  • Q6
    What is the significance of beta oxidation in maintaining blood glucose levels during fasting?
    Beta oxidation triggers insulin release to increase blood glucose levels.
    Beta oxidation converts glucose into glycogen for long-term storage.
    Beta oxidation provides an alternative source of energy by breaking down stored fatty acids, thus sparing glucose for essential tissues like the brain.
    Beta oxidation promotes gluconeogenesis to generate glucose from amino acids.

  • Q7
    What is the initial step in beta oxidation of fatty acids?
    Fatty acids are broken down into glycerol and free fatty acids.
    Fatty acids are oxidized by acyl-CoA dehydrogenase.
    Fatty acids are activated by linking with coenzyme A (CoA) to form acyl-CoA.
    Fatty acids are esterified into triglycerides.
