Directions: This is a modified TRUE or FALSE activity. Write the word TRUE if the underlined word/phrase being referred to is correct. If it is FALSE, change the word/phrase to make the whole statement correct based on the concept of cellular respiration. Write your answer on a separate sheet of paper.
_____1. Fermentation and anaerobic respiration enable the cells to produce ATP without the use of oxygen.
_____2. The term cellular respiration includes both aerobic and anaerobic processes. _____3. Fermentation is a complete degradation of sugars or other fuel that occurs without the use of oxygen. _____4. An electron transport system consists of a number of molecules, majority are proteins, located in the matrix of the mitochondria of eukaryotic cells and the plasma membrane of aerobic prokaryotes.
_____5. Pyruvate oxidation and the citric acid cycle, oxidative phosphorylation: electron transport chain and chemiosmosis are the metabolic stages reserved for cellular respiration.
_____6. The breakdown of glucose to carbon dioxide is completed in the electron transport chain.
_____7. ATP synthase is the enzyme that makes the bulk of the ATP from ADP and Pi by chemiosmosis.
_____8. ATP synthase uses the energy of an existing hydrogen ion gradient to power ATP synthesis.
_____9. Phosphorylation of ADP to form ATP stores at least 14.6 kcal per molecule of ATP.
_____10. Citric acid cycle generates 2 ATP whether oxygen is present or not, whether the conditions are aerobic or anaerobic.
