Physiology of Exercise - bioenergetics - Phosphocreatine splitting kinetics

3 important questions on Physiology of Exercise - bioenergetics - Phosphocreatine splitting kinetics

What happens with [ADP] when [PCr] decreases?

Then [ADP] increases. (Less transition from ADP to ATP? so more ADP?)

What might be the signal that triggers the mitochondria for O2 uptake (as reaction to O2 debt)?

The increase of [ADP] or decrease of [PCr]

What reaction takes place during early recovery with respect to the O2 debt?

[PCr] increases and [ADP] decreases. The change in [PCr] is indistinguishable from the change in VO2, so an increase in [PCr] would mean an increase in VO2 (O2 debt)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
