Exercise 5: Respiration

• What is the process wherein organic compounds are broken down enzymatically to release chemical energy?

  Cellular respiration
• What does ATP stand for?

  Adenosine Triphosphate
• What is the photosynthetic product for autotrophs used for cellular respiration?

  Glucose
• What type of respiration requires oxygen?

  aerobic
• what type of respiration does not require oxygen?

  Anaerobic
• What are the factors that influence the rate of respiration?

  Temperature;

  Substrate
• What is the strong reducing agent used in the consumption of O2 in aerobic respiration that hindered the seedling growth?

  alkaline pyrogallol
• What is a by-product of respiration?

  Carbon dioxide
• In the production of CO2 in Fermentation, among yeast-glucose and 10% glucose, which will have a higher precipitate of BaCO3?

  Yeast-glucose
• What microorganism undergoes fermentation to extract energy from glucose that is used in the experiment?

  Yeast
• Fermentation - type of anaerobic respiration which does not require oxygen to break down glucose but yields much less ATP
• Glucose - monosaccharide and is easily utilized into enzymatic pathways
• What is sucrose a disaccharide of?

  Glucose and fructose
• Among the substrates of 10% glucose, yeast suspension, yeast-glucose suspension, and yeast-sucrose suspension, what will have the highest rate of fermentation?

  Yeast-glucose suspension
• In the last part of the experiment, among all the temperature conditions such as refrigerator, room temperature, warm water bath, and hot water bath, what is the optimum for fermentation of yeast?

  Room temperature
