Concept explainers
Interpretation:
To identify the mobile electron carrier in the electron transport chain.
Concept introduction:
Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. The reaction of the formation of the water is:
Mobile electron carriers are species that transfers electrons between the various complexes of the electron transport chain but is not directly associated with any of the four complexes. Examples of mobile electron carriers include

This genetic disease results from deficiency of the enzyme glucose-6-phosphatase. The metabolic outcomes of GSD I are likely to include: O Low blood glucose, increased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, decreased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, increased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, decreased blood pH, decreased glycogen storage in liver and kidneys High blood glucose, decreased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, increased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, increased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, decreased blood pH, increased glycogen storage in liver and kidneysarrow_forwardt Plase answer both of youarrow_forward
