Question
1.) Explain reasons why 6 molecules of H2O and 6 molecules of O2 are required in order to breakdown 1 molecule of glucose during aerobic respiration in mammalian cells?
2.) Spinach can tolerate against cold weather and increase its sweetness when it grows under a light frost. Explain the reason at the cellular level why spinach becomes sweeter after it survives under the freezing temperature. Your explanation should address the mechanism that increases the sweetness of spinach. (Hint: over 70% of cellular composition is water. In order for cells to survive in freezing conditions, cells need to do something to maintain water in liquid state)
Explanation / Answer
2. In order to maintain water in liquid state during winter, spinach import glucose into the cell, which increases the tonicity of the cytoplasm. Increasing tonicity increases the freezing temperature. Thus, they become sweet in taste when grown under light frost.
