nucleopores (D) later in cytoplasm the ribosomes (C) binds to mRNA and synthesiszed the polypeptide with the help of tRNA (B)
11. The answer is a. CUAGU
In the synthesis of mRNA, A codes to U, G codes to C, C codes to G and T codes to A. So, the transcript is CUAGU.
12. The answer is d. The transition step in converting pyruvic acid into acetyle co.A.
In this step only NADH is produced.
In Glycolysis and TCA cycle the ATP is produced by substrate level phosporelation where as in ETC the ATP is produced by oxidative phosphorelation.
