NGSS.HS-LS2-3

During exercise, the heart rate increases to:

• Supply more lactic acid to the muscles for anaerobic respiration
• Supply more oxygen and glucose to the respiring cells
• Keep up with the pulse rate

NGSS.HS-LS2-3

Why does anaerobic respiration occur during hard exercise?

• There may be insufficient oxygen supplied to the muscle cells
• Carbon dioxide builds up in the respiring muscle cells
• Anaerobic respiration releases more energy from glucose than aerobic respiration
