Description

1. What process occurs in Box A? a. Glycosis 2. What process occurs within Box B? a. The citric acid cycle 3. What molecule is indicated by the letter D? a. Oxygen 4. What’s the correct sequence of steps as energy is extracted from glucose during cellular respiration. a. glycolysis → acetyl CoA → citric acid cycle → electron transport chain 5. What is the correct general equation for cellular respiration? a. C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy 6. Which of the following processes takes place in the cytosol of a eukaryotic cell? a. Glycosis 7. In what organelle would you find acetyl CoA formation, the citric acid cycle, and the electron transport chain? a. Mitochondrion 8. Which statement describes glycolysis? a. This process splits glucose in half and produces 2 ATPs for each glucose. 9. Which statement describes the citric acid cycle? a. This process produces some ATP and carbon dioxide in the mitochondrion. 10. Which statement describes the electron transport chain? a. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. 11. Which of the following equations represents photosynthesis? a. 6CO2 + 6H2O → C6H12O6 + 6O2 12. In which of the following organelles does photosynthesis take place? a. Chloroplast 13.
