Problems 20
- Which of the following best describes the Krebs cycle?
- What is not present during the Krebs cycle?
- Where does the citric acid cycle occur?
- 1 pyruvate produces 2 CO2_22, 3 NADH, 1 FADH, and 1 ATP. How many of these would be produced from one glucose molecule?
- Where in the cell does the Krebs cycle take place?
- For every cycle of glycolysis, the citric acid cycle runs woah‾\underline{\phantom{woah}}woah time(s).
- The citric acid cycle is an woah‾\underline{\phantom{woah}}woah process, meaning it woah‾\underline{\phantom{woah}}woah oxygen.
- The cytoplasm is to glycolysis, as the woah‾\underline{\phantom{woah}}woah is to the citric acid cycle.
- Which letter corresponds to the area of the mitochondria that the Krebs cycle occurs?
- Using the picture above, which number depicts the correct order of processes in aerobic respiration?
- Which of the following electron carriers are involved in the Krebs cycle? Check all that apply.
- Which of the following are products of the Krebs cycle? Check all that apply.
- Which of the following is not directly used by the Krebs cycle?
- Fill in the blank. The cytoplasm is to the cell, as the woah‾\underline{\phantom{woah}}woah is to the mitochondrion.
- The picture above shows the beginning of the Krebs cycle. What is the two carbon molecule?
- The diagram above shows one reaction of the Krebs cycle. What is the 6-carbon molecule?
- After the completion of the Krebs cycle, what is the correct count of total ATP, NADH, and FADH2_22 produced in cellular respiration? (Remember, glycolysis produces a net yield…
- Which of the following objects serves a similar function to NAD+^++ and FADH?
- Which of the following is false about the Krebs cycle?
- Which of the following molecules contains electrons for cellular respiration? Select all that apply.
