Exam #3Topics Include:  Cellular Respiration, Enzymes, Energy Due Date/Time: 12:00 PM (NOON) FRIDAY OCTOBER 31, 2025.  Point Value = 100 points Maximum Time Limit = 75 Minutes (in one sitting) Must be taken in one 75-minute sitting/session. Honorlock is required to take this exam. Remember to comply with the identification requirements, and show your photo ID, please. Acceptable forms of ID include: CCAC Student ID, Driver’s License, or other Government-Issued ID.  Spelling counts. IF YOU NEED TO USE SCRAP PAPER, YOU MUST SHOW THE BLANK PAPER TO THE CAMERA FIRST, THEN WRITE WHAT YOU NEED TO, THEN SHOW THE WRITTEN-ON PAPER TO THE CAMERA. Be sure that you type all your answers and any work into the exam, too, please. IF YOU NEED TO USE A CALCULATOR, IT MUST BE A REGULAR CALCULATOR (HAND-HELD OR ON SCREEN). PHONES AREN’T PERMITTED. YOU MUST SHOW THE CALCULATOR TO THE CAMERA IF IT IS HAND-HELD.  Reminder:  If students do not submit exams by the scheduled due date and time, a grade penalty will be applied. If the exam is submitted within 24 hours of the original due date/time (that means 1 minute late up to 24 hours late), then a 25% grade deduction to the exam grade will be applied. If the exam is submitted 24 hours to 48 hours after the original due date/time, then a 30% grade deduction to the exam grade will be applied. Exams will NOT be accepted after 48 hours after the scheduled due date and time, and a zero (0) will be the grade recorded for that exam.  This information is in the Course Outline. REMINDERS: Exams, tests, and quizzes are closed books, closed notes, closed slides, closed assignments, and taken individually. No additional devices allowed other than the one (1) being used for the exam/test/quiz.

If the difference in energy between reactants (glucose and oxygen) and products (CO2 and water) is 686 kcal of energy, what happened to rest of the energy?  Explain in one (1) sentence.

How many kilocalories (kcal) of energy (ATP) are produced (net) in Cellular Respiration?    SHOW YOUR WORK.

How many kcal of energy is the difference between the amount of kcal produced (net from ATP) in Cellular Respiration (which you calculated in a separate question) and the energy difference between reactants and products of the reaction (amount given to you in a separate question)? SHOW YOUR WORK.

Which is true for the cellular respiration reaction?

Explain (in 2-4 sentences) how temperature affects enzymes. Include the following in your answer: too high, too low, changes in rate of reactions, denature, and any other information necessary to describe this.

The metabolic function of fermentation is to

Complete the following table with the number of ATP molecules that enter each reaction. Please include the letters with your answers. For example: If letter Z is zebra, then type Z = Zebra.  table ATP NEEDED(1).png

Complete the following table with the correct phase, substrate, and/or end product. Please include the letters with your answers. For example: If letter Q is lysosome, then type Q = Lysosome.  (If you see 2 tables, they are the same, but using 2 different formats.)   Picture4.png Phases Table.png
