Cellular Respiration and Fermentation FIGURE 2 Stages of cellular respiration and fermentation. Celibalar respiration consists of ghycolysis, the citric acid cycle, and the electron transport chain. Ghycolysis is also a sage in fermenstation Glucese Cysosol Pyruvate Mtochondrion Ethanoi Co Before you begin today's lab topic, refer to the preceding paragraph and Figure 2 fermentation and cellular respiration by answering the following questions. as you review major pathways, reactants, and products of 1. Which processes are anaerobic? 2. Which processes are aerobic? 3. Which processes take place in the cytoplasm of the cell? 4. Which processes take place in mitochondria? 5. What is the initial reactant in cellular respiration? 6. What is (are) the product(s) of the anaerobic processes? 7. What is (are) the product(s) of the aerobic processes? 8. Which gives the greater yield of ATR alcoholilc fermentation or cellular respiration?

Answer 1

Hi Answer:

Q.1. Which processes are anaerobic?

Answer: Fermentation process is anaerobic in nature. In this process bacteria, yeast and other microorganism carry out their metabolism. Sugar is being metabolized by fermentation in the absence of oxygen.

Q.2. Which processes are aerobic?

Answer: Cellular respiration is aerobic in nature. It is a complex set of metabolic reactions which took place in the cells of the organism where ATP is produced from the biochemical energy and the waste product is released.

Q.3. Which processes take place in the cytoplasm of the cells?

Answer: Fermentation took place in the cytoplasm of the cell.

Q.4. Which processes take place in the mitochondria?

Answer: Cellular respiration took place in the mitochondria of the cell. It is divided into three main phases i.e. glycolysis, Krebs cycle, and electron transport chain.

Q.5. What is the initial reactant in cellular respiration

Answer: Oxygen and glucose are the reactants of cellular respiration.

Q.6. What is the product of the anaerobic process

Answer: The major product of the anaerobic process (Fermentation) are: The most common product are ethanol, lactic acid, carbon dioxide, and hydrogen gas.

Q.7. What is the product of the aerobic process

Answer: The main product of the aerobic process (cellular respiration) is ATP whereas the Carbon dioxide and water are the waste product of this process.

Q.8. Which gives the greater yield of ATP, alcoholic fermentation or cellular respiration?

Answer: The cellular respiration (aerobic process) gives more ATP yield than the alcoholic fermentation. Cellular respiration produces 32 ATP molecules/glucose molecule whereas alcoholic fermentation yields and 2 ATP molecules/glucose molecule.
