question 1 (5 points) listen in order to digest food, the human body requires a) high activity to burn off energy. b) sleep to perform the necessary break down of molecules in food. c) enzyme catalysts to speed up reactions. d) physical reactions in the stomach lining. question 2 (5 points) listen an atom of chlorine has several valence electrons in its a) third shell. b) first shell.

Answer

Brief Explanations:

  • For Question 1: Enzymes are biological catalysts that speed - up the chemical reactions involved in food digestion. High activity for burning energy is related to metabolism but not directly to digestion. Sleep is not directly involved in breaking down food molecules. Physical reactions in the stomach lining are not the main requirement for food digestion.
  • For Question 2: Chlorine has an atomic number of 17. Its electron - configuration is 2, 8, 7. The valence electrons are in the outermost shell, which is the third shell for chlorine. The first shell has 2 electrons and is not the shell with valence electrons for chlorine.

Answer:

Question 1: C. enzyme catalysts to speed up reactions. Question 2: A. third shell.
