Respiration and Fermentation Name 1 Cellular respiration and

Respiration and Fermentation Name: 1. Cellular respiration and fermentation transfer the energy from glucose bonds into another important energy molecule called which is used by the cells to do work. 2. Does fermentation occur inside the mitochondria outside them? or of 3. What produces more energy, fermentation, or cellular respiration? 4. In the fermentation experiment last week, how could you tell if yeast was fermenting the glucose? a) It tested positive for the presence of starch b) CO2 gas was produced c) The DPIP became more transparent d) The glucose gained electrons 5. Does DPIP loses its blue color when a) It gets oxidized. b) It is broken down by the mitochondria. c) It accepts the electrons and gets reduced d) When it is broken down by yeast. 6. What instrument was used to measure light transmittance? a) a spectrometer b) a spectrophotometer c) a transpirometer d) a respirometer 7. You are measuring respiration in two cuvettes. In the cuvette A, the Transmittance is 17%; in cuvette B the Transmittance is 25%. If both started at 15%, in which cuvette did the most respiration occur?

Solution

1. ATP

2. Outside the mitochondria

3. celllar respiration produces more energy (about 38 ATP\'s)

4.b. DPIP becomes transparent

DPIP when reduced changes from its original blue color to colorless as it accepts the electrons

5.C.

DPIP when reduced changes from its original blue color to colorless as it accepts the electrons

6.b. spectrophotometer
