Cellular respiration uses one molecule of glucose to produce

Cellular respiration uses one molecule of glucose to produce_____. What docs cellular respiration breakdown? What are the products of glycolysis? What arc the electron carriers in cellular respiration? Describe the two main types of fermentation. What is the starting molecule for the Krebs cycle? Explain how high-energy electrons are used by the electron transport chain. Identify the three pathways the body uses to release energy during exercise. Compare and contrast photosynthesis to respiration.

Solution

Answer:

62. Cellular respiration uses one molecule of glucose to produce 36 ATP molecule (Aerobic respiration).

63. During cellular respiration, glucose is broken down to carbon dioxide and water.

64. 2 molecules of pyruvate, 2 molecules of ATP and 2 molecules of NADH along with hydrogen ions and water.

65. Electron carriers in cellular respiration are: NAD⁺ (in glycolysis) and FAD (in Kreb\'s cycle).

66. The two main types of fermentation are:

Alcohol fermentation: In this process, sugars such as glucose, sucrose and fructose are converted to ethanol and carbon dioxide.

C₆H₁₂O₆ 2 C₂H₅OH + 2 CO₂

Lactic acid fermentation: In this process, sugars are converted to lactic acid but there is no production of carbon dioxide.

C₆H₁₂O₆ 2 CH₃CHOHCOOH

67. The starting molecule of Kreb\'s cycle is acetyl-CoA. At the end of glycolysis, pyruvate molecules are converted to acetyl-CoA befor it can enter Kreb\'s cycle.

68. High energy electrons are used (along with hydrogen ions) to convert ADP to ATP. The electrons are passed to the carriers down the membrane. This process is coupled to pumping of protons into the intermembrane space. Some of the electrons in this step goes to the water molecules. The pumping of protons into the intermembrane space creates a proton motive force which results in the production of ATP by ATP synthase.

69. (a) Phosphagen (Creatinine phosphate pathway)

(b) The aerobic respiration (pathway)

(c) The anaerobic respiration (pathway)
