During a 3-minute boxing round, identify which energy system is the predominant system being used to fuel the specific activity described below:

ATP/PC - First punch thrown within 3 seconds of starting the round

Anaerobic - A continuous flurry of jabs and fast moves lasting about 45 seconds after 1.5 minutes into the round

Aerobic - Right at the end of 3 minutes while moving around the ring

Aerobic - During the 1-minute rest between rounds

Phosphagen can provide energy for about the first 3 to 10 seconds of high intensity and quick actions. After this time, (depending on the amount of oxygen available) anaerobic or aerobic respiration would take over. In this continuous boxing session, the more probable source of ATP would be anaerobic assuming that the demand for energy exceeds the normal time for aerobic respiration to take over. Anaerobic would last for about 10 to 90 seconds of performance duration. At rest, it would be aerobic respiration taking over.

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
